Polished, Free-Standing Dumortierite With Quartz - Madagascar #242860

This is a 3.8" tall, polished piece of fibrous, blue dumortierite within quartz.

The base of the stone has been cut flat so that it displays nicely on a hard surface. In addition to being polished it has also been coated in an epoxy sealant

Dumortierite from Madagascar is typically found in massive form or as inclusions within quartz. When in quartz, it can be identified as blue prismatic or fibrous inclusions that are often mistaken for lazurite or lazulite, neither of which form as fibrous aggregates. Much of the dumortierite from Madagascar seen on the market is included within massive quartz and associated with small pyrite crystals.
