Naturally black diamonds are extremely rare but their demand is very high, thus natural real diamonds are often treated to obtain charcoal colored fancy black diamonds. Heat treatment, HTHP or irradiation are the common treatments used to enhance or correct the color of the diamonds. Discover the largest collection of loose treated black diamonds here at Instagem.
