Thick botryoidal masses of translucent yellow Austinite over a Limonite matrix. Usually found as thin crusts with crystalline surfaces or small 'gumdrop' formations, this specimen is both unusual and exceptional, easily the best I've ever owned.

Three large, doubly-terminated Amethyst crystals. The crystals are glassy and gemmy with the largest crystal crossing across the top and 9.2cm wide.

Thick, transparent colorless Cerussite crystal, shocking in size and quality for the locality.
