FAQs
Are Black Diamonds genuine?
Yes, they are real diamonds. Their dark appearance is typically caused by natural inclusions, while some may be treated to achieve an even black tone.

What cuts are available?
Choose from traditional cuts such as round, oval, and emerald, along with fancy shapes like cushion, pear, trillion, and heart. Cabochon cuts are also offered for bold designs.
Are Black Diamonds valuable?
