- Miniature, 3.7 x 2.8 x 2.5 cm
- Xanda Mine, Virgem da Lapa, Minas Gerais, Brazil
- Ex. Dr. Stephen Smale
In the late 1970's a marvelous find of gem minerals was made at Virgem da Lapa, including the world's finest herderites. This specimen features a 2.6 cm long, translucent, blue- gray, gemmy and lustrous herderite with tiny green elbaites and pink lepidolite crystals. It is a very attractive miniature and has a definitively more blue hue to it than the generally purplish ones for which the mine is famous. It is complete all around save for a few very trivial contacts. He got it in Brazil himself, while teaching math in Rio.
