How much does 1 carat of diamond cost in dollars?

How to compare diamond prices correctly? The price of each individual diamond is made up of many factors, for example, diamonds with the same clarity rating (eg SI1) but with different types of inclusions will have different prices. In the same way with the color of a diamond, for example, color 5 (H) according to standards can have a yellowish, lilac, gray or brown tint. The last shade (brown) significantly reduces the price of the diamond. This is explained by the fact that with the same intensity of brown and, for example, yellow, the brown color is perceived by the human eye as darker. There are even more nuances in the quality of cutting, symmetry, and polishing. Therefore, it is not so easy to compare diamonds. For a superficial comparison, you first need to make sure that the diamonds were certified by the same laboratory. This is extremely important, because the characteristics indicated in the certificates of commercial laboratories (primarily EGL, IDL, IGL and others) are several orders of magnitude higher than the reference (real) assessment of the Gemological Institute of America (GIA). It is impossible to guess how high the characteristics are in this case, therefore, the comparison will be extremely inaccurate. You can read more about commercial certificates in the “Certificates of Commercial Laboratories” section. If the certificates are similar, weight, color, clarity are also of the same order, it is necessary to check the quality of cut, polishing and symmetry. The price difference between excellent cutting and polishing quality (Excellent) and good quality (Good) reaches 30%. The last important point affecting the price is fluorescence. The highest level of fluorescence – Very Strong Blue – also reduces the price of the diamond by 5-10%.

The presented diamond prices round cut grade A – approximate and may vary depending on the Rapaport price list. Prices are current as of June 2024. Diamonds weighing up to 0.2 carats are sold only in lots (from 2 carats). Diamonds weighing more than 0.3 carats are accompanied by a certificate GIA (Gemological Institute of America). To more accurately calculate cost of diamonds, use our calculator or diamond selection wizard. The terms of use of the calculator and selection wizard can be found on this page.

From us you can buy diamonds for engagement rings, studs and pendants. Our prices for diamonds can satisfy any buyer. We offer certified diamonds ranging from 0.30 to 2.00 carats with grades ranging from 2/2 and below.

We cooperate with the largest cutting enterprises in Russia, so we always have a large selection of stones. All diamonds undergo mandatory certification (who certifies diamonds in Russia). If, at the moment, there is no diamond with the specified characteristics, we can order such a diamond at the factory and provide it to you as soon as possible (reference information about diamonds).

Below is a table of the cost of diamonds, divided by weight group. Using it you can calculate the final cost of the diamond.

The diamond cost table is indicated in US dollars per carat (international practice). The color is indicated vertically, the quality in numbers is indicated horizontally (Russian system for assessing the quality of diamonds) (See the table of correspondence between the international characteristics of GIA and TU diamonds here). To calculate the cost, you need to select a table with the appropriate weight range. Find the intersection with the given parameters of color and quality, and multiply the found figure by the weight in carats.

For example, to calculate the cost of a diamond weighing 0.35 carats with characteristics 4/5 (table of the dependence of diamond weight on diameter), you need to use the table for the range 0.30-0.39, find the intersection of color 4 (vertical) and quality 5 (horizontal) (3366 US dollar per carat) and multiply the resulting number by 0.35, i.e. 3366×0.35=1178 US dollars. Since such a stone falls in the range of 0.35-0.39, another 5% is added to this cost. As a result, this certified diamond will cost 3366×0.35=1178+5%=1237 US dollars. The price of the diamond includes VAT. Conversion is carried out into rubles at the Central Bank rate + 2%.

Diamond cost table.

Prices are indicated for diamonds with a cut no worse than group A (Very Good) and moderate fluorescence. Prices are indicated in US dollars per carat, including VAT 18%. (Practice of wholesale companies). If the cut quality is upgraded to “Excellent”, the cost increases by 5%. In the absence of fluorescence by 3%.
