Gemstone of the Week: Phosphophyllite

(Phosphophyllite sample from irocks.com)

Phosphophyllite is a beautiful and very rare blue-green to colourless gemstone.  It is a hydrated zinc phosphate and is named from the Greek word for "leaf" (phyllon) and from it being a phosphate based gem.  The ''leaf" portion of its name is because of the way the stone cleaves (breaks).  Phosphophyllite may be found in Germany, the state of New Hampshire, and Bolivia, but some of the best samples come from Bolivia.
