For a 10mm diamond worth billions of VND, buyers must be extremely cautious. The current market contains many diamonds without GIA certificates, unclear import origins, or even treated or sophisticated synthetic diamonds.
This can lead buyers to face significant risks regarding true value, legal status, and future resale potential. Therefore, when choosing to buy a 10mm diamond, finding a reputable unit with transparent international certification must always be a top priority.

Let's join diamond expert Kiệt Hột Xoàn in evaluating diamond quality using equipment directly imported from GIA - the Gemological Institute of America:
How many carats is a 10mm diamond?
In Vietnam's jewelry industry, "ly" (actually millimeter - mm) is used to describe the diameter of a diamond, while "carat" (ct) is the international standard for measuring weight, with the convention that 1 carat = 0.2 grams. These two units cannot be directly converted; it requires considering the cut style and standard proportions.
According to reference charts from the Gemological Institute of America (GIA), a globally reputable appraisal organization, a 10mm round diamond (cut in the Round Brilliant standard) will weigh approximately 3.5-3.8 carats. This variation is due to different cut depths or shallowness, affecting the diamond's weight.
At Jemmia, we regularly use GIA laser inscription scanners and Gemolite equipment for cross-referencing, ensuring absolute transparency and accuracy of carat and size information for our customers. Thanks to this, you can be assured that the 10mm diamond you choose always meets international standards and its value is not exaggerated.
