10 best online diamond buyers in 2024

If you’re thinking about selling your diamonds or diamond jewelry, you can either sell locally to a jewelry store or pawn shop, or you can choose from a number of reputable online buyers.

Both are good options, but there are a few advantages to selling online:

• Online diamond buyers tend to have many more online reviews (good and bad) that can help you decide where to do business
• Online transactions are more private and can be completed without ever leaving your home
• Online buyers have greater competition and are incentivized to give you the highest payout possible

We put together a list of some of the top online diamond buyers, including pros and cons for each business:

• Abe Mor
• The Alloy Market
• Circa
• Diamond Banc
• DiamondBuyers
• Gemesti

Reviews of 9 online diamond buyers in 2024

The following online diamond buyers are listed alphabetically:

Diamond buyer: Abe Mor

Located in New York City, but doing business everywhere through the company’s website, Abe Mor is a popular and well-known diamond buyer. 

The company has an A+ rating with the Better Business Bureau, and their record has zero customer complaints lodged against it. If you choose to sell your diamond through them, you can rest assured that they are a reputable company.

Like myGemma, formerly WP Diamonds, another diamond buyer leader detailed below, the company specializes in diamond jewelry and luxury resale. In addition to loose diamonds, the company will purchase any branded jewelry or jewelry that contains a diamond of at least 0.5 carats in size.

If your jewelry has smaller stones, or does not contain a diamond, though, Abe Mor will not purchase it. In those cases, our suggestion is to sell with Diamonds USA.

Pros of Abe Mor

• A+ BBB Rating and 0 customer complaints
• Items are insured by FedEx and Brinks for up to $25,000, with additional insurance available if necessary
• Diamond grading reports are not required, though accepted
• Clean, modern, and easy-to-use website
• Relatively quick 2 to 4 day payment upon acceptance of an offer — which can take an additional several days

Cons of Abe Mor

• Like other diamond buyers on this list, their final offer to you is based on a single evaluation (as opposed to an auction of multiple buyers)
• Evaluations are conducted by in-house Abe Mor staff, not third-party lab reports
• Only accepts diamonds at least 0.3 carats in size
• Time from shipment to payment is longer than other sites that promise 24-hour payment. 

The takeaway is that Abe Mor is a reputable diamond buyer with more than 50 years of experience in the industry. Read our full Abe Mor review.

Diamond buyer: The Alloy Market

Alloy is a newcomer to the diamond buying space as of 2023. In that time, the startup has generated some serious media buzz, with coverage from the likes of USA Today, CBS News, and MSN.

While Alloy’s main focus is buying gold, they also accept silver, platinum and palladium, as well as diamond and gemstone jewelry. 

Alloy’s process is similar to other online gold buyers on the market. When we requested a mailer, it arrived the next day. Once you accept an offer, immediate payment is made via Venmo, Paypal, ACH/direct deposit or check by mail, whichever method you choose. 

Pros of Alloy

• A- BBB score (accredited) with 0 complaints
• 4.8/5 stars on Trustpilot 
• Up to $100,000 insurance on every shipment
• Free shipment and returns with no obligation
• Quick turnaround of a week or less if you immediately mail in your items

Cons of Alloy

• Main focus is on metals, not diamonds
• Early promise to launch an app for the sales process has been put on hold indefinitely, according to CEO Brandon Aversano

Diamond buyer: Circa (merged with Mondiamo)

Mondiamo was a relative newcomer to the diamond buyback market, which partnered with BlueNile, a retail leader in the online diamond engagement ring world. 

In early 2020, Mondiamo merged with a competing company, Circa. Circa has maintained Mondiamo’s relationship with BlueNile and has an A+ rating with the BBB.

Circa accepts high-end branded jewelry, as well as diamonds of at least .4 carats, and diamond engagement rings. They will also purchase historical or estate jewelry, including pieces such as: Antique, Edwardian, Georgian, Art Nouveau, Belle Epoque, Art Deco, Retro, Modern.

Circa has 14 physical locations (11 in the U.S. and 3 international), or if you prefer, you can schedule an appointment for an in-person evaluation of your jewelry. Whether in-person or online, if you accept the offer on your loose diamond or diamond ring, you will be paid immediately.

If you provide a grading report from the GIA, EGL, IGI, AGS, GSI, GCAL, IIDGR, or HRD, Circa provides a guaranteed offer range. Once you mail in your jewelry, Circa is able to guarantee a final offer that falls within this range.

The company claims that more than 90% of its customers receive a final offer price higher than the midpoint of the guaranteed range (which includes shipping and insurance). Circa's 15% fee is already calculated into the range.

Circa pros

• Work in partnership with diamond retailer BlueNile, and promise to offer a high fee by cutting out the middleman
• Better Business Bureau rating of A+
• Website's videos and posts create transparency
• Fully insured FedEx delivery — both from you to Circa, as well as returns, when relevant

Circa cons

• They only deal in jewelry with a diamond of at least .4 carats
• If you do not have a lab report, you must send in your item for evaluation and grading before an offer is made
• That offer is good for just 7 days, after which you have to start the whole process over again

In short, Circa is a solid company that brings the BlueNile experience full circle, promising to offer jewelry sellers high prices by removing the middleman.

Diamond buyer: The Diamond Valet

• Straightforward website

Cons of The Diamond Valet

• Just one estimate
• Payment takes longer since they only send paper checks — no PayPal or bank transfer.
• No third-party appraisal. You are at the mercy of the price they offer you.

Diamond buyers FAQs

Here's what you need to know about diamond buyers:

What is a diamond buyer?

A diamond buyer is exactly what it sounds like: A business that purchases loose or mounted diamonds in order to resell those diamonds at a profit. Diamond buyers may resell a stone or piece of diamond jewelry directly to consumers or to industry insiders. While some diamond buyers may operate physical locations (such as a storefront), many of today’s most popular diamond buyers do most of their business online.

What is a diamond exchange?

Most typically, the term diamond exchange is used to refer to a place where diamonds (loose or mounted) can be exchanged — either for cash or, in some cases, trade. 

While the term may have originally been associated with diamond bourses (places where diamonds are traded by industry insiders) this isn’t really the case anymore. Today, the term “diamond exchange” is most synonymous with brick-and-mortar jewelry shops, as evidenced by the number of businesses that weave the term into their name.

How much will buyers pay for diamonds?

A jeweler or other diamond buyer must make a profit on any diamonds purchased, so expect a jeweler to offer you half or less of what you paid for your diamond.

If the stone is an unpopular cut — for example, a marquise shape, or a princess or rose-cut stone — the price may be less than a more popular cut.

This post goes into detail about how to understand the resale value of diamonds.

Diamond resale prices have been on a roller coaster in the past few years.

Prices have fallen nearly 30% since their summer 2022 peak, according to IDEX, which tracks global diamond trends:

Why? 

• Softening U.S. economy 
• Increased popularity in lab diamonds
• Uncertainty in China's diamond-mining market¹

Should I look at diamond buyers only or gold and diamond buyers?

That largely depends on what you have. For instance, if you have gold jewelry that features a diamond or diamond accents, you should get quotes from gold buyers and diamond buyers to see which is willing to offer you more.

Should I sell gold and diamonds separately or together?

Some online diamond buyers will pay you for the value of both your diamonds and gold — you do not need to separate them. Also consider the time involved in seeking out a second buyer. It is likely worthwhile to unload the whole lot with one buyer.

Should I consider selling to private diamond buyers?

When you’re dealing with something as valuable as a diamond, we recommend working with a highly rated and established company rather than a private buyer.  

Before you pull the trigger, research at how long the company has been in business, insurance policies, as well as reviews from sites like the Better Business Bureau and Trustpilot and ask around to friends and family to see if they have any personal experience.

Wouldn't it be better to find a diamond buyer locally.

Every diamond and jewelry buyer has its pros and cons. If you need immediate cash in hand, a local diamond buyer, like a pawn shop or jewelry store, might be your best option. However, in our experience, selling diamonds online will typically result in a higher payout, and many offer quick and insured mail-in services, with payments in 24 hours or less.

Bottom line: Who is the best buyer of diamonds?

Diamonds USA is our top choice online diamond buyer because:

• Pays within 24 hours
• BBB rating of A+
• Pays a 10% bonus if you ship within 7 days
• 100% free and trackable shipment through FedEx — door-to-door
• Insures your item up to $100,000 via Jewelers Mutual en transit, and through Lloyds of London while at their facility
• 100% highest price guarantee
• Buys all diamonds of all sizes and quality

Whether you are selling your gold jewelry, ring, dental fillings, gold coins or silver, Diamonds USA and its sister site, CashforGoldUSA, are quality businesses.

Is Diamonds USA legit?

Diamonds USA is owned by C.J. Environmental, which has an A+ rating with the BBB, and buys all quantities of gold, diamonds, silver and jewelry. Diamonds USA sells to wholesale diamond buyers.

How Diamonds USA works

Diamonds USA operates on a straightforward system. A few years ago, I searched for places to sell diamonds locally, as after my divorce I had a small gold and diamond ring that I no longer wanted.

I checked out Diamonds USA because it has an A+ BBB rating. It was really easy. Here's how it works:

1. I went to the DiamondsUSA website, entered my address, and waited for a mailer to arrive.
2. Two days later I received a USPS mailer in the mail. You can also opt to use a FedEx label, free of charge to me. Your item is insured up to $100,000 through Jeweler's Mutual, and comes with a tracking number.
3. Popped my ring in the mailer, and then the mail.
4. Within a day, I got an email with an offer for my ring. I accepted and within 24 hours received a PayPal deposit for 10% more than I was quoted, as a bonus for shipping within 7 days.

That was my experience, but you can set up the process by email or phone.

Like I did, you can opt for an email offer, which you’ll receive as soon as your diamond is appraised.

You can then accept or reject it online.

Accept, and your check is mailed within 24 hours. Decline, and you’ll get your jewels back with priority shipping.

You can also get a call from the company with your offer. Whether you accept or decline, you’ll get your check or ring back ASAP.
