Excellently formed crystals of Pyromorphite (probably arsenious) from the Bunker Hill Mine, Idaho, USA. An important location for Pyromorphite specimens in the recent past, now no longer in production. The Pyromorphite specimen we have displays an intergrown cluster of curving prismatic crystals, the Pyromorphite crystals measure to 1.2cm tall. There is some parallel growth on the prism faces giving the crystals a sparkling finish, with hopper development on the terminations of the crystals. The Pyromorphite crystals are lustrous with a pleasing burnt orange colour.
