Stibiotantalite
20 in the gallery
Stibiotantalite is a rare mineral composed of SbTaO4. It typically forms in small, elongated crystals or grains with a resinous to sub-metallic luster and a pale to brownish color that can brighten in polished surfaces. Specimens are often associated with granitic and pegmatitic environments, where complex oxides crystallize late in the mineral suite. Notable collections include material from Afghanistan, Mozambique, Myanmar, Pakistan, and parts of the United States, where robust crystal forms and clean separations from host rock are appreciated by collectors.

Where Stibiotantalite is found
About Stibiotantalite
Collectors prize stibiotantalite for its rarity and its role as an indicator of evolved, highly differentiated pegmatite systems. While individual crystals may be modest in size, the mineral’s distinctive composition and the challenge of finding well-formed, lustrous specimens add to its appeal. When displayed, it offers a muted, metallic gleam and a unique color that contrasts with surrounding minerals, making it a compact but striking addition to mineral cabinets and reference collections.
