Black Diamonds , what are they are they real ?.
Like most all colored diamonds, natural black diamonds are extremely rare. They are technically real diamonds filled with dark inclusions (mostly graphite). They appear opaque because of their “polycrystalline” structure which prevents them from reflecting light.
Due to the price of natural black diamonds, most all the black diamonds you see in jewelry stores are treated to enhance their colour, either with irradiation or heat treatment. This process actually turns the natural diamond a very dark green color that appears black.
Is there a difference in quality and price?
The treatment process doesn’t affect durability, but because black diamonds are heavily included and porous, they’re harder to cut and polish. This can result in blemishes and nicks in the surface. When buying black diamonds make sure the surface of them is smooth and polished.
