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).
