Hi Frank and List, >From the description in the article, the diamonds sound like carbonado types. The De Beers cartel has nothing to worry about, because that kind of diamond is not going to be in high demand on jewelry and wedding rings. However, this could radically alter the industrial diamond market.
I've owned some larger carbonados and examined them under magnifications up to 1200x. They are very strange and unlike anything I have ever seen. Looking at smaller broken pieces under the same magnifications reveals an alien landscape of crevasses and jagged crystalline peaks and valleys. I don't have a polarizing setup, so I don't know what a thin section would look like. 2 questions : Has anyone ever made a thin section from such diamonds? And if so, can someone post a photo of the view in cross-polarized light? For those who are interested, I have some nice carbonado fragments - http://www.galactic-stone.com/product/carbonado-black-diamond-ancient-impact-artifact Best regards, MikeG -- ------------------------------------------------------------- Web - http://www.galactic-stone.com Facebook - http://www.facebook.com/galacticstone Twitter - http://twitter.com/GalacticStone Pinterest - http://pinterest.com/galacticstone RSS - http://www.galactic-stone.com/rss/126516 ------------------------------------------------------------- On 9/17/12, Frank Cressy <[email protected]> wrote: > Thought this might be of interest. > > Frank > > http://news.yahoo.com/russia-reveals-shiny-state-secret-awash-diamonds-131212873.html > > ______________________________________________ > > Visit the Archives at > http://www.meteoritecentral.com/mailing-list-archives.html > Meteorite-list mailing list > [email protected] > http://six.pairlist.net/mailman/listinfo/meteorite-list > ______________________________________________ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
