The Smartest Way to Buy a Certified Loose Diamond in the USA.
Most diamond buyers pay retail store prices — padded with showroom overhead, middleman margins, and markup built on top of markup. Databazaar has sourced directly for over 25 years, which means 1.5 million+ certified stones at up to 50% off what you'd pay elsewhere. Same diamond. Same certificate. Half the price.
100% Certified
Every Stone Is 100% Certified
Every loose diamond ships with a certificate — cut, color, clarity, and carat independently graded. What the certificate says is exactly what you receive. No exceptions, no surprises.
Up to 50% Off
Wholesale Prices. No Showroom Markup.
Direct sourcing built over 25 years means you pay the price the stone is actually worth — not the price that funds a retail jeweler's rent and overheads. The same certified diamond costs up to half elsewhere. Here, it's priced honestly.

Here Is What Buying Smart Looks Like.
The Retail Way
Walk into a jewelry store and pay the price on the tag — which includes showroom rent, sales staff, and margin on top of margin
Limited selection — you see only what that store has in its case, not what's actually available at your budget
Certificates may be GIA, IGI, or in-house — you have to ask, and verify
Pressure-sale environment with upsells, limited return windows, and no price transparency
No ability to compare grades side by side or filter by the 4 Cs at your own pace

For Jewelers & Trade Buyers
You need consistent supply, documented grades, and pricing that works at volume.
Databazaar has supplied jewelers, designers, and trade buyers for over 25 years. With 1.5 million+ certified stones across every spec, you get the depth you need to source without compromise — and the documentation your clients expect.
All diamonds at Databazaar are sold as certified loose stones — ungrouped from any setting, graded independently, and priced on their own merit. This is how serious diamond buyers have always bought.
Once your stone arrives with its certificate, bring it to any jeweler in the USA and have it set exactly the way you want — the metal, the prong style, the ring profile. The certificate travels with the stone.
Buying loose means you get the best price on the stone itself, and full freedom on everything else.
Loose pricing means no jeweler markup is folded into the stone cost. You pay for the diamond — then choose your own setting at whatever price point you want.

Common Questions
Buying a Loose Diamond — What You Need to Know.
A loose diamond is a certified gemstone sold without any setting or jewelry piece. Buying loose gives you the best price on the stone itself and full freedom to have it set exactly how you want — by any jeweler, in any metal, in any style.
Natural diamonds formed in the earth over billions of years under intense pressure. Lab-grown diamonds are produced in controlled conditions that replicate that exact process — they are optically, chemically, and physically identical to natural diamonds. Lab-grown diamonds typically cost significantly less for the same certified grade.
Cut is the most important factor — an Excellent or Very Good cut maximises brilliance regardless of other grades. For color, G–H grades appear white to the eye and offer the best value. For clarity, VS1–VS2 stones are eye-clean at a significantly lower price than IF or VVS. Our filters let you set a budget and surface the best stone within it.
Yes — all loose diamonds come with a 30-day return policy. The stone must be returned in its original unset condition with the certificate. A purchase this significant should never feel like a risk, and we make the return process straightforward.
Yes. Databazaar has supplied jewelers, designers, and trade buyers for over 25 years. If you need melee lots, matched pairs, or consistent bulk supply across a specific specification, contact us directly for wholesale pricing and terms.
Buying loose separates the stone cost from the setting cost, giving you full transparency on both. You pay the actual price of the diamond — not the price of a ring that includes someone else's design margin and setting markup. You then choose your own setting at any price point, from any jeweler you trust.
Select your certified loose diamond, then either use our Build Your Ring tool on site to pair it with a setting, or take the stone to any local jeweler and have it set in your preferred metal and style. The certificate travels with the stone and confirms the grade for whoever sets it.
