Le Diamond Registry has been setting price scales for buying or selling diamonds since 1961, based on several criteria including diamond weight in carats. Thus, the price of a 3-carat diamond is higher than that of a 1-carat or 2-carat diamond, and this price can vary greatly depending on the diamond's characteristics. If you wish to sell or buy a diamond, it may be helpful to know the price range for a 3-carat diamond in advance.

How to estimate the value of a 3-carat diamond?
To estimate the value of a 3-carat diamond, we rely on several criteria:
Type of diamond
The round brilliant diamond is the most valuable, compared to fancy-shaped diamonds such as pear-cut, cushion-cut, or princess-cut diamonds. Similarly, a set diamond will be more valuable than an investment diamond, i.e., a loose diamond that will not be mounted on a piece of jewelry.
Age of the diamond
The older the diamond (with equal characteristics), the more valuable it is.
Diamond grading report
Above 1 carat, a grading report is highly recommended. This report can be issued by various laboratories worldwide: GIA, HRD, IGI, or LFG. Diamonds certified by GIA are the most valuable. Caution: some laboratories have a poor reputation, and a report from such laboratories will be of little value (for example, AIG).
Diamond characteristics
To determine the diamond's characteristics, we refer to the 4Cs (carat weight, cut, color, clarity). For example, a 3-carat colorless diamond (grade D) with no visible inclusions (IF, VVS1, or VVS2) will be worth much more than a 3-carat diamond with a more tinted color (grades H to K) and inclusions visible to the naked eye (SI1 or SI2): the former costs between $117,000 and $166,000, while the latter costs between $24,000 and $43,000. Fluorescence, symmetry, and polish are other characteristics indicated on the diamond's report and impact the final price.
How much does a 3-carat diamond cost?
The price of a 3-carat diamond ranges from $24,000 (approx. €20,000) to $166,000 (approx. €143,000) or more, depending on the laboratory that certified the diamond, the type of diamond, and its intrinsic characteristics. A 3-carat diamond of color H and clarity VS2 offers good value for money: inclusions are not visible to the naked eye, and the diamond does not appear tinted. The price of such a diamond is around $50,000 (i.e., €43,000).
At Diamantaires Paris OG, you will find a wide range of 3-carat round brilliant diamonds, certified by GIA. Our diamonds are carefully selected for their quality (we prioritize colorless diamonds with no visible inclusions) and we guarantee a broad price range to suit all budgets.

Frequently Asked Questions
Your questions
What is the price of a 3-carat diamond?+
The price of a 3-carat diamond depends on the 4Cs (cut, color, clarity, weight) and its certificate. At this weight, rarity is significant: the price per carat is much higher than for smaller stones. Our gemologists provide a free appraisal to determine its exact value.
Why is a 3-carat diamond worth more than three 1-carat diamonds?+
Because large stones are rare: at equal quality, the price per carat increases with weight. A single 3-carat diamond is therefore worth much more than three 1-carat diamonds combined.
How to sell a 3-carat diamond at the best price?+
Have it appraised by state-certified gemologists who rely on the international Rapaport price list. Diamantaires Paris offers a free appraisal, immediate payment, and a bid-matching guarantee on competing offers.
Is a certificate required for a 3-carat diamond?+
Highly recommended: for a stone of this value, a GIA, IGI, or HRD certificate guarantees the characteristics and maximizes the buyback price. Without a certificate, the appraisal is done on site.
