An excellent and very rich specimen covered with sharp, glassy and partially gemmy, burnished brown pyrochlore octahedrons, with flashes of gemmy red fire, aesthetically covering matrix on this very fine specimen from Vishnovogorsk, Ural Mts., Russia. Pyrochlore is an uncommon niobium oxide and crystals are usually brown and dull and earthy. Lustrous, glassy crystals such as these, with a rich lively brown color, are quite uncommon and this locality is regarded as the king for "pretty" examples of the species. Most came out in the 1980s or before, I was once told, and were released from old stashes.
