Semseyite (Type Locality)

Item Description

Semseyite is an uncommon lead, antimony sulfosalt, seldom found in well-formed crystal groups such as this. Intergrown, parallel-growth clusters of splendent, metallic-gray semseyite plates form an aesthetic thumbnail from this very well-known locale, which is the Type Locality. This little thumb has excellent form and is pristine in the display view.
