Description

A unique find of crystallized talc from the Zederhaustal. The beautiful talc crystals display a magical green color. The crystals form leaf-like, hemispherical aggregates, which is unusual for this find, as they typically show feathery crystals. The color is also more intense in this specimen, making the contrast with the whitish dolomite stand out even more.
