Kassite

Kassite is a rare mineral with formula CaTi2O4(OH)2. It crystallizes in the orthorhombic crystal system and forms radiating rosettes and pseudo-hexagonal tabular crystals which are commonly twinned. Crystals are brownish pink to pale yellow and are translucent with an adamantine luster. Cleavage is distinct and the crystals are very brittle. Mohs hardness is 5 and the specific gravity is 3.42. The mineral is biaxial negative with refractive indices of nα = 1.950, nβ = 2.130 and nγ = 2.210.
