Diamond Buyers in Denver: Expert Appraisal, Top Offer, Paid Today

Looking for diamond buyers near you in Denver? You want a strong offer, a clear explanation and your money without delay. Every stone is graded on-site by our own certified appraiser, in a private office. You see how every part of the offer is worked out, and if you accept, you’re paid the same day, in cash or by wire. No obligation to sell.

Why Sell Your Diamonds to Benadato

Plenty of places will make you an offer, in Denver and online. What matters is who grades the stone, how the number is reached, and whether you can see it happen.

• A diamond dealer, not a counter. Yossi Ben Adato is a second-generation diamond dealer, trading in the U.S. since 2004. We buy loose diamonds and diamond jewelry every day, from a single small stone to a full collection.
• A GIA accredited, on-site. Every diamond is graded in-house during the same visit, by Michael Nedler, GIA accredited since 1981, and by Yossi, with a Sarin scan when needed. The 4Cs, the certificate, the setting and any designer name are each priced on their own line.
• The math, explained. You get an itemized offer and we walk you through exactly how we reach the number, so there are no surprises. Have a written offer from another buyer? Bring it and we’ll do our best to beat it.
• Paid the same day. Accept the offer and you’re paid before you leave, by wire, Zelle, Venmo, check or cash. No waiting for a resale, and no auction fees.

What Is Your Diamond Worth?

Expect less than the price on the original receipt. Retail prices include the jeweler’s markup, marketing and store costs, and none of that carries over when a diamond is resold. What does carry over is the stone itself and, in some cases, the setting and the name on the box. Here’s what sets the price.

1. The 4Cs

Carat, cut, color and clarity make up most of a diamond’s value. A single step in color or clarity can move the offer more than most people expect. We’ll be straight with you: loose natural diamonds under 1.5 carats have lost a lot of resale value since lab-grown diamonds entered the market, while larger, well-certified stones hold their value far better. For a closer look, see how much is my diamond worth.

2. The Certificate

We buy diamonds with any certificate, or none at all. For natural diamonds, a GIA report usually earns the strongest offer because it’s the industry’s most trusted standard. You can check your GIA report online before you visit. With any lab, we verify the grading ourselves and our offer reflects what we see. Selling a diamond with a GIA report? See how we buy GIA certified diamonds. No certificate? Michael Nedler, our GIA accredited, grades the stone during your visit, so there’s no waiting on an outside lab.

3. Natural or Lab-Grown

Lab-grown diamonds have very little resale value today, because new ones keep getting cheaper to produce. In most cases the gold or platinum setting is worth more than the stone. We test every stone for free and tell you exactly what it is before we talk numbers. Read more in can you sell lab-grown diamonds.

4. Fancy Colors

Fancy colored diamonds are one of our specialties. They’re priced mainly on the intensity and purity of the color, so a GIA colored diamond report makes a big difference. Rare natural pinks, including Argyle pinks, and fancy vivid yellow diamonds can be worth far more than white diamonds of the same size. We’ll tell you whether the color is natural or treated, and Yossi and Michael Nedler, our GIA accredited, evaluate every colored stone personally. See also black diamond buyers.

5. The Setting

Platinum and gold are weighed and tested, and small side diamonds add value, though far less per carat than a center stone. Rings from houses like Tiffany & Co. and Cartier can be worth more than their materials when they’re authentic.

6. Condition

Chips and abrasions lower a diamond’s value. There’s no need to clean, repair or remove stones before you come in.

Where to Sell Diamonds Near Me, and Where Not To

Each option pays differently and carries different risks. Here’s an honest comparison.

Before You Sell Your Diamonds: 6 Things Worth Knowing

1. Find the paperwork. A GIA report, receipt or original box isn’t required, but it can raise the offer.
2. Don’t remove stones from their settings. Bring each piece as it is. Taking stones out yourself risks damage.
3. Know natural from lab-grown. It’s the biggest single difference in resale value. Not sure? We’ll test it.
4. Ask for an itemized offer. Each stone, the metal and the brand should each have a number.
5. Keep your diamonds in sight. A buyer you can trust grades and tests them in front of you.
6. Compare cash to cash. A trade-in credit or an auction estimate isn’t the same as money paid today.

Brittany Garciaa week ago

I had a wonderful experience at Benadato Trading Co. Yossi was friendly, professional, and very knowledgeable. Previously, I took some jewelry to a jewelry store and received a bid. I gave Yossi the same items, and his bid was higher, thus demonstrating his honesty. Not only did I feel comfortable the entire time I was there, It was an enjoyable and memorable experience. Highest rating.

Beverly Milder Magenceya week ago

Absolutely phenomenal service. The entire process was professional to a degree that you feel when you are shopping in couture stores. Yossi and his staff all introduced themselves, I felt comfortable, respected, and the offer was beyond what I even expected to receive.
Tip: go to the elevator inside and go to the 5th floor!

Diamond Selling FAQs

Where is the best place to sell diamonds near me?

Directly to a diamond buyer who grades the stone in front of you. Retail jewelers pay less because they resell at a markup, pawn shops price for risk, and marketplaces leave you dealing with strangers. We appraise, price and buy in-house, so there’s no middleman taking a cut.

Who buys diamonds near me?

Diamond buyers, jewelers, pawn shops and online buyers all buy diamonds, but they pay very differently. A diamond buyer who grades the stone in front of you usually pays the most, the same day. Benadato buys loose diamonds and diamond jewelry of every brand at our Denver office, and by insured mail from anywhere in the world.

How much is a 1 carat diamond worth to sell?

It depends on cut, color, clarity and certification, but we’ll be straight with you: loose natural diamonds under 1.5 carats have lost a lot of resale value since lab-grown diamonds entered the market. Larger, well-certified stones hold their value far better. Recently we paid $2,500 for a 1.5 ct cushion, $17,000 for a 3 ct round and $20,000 for a 2.5 ct radiant. The fastest way to know is a free evaluation, with a Sarin scan when needed.

Why are diamonds hard to resell?

Retail prices include the jeweler’s design, marketing, rent and profit, so what you paid in a store is always well above wholesale. A buyer can only pay close to the wholesale value, and lab-grown diamonds have pushed wholesale prices for smaller natural stones lower. We walk you through exactly how we reach our number, so there are no surprises.

Do you buy colored diamonds, like pink or yellow?

Yes, and they’re one of our specialties. Fancy colored diamonds are priced mainly on the intensity and purity of the color, so a GIA colored diamond report makes a big difference. Rare natural pinks, including Argyle pinks, and fancy vivid yellow diamonds can be worth far more than white diamonds of the same size. Yossi and Michael Nedler, our GIA accredited, evaluate every colored stone personally.

Do you buy diamonds with IGI or other non-GIA certificates?

Yes. We buy diamonds with any certificate, or none at all. For natural diamonds, a GIA report usually earns the strongest offer because it’s the industry’s most trusted standard. With any lab, we verify the grading ourselves and our offer reflects what we see.

Do you buy small diamonds?

Small diamonds on their own usually have little resale value, so we focus on larger diamonds and gemstones, where we can be much more competitive. If your small diamonds are set in gold or platinum jewelry, bring the piece in and we’ll pay for the metal and a bit extra for the diamonds.

Do you buy lab-grown diamonds? Do they have resale value?

We’ll always take a look, but here’s the honest answer: lab-grown diamonds have very little resale value today, because new ones keep getting cheaper to produce. In most cases, the gold or platinum setting is worth more than the stone. We’ll test it for free and tell you exactly what it is.

How can I sell my diamond for the most money?

Five things make the biggest difference. Make sure your diamond has a GIA grading report, and keep the original copy. Know whether its quality is in demand: an I2 clarity stone is a hard sell when lab-grown diamonds offer a cleaner-looking alternative. Keep the diamond in perfect condition, because diamonds can chip and break, and repolishing means an expensive, lengthy process that includes regrading by GIA. Understand market trends: fashion drives demand toward certain shapes, and a square stone sells differently when the market is moving toward elongated shapes. And work with a knowledgeable trading partner, not a gold chop shop. If you only get a number with no explanation, keep shopping.

Do you buy sapphires, rubies and emeralds?

Yes. We buy fine colored gemstones, loose or set. Size, color, origin and whether a stone has been treated all affect value, so a report from a respected lab such as GIA, AGL or Gübelin makes a big difference. Yossi and Michael Nedler, our GIA accredited, evaluate every gemstone personally.

Do you buy diamonds without a certificate?

Yes. Most diamonds we buy arrive without one. Michael Nedler, our GIA accredited, grades each stone with professional equipment during your visit. You’re also welcome to bring an independent appraisal, and we’ll explain how it compares to ours.

How do I get paid?

The same day you accept, by wire, Zelle, Venmo, check or cash. There’s no limit: we’ve paid from a few hundred dollars to seven figures for the right piece.

Can I sell my diamonds online?

Yes. We buy from anywhere in the world and ship items daily. Contact us for a shipping manifest and an insured FedEx label. Once your package arrives, we’ll call you with an offer within 1 to 2 business days and pay the same day you accept. See how to ship your items safely.

Will my sale stay private?

Yes. We meet with one client at a time in our private Cherry Creek office, and your visit and your items stay confidential.

What types of diamonds do you buy?

Loose diamonds and diamond jewelry of every kind: engagement rings, wedding bands, earrings, bracelets, necklaces and pendants, in any shape, with or without a certificate. Larger natural stones earn our most competitive offers, and fancy colored diamonds are a specialty.

How much is my diamond jewelry worth?

Four things set the number: the diamond itself (carat, cut, color and clarity), the setting (the weight and purity of the gold or platinum), the maker (a signed Tiffany or Cartier piece is valued as jewelry, not as parts) and the condition. We price each on its own line, so you see what the stone is worth, what the metal is worth and what the brand adds.

Is a certified diamond worth more than an uncertified one?

Usually, yes. A GIA report confirms the grades, so a buyer can price the stone with confidence and pay closer to its full value. An uncertified diamond isn’t worth less by nature, but it has to be graded first, which we do in front of you at no charge. A large stone with no report can still earn a strong offer; the report mainly removes the guesswork.

Is the offer negotiable?

We lead with our best number rather than a low opener, and we show you how we reached it: the grades, the spot price for the metal and the current resale market. If you have an independent appraisal or a competing offer, bring it. We’ll walk through the differences with you and tell you honestly where we can move and where we can’t.

What paperwork do I need to sell my diamond?

None is required. If you have a GIA or other lab report, an insurance appraisal or the original receipt, bring them: they can raise the offer and speed things up. Lost the report? If the stone is laser inscribed we can often look it up by its number. If not, Michael Nedler grades it during your visit.

What should I ask before selling my diamond?

Ask who is grading the stone and what their qualifications are, whether the evaluation is free and without obligation, how the offer is calculated, whether there are fees or commissions, how and when you get paid, and whether you can take the stone home to think it over. A buyer who answers all six clearly is worth talking to. At Benadato the answers are: a GIA accredited, free, shown to you line by line, none, the same day by wire, Zelle, Venmo, check or cash, and yes.
