Fluorite from Cave-In-Rock, Illinois, USA

A high quality cabinet sized specimen of purple cubic Fluorite from the world famous Cave-in-Rock area of Hardin County, Illinois, USA.

This area produces excellent quality specimens of Fluorite you can see in many fine mineral collections.


The piece we have in stock is not quite on the 'world stage' quality wise, but could be at home in a smaller museum or quality mineral collection.

It measures 100x100x60MM approximately and weighs 1140 grams. It is a dark purple, and would ideally be displayed with a backlight or on top of a light to get the most of its colour. I have shown three photos of it lit purely by an LED mobile phone torch for your reference.

While there is some edge damage to some crystals, they are largely in good condition. The intricate cubic growths look almost alien; this seems more like an artefact from science fiction than a natural mineral. The underneath is a lighter lilac purple and contains a fluorescent mineral, possibly Calcite.
