Hureaulite

Hureaulite is named after its discovery locality, at the Huréaux quarry, St-Sylvestre, 21 km north of Limoges, Haute-Vienne, France.

Hureaulite forms transparent to translucent light rose to pink to rose-violet, orange or yellowish brown long to short prismatic elongated crystals with vitreous to greasy lustre.

Hureaulite gems are usually translucent and moderately included. Therefore faceted stones are very rare. Hureaulite can be used as ornamental material.
