描述

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
