CREEDITE, Monakoff Mine Cloncurry Cloncurry Shire Queensland Australia (LARGE CABINET)

Creedite is a rare mineral composed of calcium, aluminum, sulfate, and fluorine, represented by the formula Ca3Al2SO4(F,OH)10·2(H2O). This mineral typically forms prismatic crystals that can be colorless, white, or purple, orange, often appearing as delicate, acicular sprays of fine prisms. Its translucency to transparency is characterized by refractive indices of nα = 1.461, nβ = 1.478, and nγ = 1.485. With a Mohs hardness ranging from 3.5 to 4 and a specific gravity of 2.7, it is relatively soft and lightweight.
