Black diamonds are a rare variety of diamond known for their unique black or dark appearance. Unlike traditional diamonds, which are clear, black diamonds are opaque and have a distinctive, deep black color due to internal inclusions or graphite.
These inclusions give them a dark, almost metallic shine. They are often used in jewelry, particularly in bold, modern designs, and are considered a symbol of luxury and rarity.
While natural black diamonds are rare, there are also treated black diamonds that are created through a process that alters the diamond's color.
