Amethyst, Veracruz, Mexico; 10" across

This is an elite specimen of amethyst. It was formerly in the collection of Karl Kempf. described him as "Intel's Money Saving Mathematician". I bought this piece from Wayne Thompson in 2006 after it was released from the Kempf collection. The amethyst plate was also pictured in a "Matthew Webb" advertisement that appeared in "The Mineralogical Record" during 2010.


Other fine quality amethysts specimens depicted on this Webb-site are from Artigas, Uruguay; Goboboseb, Namibia; Magaliesburg, South Africa; Karur, India and some localities in the Australian outback.  Other important amethyst producing localities including Brandberg, Namibia; Guerrero, Mexico; Jacksons Crossroads, Georgia and near Santa Cruz, Bolivia where quartz with purple and citrine colored phases occurred.  This gemmological oddity is referred to as "Ametrine."
