Adamant Gems

Adamant Gems is a family business with more than 20 years combined experience in the diamond industry.  We are a pair of two, both with Graduate Diamond certifications from GIA (the most respected Gemological Lab In the World).
We take pride in educating our customers so they can make educated decisions when purchasing a diamond.  We only deal with top quality stones that have been graded from GIA (Gemological Institute of America). GIA grading reports revolutionized the diamond industry in 1955 with its Diamond Grading Report.

Based on the 4Cs of diamonds and International Diamond Grading System™, both of which GIA created, the grading report provides a comprehensive analysis of quality and authenticity for diamonds in the D-to-Z color range. It contains information on diamond shape and cutting style, measurements and weight, proportions and finish along with grades for clarity, color, and cut.

In addition, it identifies any known treatments. While a number of laboratories issue similar reports, the GIA Diamond Grading Report has earned a reputation for unrivaled accuracy and integrity when assigning diamond grades.
