What is a 3.5mm diamond, and how many carats is it?
A 3.5mm diamond is a common term used in Vietnam to refer to the diameter of a diamond measured in millimeters. "3.5 ly" means the diamond has a diameter of approximately 3.5mm.
In the international jewelry industry, diamond sizes are usually converted to carats (ct) - the standard measure for weight. With standard proportions, a round brilliant cut diamond with a diameter of 3.5mm will weigh approximately 0.15 carats (ranging from 0.145-0.16ct depending on depth and cut proportions).
This means: 3.5mm is equivalent to approximately 0.15 carats.
Understanding the conversion from millimeters to carats helps buyers easily compare prices and check information in GIA grading reports or other reputable certificates.
