Here is a very interesting PBS article on carbonados. http://www.pbs.org/wgbh/nova/diamond/sky2.html
Steve Schoner IMCA #4470. P.S. I have a 21.55 ct carbonado from Brazil, and it is one of the most interesting pieces in my collection. It is amazing what it feels like to hold it. It is waxy to the touch, and feels cold to the touch. This latter property is due to the fact that all diamonds conduct heat as readily as pure copper. But under the microscope the porous structure that is the prime characteristic of a true carbonado is very obvious. Not all black diamonds are carbonados, though the term "carbonado" is used loosely to describe low grade diamonds in the diamond trade. ____________________________________________________________ Click here for free information on how to reduce your debt by filing for bankruptcy. http://thirdpartyoffers.mybluelight.com/TGL2341/fc/BLSrjpdl0IoTK1URErUnkyUHaViM5qtgOUmDfKqXxOtSe1N9XftiVS0OsGM/ ______________________________________________ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
