Description

This is a very unusual specimen and a rarity at the same time.
A small find on the Gries Glacier yielded extraordinary siderite. The siderites have a clearly curved shape and have grown together from many individual crystals. The surface is rough due to natural weathering and some crystal surfaces have a lighter-colored secondary mineral. Only a few pieces have been found, the condition is very good. You can be sure of acquiring a truly special piece.
