Many people think that diamonds are transparent or white. In fact, most diamonds are a little yellow or brown, and the value of diamonds depends on the degree of colourlessness. The closer they are to colourlessness, the higher their value. According to GIA's identification criteria, they divide diamonds into D to Z grades according to their colour zones. Transparent and colorless: D, E, F Nearly transparent and colourless: G, H, I, J Yellowish: K, l, M Light yellow: N, O, P, Q, R Light yellow: S, T, U, V, W, X, Y, Z
Whether the diamonds are lab-grown or natural, diamonds also have colour grades. The color rating will be subject to the report of GIA or IGI, because it is difficult to accurately select the colour with the naked eye under different light sources.
