Yes, Diamonds come in various colours ranging from blue, white to black. Diamonds are colour graded on the G.I.A (Gemmological Institute of America) Scale. The closer the diamond is to having no colour, the more rare and valuable it is and therefore the more expensive. The best grade is colour “D†, which has no trace of colour.
