As a unit showing the weight of diamond, 1 carat equals 0.20g.
The term “carat” is derived from the carob tree.
The fruit of the carob is almost uniform in weight when dried, which made it ideal for use as a unit by which to measure the weight of jewelry in ancient times.
This shows the colors of diamonds.
Taking the master stone regulations of GIA (Gemological Institute of America) as a standard, diamonds are split into 23 grades from D to Z, and in general the closer to colorless the diamonds are, the higher their class.
Diamonds are composed of pure carbon (N), but yellowing occurs due to the inclusion of nitrogen (C) impurities in the carbon.
Assessment of this yellowing characteristic is shown in grades from D to Z, and yellowing becomes stronger as the grade moves away from colorless D and closer to Z.
This shows the clarity of diamonds.
Class is determined by the number, size and location of inclusions and blemishes found in diamonds.
Diamonds are classed according to 11 grades, from FL that have absolutely no inclusions to I3, where inclusions are visible to the naked eye, based on the classes established by the GIA (Gemological Institute of America).
This determines the brilliance of our diamonds.
Cuts where symmetry and balance are definite components have a significant influence on the beauty of diamonds.
We inspect symmetry and the polish of each facet in our pursuit of ideal proportions, and classes are determined in line with the strict standards of the GIA (Gemological Institute of America).
