In 1801, Diaspore was first discovered in the Ural mountains of Russia. After its discovery, it was named "Diaspore" from the Greek word "diaspeíreif" which means to "scatter". This name was given by René Just Haüy, a French priest and mineralogist, in allusion to the mineral's decrepitation on heating. The type locality of this mineral is Mramorskii Zavod (Mramorsk Zavod), Kosoi Brod Village, Polevskoy, Sverdlovsk Oblast, Russia.

Formation Process

Diaspore typically occurs as a result of diagenesis in bauxite formed by the tropical weathering of alumino-silicate rocks. It also occurs in some alkalic pegmatites as a hydrothermal veins, clay deposits and limestones, and nepheline syenite pegmatites.


The chemical formula of Diaspore is AlO(OH). These stones have a hardness of 6.5-7 on the Mohs scale.
