Calcite var. Iceland spar (Type Locality)

Item Description

Calcite "Iceland spar" from the Type Locality is among the finest examples in the world and this is a most impressive cleavage rhomb. The rhomb is stunningly water-clear, colorless and looks like a cut stone. The optical-grade calcite has typical double refraction. The very few internal planes add pizzazz to this classic calcite. Classic older material from an East Coast collection.
