At first glance, most colorless diamonds look like twin brothers. And this is not so much due to the unprofessionalism of the beholder as to the imperfection of human vision. Therefore, when choosing a single stone or diamond jewelry, it is necessary to carefully read the characteristics on the product tag or in the certificate. For example, they say that the color and clarity of a diamond correspond to 3/3. What do these numbers mean for the buyer?
Deciphering
There are several systems of diamond certification in the world. In our country, TU 117-4.2009-2002 is accepted. To evaluate a stone, jewelers use a special table. Stones weighing up to 0.29 carats have 7 grades of color and 9 grades of clarity, while stones weighing from 0.3 carats have 17 grades of color and 13 grades of clarity. There is also a difference in the grading of stones with 17, 33 and 57 facets. But below we will consider only round brilliant-cut diamonds with 57 facets, since such stones are the most common.

Stones up to 0.29 carats
Thus, when it comes to a 57 facet diamond (the most popular cut type) weighing up to 0.29 carats, the color and clarity of which correspond to the parameters 3/3, it means that:
Diamonds over 0.3 carats
For stones weighing 0.3 carats or more, a 3/3 (color – 3, clarity – 3) means that:
GIA values
GIA is an international diamond certification system developed by the Gemological Institute of America. Its certificates are recognized worldwide. A diamond with color 3 and clarity 3 according to the Russian TU system corresponds to the following classes in the GIA system.
Stones up to 0.29 carats and characteristics 3/3
Have color G, H or I, which means a white stone without tint, and purity VVS1 or VVS2 (Very Very Slightly Included) in the GIA system. This clarity means that inclusions can only be seen through a microscope.
Diamonds over 0.3 carats and 3/3 characteristics
In terms of color, they correspond to GIA grades E or F, which means colorless stones, and VVS1 or VVS2 (Very Very Slightly Included).
Verdict: Buy
A diamond with 3/3 characteristics is a great buy. It will be perfect both as a jewelry piece and as an investment object. However, the latter makes sense only for stones weighing 1 carat or more. We told you more about “precious” investments here.
