5) They are said to be cursed

 One of the most famous black diamonds in history has enriched the black diamonds with a mysterious Aura !!! The Orlov black diamond is a wonderful 67 carat black diamond believed to be found in India. Legend has it that the statue of a deity was placed until someone stole the black diamond. In the following years he found himself in the hands of the west, where his owners were plagued by misfortune !!!
The "Brahma's Eye" The "Brahma's Eye" was purchased by a Diamond Dealer in 1932.

6) They are not rated the same way as other diamonds

Because black diamonds are opaque, they cannot be classified on the GIA scale. The GIA does not issue scoring reports for black diamonds. Another thing to note is that black diamonds are denser than white diamonds. So a 1 Ct black diamond will be smaller in size than a 1 Ct white diamond

7) Quality affects the price like all diamonds

4Cs diamond grading applies to black diamonds. Color, purity, cutting and carat weight should be carefully considered if you are buying one. These factors are combined with the International Diamond Certification System (GIA), the standards by which colorless to almost colored gems (D-to-Z diamonds) are rated. Because black diamonds do not fall into this field, their color is based on the GIA classification system for colored diamonds.

Other famous black diamonds include the Gruosi diamond, the African black star and the Spirit of de Grisogono diamond.
