A superb example of this rare color and variety of Herderite.  The limited find of this material occurred several years ago near Ouro Verde in the state of Minas Gerais.  This find and the stones that came from it were written up in the Spring 2004 issue of Gems and Gemology.  The color is excellent, even a bit more green than in the photo, the cutting excellent and the stone is clean.  An excellent example of a gem with very limited availability.
