Welcome to SuchenGems!
Black diamonds are rare, valuable, and opaque diamonds that are made of carbon. They are also known as carbonados.
Appearance
Black diamonds have a high luster and opaque appearance
They can appear metallic due to their deep color and shine
They can be black, dark gray, green, or brown
They have an uneven surface, even under magnification
Composition
Black diamonds are made of carbon, graphite, and amorphous carbon
They have natural inclusions of graphite, pyrite, or hematite
Hardness
Black diamonds are very hard and measure a 10 on the Mohs scale of mineral hardness
This makes them difficult to cut and polish
Origin
Black diamonds are found in alluvial deposits in equatorial regions, such as Central Africa and Brazil
Small amounts have also been found in Venezuela and Eastern Australia
