Faceted Cosmic Obsidian

This nice material has been found in a very small quantity in the volcanic Italian

island: Lipari, near Sicily.

The obsidian from this location is well know since roman’s time, this variety is quite

rare. The small globular inclusions are made of rhyolitic composition,different from

the matrix for a Sodium and Calcium proportion, furthermore some micro crystals

were of  Pyroxene . The result is wonderful.
