Fluorite from Cave-In-Rock, Illinois, USA

High quality cabinet sized specimens 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.

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.


Our current stock includes:

#1 - 100x100x60MM, 1140 grams

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.

The underneath is a lighter lilac purple and contains a fluorescent mineral, possibly Calcite.

#2 - 170x130x80MM,1205 grams

This is a gorgeous piece measuring 170x130x80MM approximately, and weighing 1205 grams. It is a dark purple, but its true best shows under UV - this specimen has a huge amount of petroleum inclusions under the surface. Under UV light these inclusions glow a gold-yellow colour, making it a fantastic display piece.

Frequently asked questions and delivery information

How do we grade stones?

There is no overall universal grading system for the majority of our products. As such, the grades we use are internal only. They simply refer to higher and lower qualities, but they may be entirely different grades to other websites. C grade pieces are of lower quality than B grade, which is lower than A grade.


How does our ordering and delivery process work?

You place an order via the website. When it’s been picked and packed, your order will be marked as completed and dropped off at our local post office. We have an account with the post office called a “Drop and Go” account, which allows the post office staff to process our parcels when they have free time, rather than me queuing up and delaying everyone else.

I get tracking information etc online when this has been completed. I typically do not send tracking information to customers unless they request it – but if you’ve requested tracked postage, it has been sent tracked! If you have any worries or concerns about your parcel being delayed please feel free to get in touch and I’ll send the tracking info over! We also get delivery confirmations for parcels over 25MM thick by default.


How do international orders work?

After Brexit, with the UK leaving the European Union, certain things have changed with regards to international orders. European Union customers will now likely be liable to pay the same amount of import VAT as any other international customers. You will be responsible for any customs and import fees.


I’d like to return my order for a refund.

No problem at all – just get in touch and we’ll arrange it. You can read our full returns policy here.


What payment methods do you accept?

I can accept Paypal, Stripe, cheque, and direct bank transfers. Paypal and Stripe will both allow you to pay with credit and debit cards.
