Diaspore is an aluminum oxide hydroxide mineral that forms prismatic, often gem-quality crystals. It typically exhibits a color range from colorless to pale yellow or brown, and is known for its adamantine to vitreous lustre. The crystals can occur in compact aggregates or as single, elongated prisms that sometimes show a distinctive zoned or tapered habit, with sharp terminations when well-formed.

About Diaspore

Notable specimens come from regions such as Anatolia in Türkiye, where high-quality diaspore crystals have long attracted collectors, as well as select locations in the United States and South Africa. The best material is often associated with aluminous pegmatites or hydrothermal veins, where clear, well-formed crystals can be found alongside other aluminum minerals. Due to its relatively delicate crystal structure, pristine, undamaged pieces are highly sought after by collectors for cabinet display and as educational references for mineral habit. Diaspore’s rarity in fine form adds to its appeal for those tracking bladed or prismatic specimens with crisp termination faces.
