Hopeite

Hopeite is a hydrated zinc phosphate with formula: Zn₃(PO₄)₂·4H₂O. It is a rare mineral used mainly as a collectors specimen.

Hopeite crystallizes in the orthorhombic system with prismatic, vitreous white to yellow crystals. It also forms druzy encrustations and reniform (kidney-shaped) masses.

It was first described in 1822 from Moresnet, Liège Province, Belgium and is named after Scottish chemist, Thomas Charles Hope (1766-1844) of Edinburgh University.

It has been found in Zambia associated with lazulite.
