Green fluorite crystal cluster, sunlight reactive

These green fluorite clusters come from the Hidden Forest Pocket at the Diana Maria Mine in County Durham, England — a well-regarded source known for producing high quality fluorite specimens. The rich green color and natural cubic crystal structure make each piece a standout on its own, but the real story happens under UV light.

Expose these to UV or direct sunlight and they shift to a vivid blue — a natural optical property called fluorescence (fluorite is actually the mineral that gave fluorescence its name). Check the photos and video to see it in action.

A few things to know before you buy:
> Sunlight and UV reactive — stunning color shift from green to blue under UV or sunlight
> Natural cubic crystal structures with rich green coloring
> What you see is what you get — your selection corresponds exactly to the pictured piece
> Size reference shown in photos with a ruler and in-hand shots
> Sourced directly from the Diana Maria Mine, Durham, England

A great fit for fluorite collectors, UV mineral enthusiasts, or anyone looking for a specimen with a little extra wow factor.
