Description

Very aerial crystals that are spread out nicely across the matrix of Albite.

The fact that the latter is white gives a good contrast to the specimen and makes what is a rare, but often not that appealing, mineral into an esthetic specimen.

Former Dr. Francesco Bedognè collection, with label.
