Diamond Grading

Diamond Grading is an important part of Northeast Gemological. Diamonds will receive a report based on the 4 C’s; Cut, Clarity, Color and Carat weight. Loose diamonds are weighed on diamond scales that are tested and calibrated daily. Not just opinion or conjecture, Northeast Gemological uses a nationally recognized data base to establish your diamonds value.
