Diamond Buyback Paris: Get the Best Offer in 2026
You wish to sell your diamond in Paris and get the best price? This guide explains everything: where to sell, how to avoid pitfalls, what your stone is really worth, and why Diamantaires Paris OG offers the best deals on the market.
How much is your diamond worth on the buyback market?
The buyback price of a diamond depends on four main factors: weight (carats), color, clarity, and cut. Added to this is the presence or absence of a GIA certificate, and the condition of the jewelry.
| Weight | Average buyback price | With GIA certificate |
|---|---|---|
| 0.50 carat | €800 – €1,500 | €1,200 – €2,500 |
| 1 carat | €2,500 – €5,000 | €4,000 – €8,000 |
| 2 carats | €8,000 – €18,000 | €12,000 – €25,000 |
| 3 carats and more | From €20,000 | From €30,000 |
These ranges are indicative. The exact value depends on the precise 4Cs of your stone and market prices at the time of sale.
Where to sell your diamond in Paris? Comparison of options
1. Specialized diamond dealers (best option)
A specialized diamond dealer like Diamantaires Paris OG is the solution that generally offers the best price. We know the secondary market perfectly, we have direct buyers, and we don't have to deduct auction house commissions.
2. Auction houses
Christie's, Sotheby's, or Drouot can achieve good prices for exceptional pieces (>5 carats, exceptional quality). But commissions reach 15 to 25%, timelines are long (2 to 6 months), and there is no guarantee of sale.
3. Jewelry stores and gold buyers
To be avoided for valuable diamonds. These shops recover the gold and offer very low prices for the stones, which they then resell to a dealer like us with a significant margin.
4. Online platforms (LeBonCoin, eBay…)
Risky and rarely profitable for valuable pieces. Difficulty in establishing trust, risk of buyer fraud, and ultimately prices not higher than a professional.
What if you don't have a GIA certificate?
You don't have a certificate? No need to worry. Our GIA-certified gemologists analyze your diamond on-site and establish their own grades. This expertise is free and allows us to offer you a fair price even without documentation.
For diamonds over 2 carats without a certificate, we can also arrange to send them to a laboratory (GIA, IGI) for official certification that will increase your selling price. Certification fees are advanced and deducted from the final buyback price.
Our commitment: outbid any competing offer
Have you already received an offer from a competitor? Bring it to us. We contractually commit to offer you better, or to confirm that the offer you have is the best on the market. In any case, you leave with the certainty of having obtained the right price.
