Fluorite cubes with green‑blue zoning — 158 g

Description

This specimen is a hand‑held group of green‑blue fluorite cubes showing noticeable zoning within the crystals. The piece measures H 10 cm × W 4.5 cm × D 3 cm and weighs 158 g. UV reactive behaviour is present.

The cubes sit together as a compact cluster with clear colour bands visible through several faces; surfaces are intact.

Mineral context

Fluorite is calcium fluoride (CaF2) and commonly forms cubic crystals. Many fluorite specimens fluoresce under ultraviolet light, although UV behaviour varies between specimens.
