Established in 1931, The Gemological Institute of America (GIA) is the world’s foremost authority on diamonds, colored stones, and pearls. A public benefit, nonprofit institute, GIA is the leading source of knowledge, standards, and education in gems and jewelry.
In the 1940s, GIA established the “4Cs” : CUT, CLARITY, COLOR, CARAT WEIGHT and the International Diamond Grading System™ – to this day, the worldwide standard for evaluating diamond quality.
The sparkle and brilliance of a diamond depends more on its cut than anything else.
The absence of inclusions and blemishes makes a diamond rare and affects value.
Diamonds in the D-to-Z color range are valued by how closely they approach colorlessness – the less color, the higher their value.
Diamonds and gemstones are weighed in metric carats: one carat is equal to 0.2 grams, about the weight of a paperclip.
At DK Gems International we are proud to be part of this Institution.
