There are 3 types of black diamonds, 1)Natural Black (opaque but slightly traslucent) 2)Irradiated (white, transparent, cloudy diamond, I1 to I3 clarity), can be transformed to black (opaque, slightly translucent, green traces when viewed with strong light) and finally 3)Boart diamond (60% of the diamond production). Entire diamond appear black (brownish to acerated hues), completely opaque, zero light can enter to it. From price point of view. Natural Black from 500 per carat, Irradiated Black from 150 per carat, boart heated to black from 50 per carat, so watch carefully what you`re buying.
