Voss+Agin Diamonds Review: Lab-Grown Diamond Stud Earrings in 14k Gold, What You Get for the Price and What Lab-Grown Really Means

Our verdict

Yes, if you want real diamond studs to wear and enjoy, not to resell. Voss+Agin sells lab-grown, AGI-certified G/VS diamond studs in solid 14k gold from $299.99 for 1 carat total weight, half the price of a similar pair in its own store. Returns are free for unworn pieces within 30 days. Lab-grown diamonds keep falling in price and have little resale value, and the crossed-out "retail" prices are inflated. Voss+Agin Diamonds scores 5.9 out of 10, held back by marketing claims and no independent ratings.

The short version

• What it is: lab-grown diamond stud earrings in solid 14k white or yellow gold, with AGI certificates.
• Price: $299.99 for 1 carat total weight, $599.99 for 2 and $899.99 for 3 on 4 October 2026.
• Best trait: a low price for G/VS diamonds in solid gold.
• Biggest drawback: lab-grown diamonds hold little resale value.
• Our score: 5.9 out of 10.

Pros & cons

The pros come from the specification and price. The cons are about resale value, inflated reference prices, the less familiar certificate and missing independent reviews.

How it works

Voss+Agin grows diamonds using HPHT (high pressure, high temperature), a process that recreates the heat and pressure that form diamonds underground, according to the page. The stones are graded G colour and VS clarity with a round brilliant cut, certified by AGI, and set in four-prong 14k gold settings with push backs. Each pair comes in a gift box.

You choose the total carat weight for the pair: 1 carat (two half-carat stones), 2 carats or 3 carats, in white or yellow gold. The page says the earrings are handcrafted by jewellers in the USA. A different kind of personal gift is covered in our Artkive review, which turns children's art into books.

1. 01

   Choose the size and metal

   Step 1: Pick 1, 2 or 3 carats total weight for the pair, and white or yellow 14k gold.

2. 02

   Receive the studs and certificate

   Step 2: The earrings arrive in a gift box with an AGI certificate for the stones, which records colour, clarity and cut.

3. 03

   Wear or return unworn

   Step 3: Wear them daily, or return them unworn within 30 days of delivery for a full refund after requesting a return number.

Why lab-grown has taken off

Lab-grown diamonds moved from novelty to mainstream over the past decade, as production scaled up and prices fell. Many jewellers now sell both. For earrings, where buyers rarely inspect stones under magnification, lab-grown offers bigger stones for the money.

What the photos show

The page shows the studs in a black gift box, close-ups of a single stud on a fingertip, a jeweller setting a stone, an ear with three sizes, and many lifestyle photos of people wearing small studs. The product photos match the description.

The name

Voss+Agin presents itself as a fine jewellery brand focused on lab-grown stones. The offer page sells only its classic round studs, while the brand store has a much wider range.

Lab-grown is not fake

Lab-grown diamonds are sometimes confused with imitations like cubic zirconia or moissanite. They are not imitations; they are diamond. The FTC's guides require clear disclosure of origin, not a label suggesting they are fake.

Lab-grown vs mined

Lab-grown diamonds have the same chemical makeup, crystal structure, hardness (10 on the Mohs scale) and light behaviour as mined diamonds, as the page's comparison table says. The difference is origin and price.

HPHT and CVD

There are two main ways to grow diamonds. HPHT presses carbon at very high temperature and pressure. CVD (chemical vapour deposition) builds diamond layer by layer from a carbon gas. Both produce real diamond; quality depends on the grower and any treatments after growth.

Cut

Round brilliant is the classic stud shape, designed to maximise sparkle. The page says the stones are precisely cut but does not give a cut grade. Cut quality affects brightness more than colour or clarity at earring sizes.

What G and VS mean

G colour is near-colourless, the top of the "near-colourless" range. VS (very slightly included) clarity means small inclusions that are hard to see without magnification. Together they are a solid, popular specification for earrings, which are seen from a distance.

Colour in earrings

Earrings are seen from a distance, so slight colour differences are hard to notice. G colour looks white to most people. Spending more on D or E colour makes little visible difference in studs.

Clarity in earrings

At VS clarity, inclusions are not visible to the naked eye in normal wear. Paying more for VVS or flawless makes no visible difference in studs.

The four Cs

Diamonds are graded on colour, clarity, cut and carat weight. For studs, cut and size affect appearance most. G/VS is a sensible balance, leaving more budget for size.

Carat total weight

"CTW" means carat total weight for both earrings. A 1 CTW pair has two stones of about half a carat each. The page's ear graphic shows the size difference between 1, 2 and 3 carats.

White or yellow gold

White gold suits a classic, icy look and is often rhodium plated, which can wear and need re-plating every few years. Yellow gold gives a warmer look and does not need plating. The page lets you choose either.

Handcrafted in the USA

The page says each pair is handcrafted in the US by artisan jewellers. Setting studs is skilled work, but it is also commonly done at scale. We could not verify where these are set.

Gold weight

The page does not give the weight of gold in each setting. Stud settings use only a small amount of gold, so the stones are the main part of the value.

Matching stones

A good pair of studs uses two stones closely matched in size, colour and cut, so they look identical on each ear. The page says stones are selected carefully. Check they match when they arrive.

Four-prong settings

Four prongs hold the stone securely while letting in plenty of light, which helps sparkle. They also show more of the diamond than six prongs. Prongs can catch on fabric or hair occasionally.

Solid 14k gold

The page says the settings are solid 14k gold, not plated. That matters, as some pieces in the brand's own store are gold over sterling silver. 14k gold is about 58% gold, harder and more durable than 18k for daily wear.

The gift box

Each pair comes in a black box with the Voss+Agin logo, as the photos show. A presentation box matters for gifts and for keeping studs safe between wears.

Push backs vs screw backs

Push backs are standard on studs and easy to use. Screw backs are more secure but slower to put on. For larger, more valuable studs, some people upgrade to locking backs.

Comfort

Half-carat studs are light and comfortable for all-day wear. Larger studs weigh more and sit further from the ear, so 3 carat total weight pairs may droop on thin lobes without supportive backs.

What it does not do

Lab-grown diamonds do not hold resale value like mined diamonds once did, and the earrings are not an investment.

Who it's for

Voss+Agin suits buyers who want real diamond studs at a fraction of mined prices, gift buyers looking for classic jewellery with no sizing, and people who prefer lab-grown for environmental or ethical reasons. It does not suit anyone buying for investment, buyers who want mined diamonds or GIA certificates, or people who need screw-back studs.

• Buyers who want real diamond studs at a fraction of mined-diamond prices
• Gift buyers looking for classic, one-size jewellery
• People who value lab-grown over mined for environmental or ethical reasons

Why Voss+Agin appeals

Diamond studs are a classic many people want but find expensive. Lab-grown diamonds make sizes like 1 or 2 carats affordable, and the page's prices are low even for lab-grown. The gift box and certificate make it feel like fine jewellery.

People who lose earrings

If you are prone to losing earrings, a lower-priced lab-grown pair hurts less to replace than mined diamonds. That is a quiet advantage of lab-grown.

Sustainability-minded buyers

People who avoid mined products for environmental reasons often choose lab-grown. If that matters to you, ask the seller about the energy source used to grow the stones.

People with metal sensitivities

Solid 14k gold is generally better tolerated than plated jewellery, where the base metal can show through and irritate skin. That is a practical reason to choose solid gold studs over cheaper plated pairs.

Gift buyers

Studs need no ring size or wrist measurement, which makes them a safe gift, as the page says. Customer quotes describe buying them for daughters, wives and graduations.

Second piercings

A customer mentions buying a pair for a second piercing to wear constantly. Smaller sizes suit upper-lobe and second piercings better; 3 carat total weight studs are large.

Men

The page shows a man wearing a single stud. Men who wear studs often choose smaller sizes. Single earrings are not offered on the page, so you would buy a pair.

Matching sets

The brand's store sells matching pendants, tennis bracelets and rings. Buyers building a set can match metal colour and stone grade, though the offer page sells only studs.

Professionals

Small diamond studs are a common, understated choice for work. A 1 carat total weight pair in white gold suits most office settings, as the page's photos suggest.

First diamonds

For someone buying their first diamond jewellery, a 1 carat total weight pair at $299.99 is an accessible start, in solid gold that should last.

Everyday wearers

Solid gold and durable diamonds suit daily wear, including at work and in the gym, though removing them for sport is wise. Customer quotes describe wearing them constantly.

Budget-conscious buyers

At $299.99 for a 1 carat total weight pair in solid gold, the offer is cheaper than many high-street jewellers' lab-grown studs. For people who want diamonds on a budget, it is worth comparing.

Mothers and daughters

Customer quotes describe parents buying studs for daughters' birthdays and graduations. A classic pair is a lasting gift that suits any age.

Ethical shoppers

Lab-grown diamonds avoid mining. They still use significant energy to produce, so their environmental footprint depends on how the factory is powered.

Bridal and special occasions

The page shows a bride wearing studs. Diamond studs are a popular wedding-day and bridesmaid gift. Order early enough to inspect them and return within 30 days if needed.

Anniversary and milestone gifts

Diamond studs are a traditional anniversary gift. Some recipients care whether the stones are mined or lab-grown, so it is worth knowing their view before buying.

Buyers who value disclosure

Some people want to tell friends their diamonds are lab-grown, as a positive choice. Others prefer to say nothing. Either way, the stones look identical to mined diamonds to the eye.

People upgrading old studs

If you already own small studs, a larger lab-grown pair is an affordable upgrade. Keep the old pair as a spare, since lab-grown trade-in values are low.

Who should skip it

Skip Voss+Agin if you want diamonds that hold value or might be resold. Skip it if you prefer mined diamonds or want GIA grading specifically. And skip it if push backs worry you; the page shows push backs, and the brand store offers some screw-back pieces separately.

• Anyone buying diamonds as an investment or for resale value
• Buyers who insist on mined diamonds or GIA certificates
• People sensitive to the push-back style who prefer screw backs

How much do Voss+Agin earrings cost, and is it a good deal?

On 4 October 2026, the offer page listed 1 carat total weight for $299.99, 2 carats for $599.99 and 3 carats for $899.99, with free shipping. The brand's own store listed a 1 carat G/VS pair in 14k gold at $599 on 5 October 2026, so the offer is genuinely cheaper there. The crossed-out "retail" prices of $849, $1,699 and $3,599 do not reflect normal selling prices.

Voss+Agin offer prices

Is the offer price real?

The offer price is roughly half the brand store's own listing for comparable pairs, so it does look like a genuine discount against Voss+Agin's usual prices. Whether it beats other lab-grown sellers depends on the day.

Why prices differ

Offer pages often run promotions that differ from a brand's own store. It is worth checking both on the day you buy, since either may change.

Price per carat

All three sizes on the offer page work out at about $300 per carat total weight. Prices usually rise faster than carat weight for larger stones, so the flat rate makes the larger pairs relatively good value.

Brand store comparison

On 5 October 2026, the Voss+Agin store listed 1.00 CTW G/VS studs in 14k gold at $599, 2.00 CTW E/VS at $1,249 and 3.00 CTW G/VS in solid 14k gold at $1,999. The offer page's prices were roughly half. The store also sells lower-priced pairs in gold over sterling silver.

The "retail" prices

A 75% saving against a $849 "retail" price sounds dramatic. The brand's own store price for a similar pair was $599, and lab-grown diamond prices across the market have fallen sharply. Judge the deal against current prices, not the crossed-out figure.

What 1 CTW looks like

Each half-carat round stone is about 5 mm across. Two-carat total weight pairs have stones of about 6.5 mm each, and three-carat pairs about 7.4 mm, roughly. The page's ear graphic gives a sense of scale.

Free shipping and taxes

Shipping is free in the US. Sales tax depends on your state. International buyers may face import duties on jewellery, which can be significant.

Lab-grown prices in context

Industry reporting, such as this overview of falling lab-grown prices, describes retail prices dropping steeply since 2020. That makes $300 per carat total weight in solid gold competitive, but it also means today's price may be higher than tomorrow's.

Which size to buy

One carat total weight is a classic everyday size. Two carats look noticeably larger and suit evenings and statement looks. Three carats total weight is large for daily wear and may be heavy on thin lobes.

Free shipping

The page shows free shipping on all three sizes. That keeps the price straightforward.

The return policy

Returns are complimentary within 30 days of delivery for a full refund. Earrings must be unworn and undamaged, with the box, pouch, documents and certificate. You need a return authorisation number before sending. Refunds go to the original payment method after inspection.

What to do: inspect the earrings and certificate as soon as they arrive, and do not wear them out until you are sure.

"Unworn" in practice

Trying the earrings on briefly to check how they look is usually accepted, but wearing them out for an evening may not be. Keep them clean and in the box until you decide.

Delivery

The FAQ says orders ship within 24 to 48 hours and arrive in three to five business days in the US on average. For gifts, allow time to inspect them before the occasion.

Lost earrings

The policy does not cover loss. Some jewellers sell single replacement studs; ask Voss+Agin whether they can match one if you lose an earring.

Approval and inspection

All returns are inspected and approved at the company's discretion. Send them back exactly as instructed, using the return method provided, to keep the refund straightforward.

Repairs

The policy describes repair or service for workmanship concerns after inspection, at the company's discretion. Loss, accidents and normal wear are not covered, and fees may apply.

Are Voss+Agin's claims about lab-grown diamonds accurate?

The core claims are correct: lab-grown diamonds are real diamonds with the same properties. But "even an advanced diamond tester can't tell the difference", "outdated mined diamonds" and "conflict diamonds use slave labor" are oversimplified. Gem labs can identify lab-grown stones, and most mined diamonds are not conflict diamonds. Under the FTC Jewelry Guides, lab-grown stones must be clearly described as such, which the page does.

"All diamonds are the same under a microscope"

Physically and chemically, yes. Gem labs use advanced spectroscopy and growth-pattern analysis to tell them apart, which is why grading reports state whether a stone is lab-grown.

Treatments after growth

Some lab-grown diamonds are treated after growing to improve colour. That is common and legal, but reputable grading reports note it. Check whether the AGI report mentions any treatment.

Laser inscriptions

Many graded lab-grown diamonds carry a tiny laser inscription on the girdle with the report number and the words "lab grown". The page does not say whether these stones are inscribed. A jeweller with a loupe can check.

"Passes a diamond tester"

Simple thermal testers sold to jewellers detect diamond versus imitations like cubic zirconia. They cannot distinguish lab-grown from mined. That is true, but "advanced" lab equipment can.

The FTC Jewelry Guides

The FTC's Jewelry Guides say a lab-created diamond must be described with words like "laboratory-grown", "laboratory-created" or "[manufacturer]-created". The page calls the stones lab-grown throughout, which meets that standard.

"Mined diamonds are outdated"

The page calls mined diamonds outdated. Mined diamonds are still the majority of high-end sales, and some buyers value their natural origin and rarity. Lab-grown is a different choice, not a replacement for everyone.

"Conflict diamonds use slave labor"

Conflict diamonds and abusive mining exist, but the international Kimberley Process aims to keep conflict stones out of trade, and much mining is regulated. Lab-grown avoids those questions entirely, which is a fair point, but the page paints all mining with one brush.

Kimberley Process

The Kimberley Process is an international certification scheme set up to stop conflict diamonds entering the market. Critics say it has gaps, but it means most mined diamonds sold today are not conflict diamonds.

"Made in the USA"

The page says the diamonds are created and the earrings handcrafted in the USA. Much of the world's lab-grown diamond production is in Asia. We could not verify where these stones are grown.

"Last multiple lifetimes"

Diamonds are extremely hard and durable, so the stones themselves will last. Gold settings can wear and prongs can loosen over decades, so periodic checks matter.

"Ethically grown"

Lab-grown avoids mining's human and environmental issues, but manufacturing uses a lot of electricity. How green it is depends on the energy source, which the page does not describe.

"AGI certified"

AGI is a gem grading laboratory. GIA and IGI grade most lab-grown diamonds in the US market and are better known. An AGI report still records the grades, but some buyers prefer a GIA or IGI report for consistency.

Why the certificate matters

A grading report confirms the stone's grades and that it is lab-grown. It also helps with insurance and any future repairs or resetting. Keep it with your receipt.

"95% positive" and "20,000+ people love Voss+Agin"

The page gives no source. We found no Trustpilot page for the brand.

Is Voss+Agin better than mined diamonds, moissanite or other lab-grown sellers?

For value, lab-grown beats mined; for even lower cost, moissanite beats both; against other lab-grown sellers, this offer is competitive. Mined diamond studs of the same size cost many times more. Moissanite looks similar but is a different gem. Large lab-grown retailers sell similar studs, often with IGI or GIA reports, at prices worth comparing.

What lab-grown means for value

Lab-grown supply is not limited the way mined supply is, which is why prices keep falling as production grows. Buy lab-grown studs for how they look and feel, and do not expect them to keep their price.

Who prefers mined

Some people value the geological history of a mined diamond, or plan to pass jewellery down as an heirloom with lasting value. For them, a smaller mined stone may mean more than a larger lab-grown one.

Voss+Agin vs mined diamonds

Mined diamonds of the same size and grade cost many times more, and resale value is partly about rarity. If you want a mined stone for sentimental or traditional reasons, lab-grown will not satisfy that.

Resale realities

Lab-grown diamonds have a thin resale market. Jewellers rarely buy them back, and second-hand prices are low. Mined diamonds also resell well below retail, but generally retain more value.

Mined diamond price context

Mined diamond studs of the same total weight and grade can cost several thousand dollars at mainstream jewellers. That gap is why lab-grown studs have become so popular for earrings.

Durability compared

Diamond, lab-grown or mined, is the hardest gem and resists scratches best. Moissanite is close behind. Softer stones and cubic zirconia scratch and dull faster.

Voss+Agin vs moissanite

Moissanite is nearly as hard as diamond and sparkles with more rainbow fire. It costs less but is not a diamond, which matters to some recipients.

Choosing between sellers

When comparing lab-grown studs, line up carat total weight, colour, clarity, metal (solid or plated), back type, certificate lab, warranty and return terms. Price per carat in solid gold is the most useful single number.

Where Voss+Agin wins

Solid gold, G/VS diamonds and a certificate at around $300 per carat total weight, with free shipping and returns. For buyers who want real diamond studs without spending heavily, that is a strong package.

Where it loses

Against mined diamonds, it loses on rarity and resale. Against GIA- or IGI-graded lab stones, it loses on certificate recognition.

Voss+Agin vs white sapphire

White sapphires are hard and durable but less brilliant than diamond. They are a lower-cost natural alternative. Voss+Agin's store also sells lab-created sapphire jewellery.

Voss+Agin vs cubic zirconia

Cubic zirconia studs cost very little and look sparkly at first, but scratch and cloud over time. Lab-grown diamonds stay bright for decades. For daily wear, the difference shows.

Value of a certificate

GIA reports are the most recognised; IGI reports dominate lab-grown sales. AGI reports are less common, so a jeweller may want to verify the grades if you ever reset or sell the stones.

Voss+Agin vs gold-over-silver studs

The brand's store sells cheaper studs in gold over sterling silver. Plating wears with time, especially on posts. For daily wear, solid gold, as offered here, lasts better.

Voss+Agin vs high-street jewellers

High-street jewellers increasingly sell lab-grown studs, with the advantage of seeing them in person and local after-sales service. Prices are often higher than online, but you can compare sparkle side by side.

Voss+Agin vs other lab-grown sellers

Many online jewellers sell lab-grown studs with IGI or GIA reports. Compare carat weight, colour, clarity, metal, back type, certificate and return terms. The offer price here is competitive for solid gold.

Is Voss+Agin legit, and what should you check before buying?

Voss+Agin is a real jewellery brand with its own store and a broad range of lab-grown pieces. Check the certificate matches the earrings, confirm the metal is solid 14k gold as the offer says, understand that lab-grown has little resale value, and keep everything unworn until you are sure, since returns require that.

Price changes

Lab-grown prices fall over time, and offers change. If you see a lower price soon after buying, you can return unworn studs within 30 days and reorder, as long as the policy conditions are met.

Check the certificate

What to do: compare the certificate number and grades with any inscription on the stones, if present, and keep the certificate safe.

Check the stones

Look at the studs in daylight. They should be bright and evenly cut, with secure prongs. Any chips or loose stones should be reported straight away.

Check the metal

Look for a 14k or 585 stamp on the posts or backs. The offer specifies solid gold.

Who sells it

Voss+Agin runs its own online store with over 200 products, including lab-grown diamond and sapphire pieces in solid gold and gold over silver. The page says it is a US company.

Ask about the warranty

The offer page mentions a 30-day money-back guarantee but not a manufacturer warranty. Deal listings for Voss+Agin have mentioned a limited warranty. Ask support what applies to this offer.

Insure them

For a $600 or $900 pair, consider adding them to home contents insurance. Lost studs are a common claim.

Gift receipts

If buying a gift, keep the order confirmation. Returns depend on delivery date, not when the gift is opened, so give the earrings early if the recipient may want to return them.

Pay by card

Paying by credit card adds protection if a refund is refused or the item is not as described.

Keep a photo

Photograph the earrings, box and certificate when they arrive. It helps with insurance and any return dispute.

Read the policy

Read the return policy before buying, especially the unworn condition and the need for a return authorisation number. Following those steps is what keeps the complimentary return free.

Store the certificate safely

Keep the AGI certificate with your receipt and insurance documents. If the earrings are ever lost or stolen, it helps prove what they were.

Push backs

Push backs can loosen over time. Check them regularly, or ask a jeweller about locking backs.

How to buy Voss+Agin the smart way

1. Decide on size and metal, then open the Voss+Agin order page (opens Voss+Agin in a new tab).
2. Compare with the brand store and other lab-grown sellers on the day.
3. Check the certificate and metal stamp on arrival.
4. Keep the box, pouch and documents.
5. Request a return number within 30 days if you are not happy.

How did we score Voss+Agin Diamonds?

Voss+Agin Diamonds scores 5.9 out of 10: claim accuracy 0.9, build durability 1.4, price competitiveness 1.4, usability 1.5 and owner satisfaction 0.7, each out of 2. It earns points for a good specification in solid gold at a low price, with fair returns. Points come off for inflated "retail" prices, oversimplified claims about testers and mining, an unverified US production claim, and no independent ratings.

How the score breaks down

We use the five criteria on our how we test page, each out of 2.

What we did, and did not, do

Nobody on our team has handled these earrings. We read the offer page and return policy on 4 and 5 October 2026, and checked the brand store, FTC guides, price reporting and Trustpilot on 5 October 2026. Our apparel and accessories hub lists other accessories we have reviewed.

How to use and care for Voss+Agin studs

Put earrings on last when dressing, clean them gently with warm soapy water and a soft brush, check the backs regularly, and store them in the box. Remove them for swimming, sport and cleaning with chemicals, and have a jeweller check the prongs once a year.

1. Put them on last, after lotions and hairspray.
2. Check the backs are firmly pushed on.
3. Clean gently with warm soapy water and a soft brush.
4. Dry them with a lint-free cloth.
5. Store them separately in the box.
6. Remove them for swimming and the gym.
7. Check the prongs yearly with a jeweller.

Earring backs for children

If buying for a teenager, consider safety backs or smaller sizes that suit younger ears. Push backs can come loose during sport, and replacing a lost diamond stud is costly even when it is lab-grown, so check the backs carefully before every match or training session, and remove them for contact sports.

Shower and sleep

Many people leave studs in for showers. Soap film can dull the stones, so give them a gentle clean every week or two to keep them sparkling.

Mixing metals

White and yellow gold can be mixed with other jewellery, but people who wear mostly silver or platinum often prefer white gold studs to match.

Annual check

Have a jeweller check the prongs and backs once a year. Tightening a prong costs little; losing a stone costs much more.

Travelling with them

Take them out before flights and store them in their box in hand luggage. Hotel rooms and pools are common places to lose studs.

Swimming and sport

Chlorine can weaken gold over time, and contact sports can knock studs loose. Take them out for swimming, the gym and team sports.

Cleaning tips

Soak them in warm water with a drop of mild washing-up liquid for a few minutes, brush gently behind the stone where oils collect, rinse and dry. Avoid harsh chemicals and ultrasonic cleaners unless a jeweller confirms they are safe.

Sleeping in studs

Some people sleep in studs. Push backs can dig in or loosen at night, so many jewellers suggest taking them out.

Sensitive ears

14k gold contains other metals. Most people tolerate it well, but those with nickel allergies should check the alloy used in white gold.

Other questions about lab-grown studs

Can they be engraved or inscribed? Some lab-grown stones are laser-inscribed with a report number.

Can I upgrade later? The page does not mention trade-ins.

Do they come with a valuation? The certificate grades the stones; an insurance valuation is separate.
