- Cabinet, 13.0 x 5.1 x 4.1 cm
- Golconda Mine, Governador Valadares, Minas Gerais, Brazil
A matrix shard of feldspar, richly covered with pearlescent and translucent, tabular and doubly-terminated, crystals of ghostly white bertrandite to 4 cm in length, aesthetically perched high on a massive matrix of the what seems to be rough feldspar. VERY few good matrix specimens were found in this pocket, and this is one of the best larger ones without damage. These are enormously significant crystals for the species, and this is a cabinet sized display specimen worthy of any museum.
