Set of 11 diamond colour-grading stones by Gemoro Resolution_0.01g bright lightDetails The only way to colour grade diamonds is to match the colours against carefully graded samples. Here are 11 carefully colour graded stones, 1. 00ct each, colours D to N. This set is unique in that it has 11 stones, and also because it has a built in UV light (with a USB rechargeable battery). Please note, these are colour grading stones for diamonds, they are not diamonds (they are Cz).
