A NOTE FROM NICK A tray of 6 expertly polished highly selected rare Dumortierite standing display pieces with warm dark blue and white colour. This material is super rare. I have only seen this twice in over 30 years. PRODUCT DESCRIPTION Dumortierite from Madagascar Dumortierite from Madagascar, a fibrous aluminium borosilicate mineral known for its blue hues, ranging from sky blue to deep sapphire, with occasional violet or green tinges. Sourced primarily from regions like the Sahatany pegmatites and the Amoron'i Mania area, this mineral forms in slender prismatic crystals or fibrous aggregates within quartz, often accompanied by small pyrite crystals. Dumortierite boasts a vitreous lustre and exceptional clarity, making it a rare and prized gem for collectors. Its unique appearance and limited deposits in Madagascar enhance its appeal as a stunning addition to jewelry or decorative pieces.
