Cassiterite with Quartz, Siderite, Pyrite
specimen number:
8121578
location:
Panasqueira mines, Beira Baixa, Portugal
description:
Wonderful large cabinet piece with lustrous crystals of cassiterite to 1.2 cm in size up on this large grouping of gemmy glassy colorless quartz crystals. Pyrite present as well. This is in terrific condition with the most minimal and sparse micro-chipping present, I don't think you could ask for it to be in any better condition. Shows well all around and displays nicely on its own. Minor siderite present as well.
Size: 19.0 x 12.0 x 12.0 cm (large-cabinet)
