4.2" Polished, Free-Standing Dumortierite With Quartz - Madagascar
This is a 4.2" tall, polished piece of fibrous, blue dumortierite within quartz. Under magnification, the small fibrous dumortierite crystal aggregations can be seen in great detail within the quartz. The base of the specimen has been cut flat so that it displays nicely on a hard surface. It has several patches of gap fill and 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.
