From this classic locality for the species belongs this group of thoryanite crystals, cubic with octahedral shapes at the vertices, twinned and interpenetrated, good size, intense black color, and luster. Thorianite is a thorium oxide, almost always containing some uranium, the variety being uranothorianite.

From this classic locality for the species belongs this group of thoryanite crystals, cubic with octahedral shapes at the vertices, good size, intense black color, and luster. Thorianite is a thorium oxide, almost always containing some uranium, the variety being uranothorianite. This specimen contains around 5-6% uranium by weight. An exceptional piece due to its richness.

The titanite crystals from this Malagasy locality are largely unknown to collectors. They are a group of very good-sized crystals with defined faces and a brownish color, set within a matrix of calcite, scapolite, and diopside. A very interesting specimen, both for its location and for the unusual size and shape of the titanite. It was identified as coming from Fort Dauphin. The Amboasary district is famous for its numerous deposits of thorianite and phlogopite.
