For a 10 ly diamond worth billions of VND, buyers must be extremely cautious. The current market contains many diamonds without GIA certificates, with unclear import origins, or even treated diamonds or sophisticated synthetic diamonds. 

This makes buyers susceptible to major risks regarding actual value, legality, and even resale potential later on. Therefore, when choosing to buy a 10 ly diamond, finding a reputable provider with transparent international certification must always be the top priority.

How many carats is a 10 ly diamond?

In the jewelry industry in Vietnam, “ly” (actually millimeters - mm) is used to describe the diameter of a diamond, while “carat” (ct) is the international standard for measuring weight, with the convention 1 carat = 0.2 grams. These two units cannot be converted directly, but must be based on the cut style and standard proportions.

According to the reference table from the Gemological Institute of America (GIA), a globally reputable grading organization, a 10 ly round diamond (cut according to the Round Brilliant standard) will weigh about 3.5-3.8 carats. This variation is due to different deep or shallow cut proportions, which affect the diamond’s mass.

At Jemmia, we regularly use GIA girdle inscription viewers and Gemolite equipment for comparison, to ensure absolutely transparent and accurate carat and size information for customers. Thanks to this, you can rest assured that the 10 ly diamond you choose always meets international standards and is not overvalued.
