Quartz with Dravite-Schorl, Siderite
specimen number:
8036252
location:
Panasqueira Mine, Covilha, Castelo Branco, Portugal
description:
Extremely fine large cabinet example from this classic locality with glassy absolute gem colorless crystals of quartz to 7.0 cm in size forming a matrix less cluster and partially coated with needlelike black crystals of dravite-schorl. Minor siderite present as well. This sits perfectly by itself or display that has no points of attachment and is beautifully crystallized all around. I think in super condition.
