Our customer education center is an invaluable way for our clients and correspondents to learn about the 4 C’s of the diamond market and how they pertain to valuing colored diamonds. We pride ourselves in providing up to date information on the activity in the market at the auction, retail and dealer level while at the same time helping our clients understand the subtle nuances in the grading standards of colored diamonds to ensure they are acquiring the rarest and most sought-after pieces in the market. This includes our reports on grading standards of different color categories and shapes as well as the courses the American Institute of Diamond Cutting teaches to hundreds of students from around the globe.
