UV Reactive Calcite With Rare NATURAL "Aura" On Pink Amethyst Specimen

A beautiful specimen of very rare natural "aura" UV reactive calcite on pink amethyst from Argentina.

It is very rare to see "aura" coatings on crystals naturally. This particular piece has an iridescent sheen on just the calcite crystals which is caused by an extremely thin deposit of iron oxide.

The calcite is UV reactive and glows a beautiful pink under long wave UV light, pictured.

This listing is for the exact piece pictured.
