A very rich miniature specimen consisting of aggregates of bladed Franckeite crystals, a rare iron-lead-tin-antimony sulfosalt. The San José mine, Bolivia, has produced some of the world's best crystallized specimens and this specimen is no exception. Specimens from this mine are never large, but then neither are crystals of this rare species. Excellent crystals of metallic grey to silvery grey Franckeite form intergrown radial platy crystal aggregates covering all sides of the specimen. A very fine Franckeite specimen displaying the typical crystal form very well.
