Description

A fine example of octahedral fluorite from Hunan province in China (year 2010).

Fluorite is chemically made up of calcium fluoride (CaF2). It crystallises in the cubic system, which means that its constituent elements are arranged symmetrically around the centres of the cubes. However, under certain conditions, this symmetry can evolve to form octahedral crystals, i.e. a crystal formed of eight triangular surfaces, resembling two pyramids glued together at their bases. 

Hardness: 4 on the Mohs scale (scratches easily)

Cleaning: mild soap and soft toothbrush, rinse well.

Stone dimensions: L: 87mm x W: 65mm x H: 65mm x weight with base: 595g.

This item is attached to the acrylic base with a flexible mastic (easily removable).
