Origin: Formed within English, by derivation; modelled on an Italian lexical item. Etymons: fluor n.¹, -ite suffix¹.

Etymology: < fluor n.¹ + -ite suffix¹, after Italian fluorite ( C. A. Napione Elementi di mineralogia (1797) I. ii. 373). Compare French fluorite (1808 or earlier; < Italian).

Mineralogy.

A mineral consisting of calcium fluoride, typically occurring as cubic or octahedral crystals, colourless when pure but often coloured by impurities (cf. Blue John n. 2). Cf. fluorspar n.Chemical formula: CaF₂. Crystal system: cubic.
