Copper (Spinel twins) with Analcime

0 for sale·Member since 2026
This is a wonderful miniature composed of interlocking spinel-law twinned copper crystals. The twinned crystals are unusually sharp for Michigan and have a perfect patina. The white balls are not calcite as you would expect, but analcime crystals scattered on the surface of the specimen.
