Description

HERDERITE ON FELDSPAR
Virgem da Lapa, Jequitinhonha Valley, Minas Gerais, Brazil
Rarely seen outside of very sophisticated collections is the rare calcium, beryllium phosphate mineral - Herderite. This is in part due of the rarity of its components as well as its occurrences. The other part of its rarity is the aesthetically challenged nature of most Herderite specimens. The exception to the rule, offered here, features a large (3 3/8 inches!!) (doubly-terminated!!) crystal showing an (attractive!!!!) violet coloration and is on matrix!!!! The statistical odds of such a combination are almost infinitesimally small.

In addition to the outstanding Herderite that is elegantly positioned on a large, light tan Feldspar matrix, there is a small group of dark, blue-green Tourmaline crystals and a spray of white Clevelandite blades. The Herderite is somewhat included but complete, undamaged, and possesses a glassy luster. This is an extremely fine, large and well-formed example of this rare and exotic mineral. The specimen measures 4 ½ inches wide by 2 ½ inches high by 3 inches in depth and comes with a custom labeled acrylic base.

Provenance: Ex. Keith Proctor collection.
