Color, clarity, cut and carat weight
The 4C’s of diamonds
Diamonds are one of nature’s greatest miracles. Made of pure carbon and with a hardness of 10 on Mohs Scale, diamonds are the hardest matrial on earth. High gem quality diamonds used in jewelry are rare and are only available in limited quantities. All diamonds are different. Like snowflakes, no diamonds are exactly alike.
GIA created the first, and now globally accepted standard for describing diamonds: Color, Clarity, Cut, and Carat Weight. Diamond value is based on the 4Cs. In combination, these four factors provide a way to discuss diamonds and to compare one diamond to another. Dalby Diamonds is working with the GIA Diamond grading scale and the Scandinavian Diamond Nomenclature (Scan. D.N.) to ensure a clear communication with our clients.
