This specimen features sharp, metallic, lustrous crystals to 1.6 cm embedded in contrasting quartz matrix. Note also the several clusters of smaller, but extremely fine and freestanding crystals elsewhere on the specimen. It is a DRAMATIC display specimen of the classic old erythrite from this silver-mining district that, until recent days, was by far and away among the world's best for the species for hundreds of years! Such pieces, especially in this size, are almost unavailable and come up only in a few choice old collections. 9 x 8 x 5.5 cm
