Carbonado, commonly known as the 'Black Diamond,' is a natural polycrystalline diamond found in alluvial deposits in the Central African Republic and Brazil. Its natural colour is black or dark grey, and it is more porous than other diamonds.Carbonado diamonds are typically pea-sized or larger porous aggregates of many tiny black crystals. The most characteristic carbonados have been found only in the Central African Republic and in Brazil, in neither place associated with kimberlite, the source of typical gem diamonds. Lead isotope analyses have been interpreted as documenting crystallization of carbonados about 3 billion years ago. The carbonados are found in younger sedimentary rocks.
Lovely little stones. They are tiny and it would be nice to see a ruler for comparison, but that is only a suggestion! They are included but as accent stones, I'm sure no one will notice. Love them and can't wait to get more1.5 CTS AUSTRALIAN PINK SAPPHIRE PARCEL [ST9271]
