Specimens from the Gregory Crenko Illinois Fluorite Collection
Greg's interest in minerals started at about age 10 when he found Quartz crystals in local corn fields. Greg has been active in mineral collecting and trading for the past 30 years. At one time he was an avid field collector and found the first confirmed finding of Caffersite (Smithsonian did the analysis) in the Sawtooth Mountains batholith of Idaho.
With good foresight he decided, early on, to specialize in Southern Illinois Fluorites when they were more available. He realized there was good opportunity as a dealer of collectible mineral specimens due to the development of the internet and increasing competition for high quality world wide minerals. He is the owner of Top Shelf Minerals.
Greg is an accomplished self taught guitar player and songwriter and has toured with some national acts. As seen in the photo, he is also an animal lover.
I am pleased to offer this first installment of fine Illinois Fluorite specimens from his collection, which I recently acquired. There will be further installments over the coming months.

We were at the Martin Zinn Mineral Show in Massachusetts in August and sold a lot of mineral specimens. We think we marked the items we sold that were on this site, but its possible we missed one or two.
If an order is placed for a specimen that we
failed to mark as sold - we will certainly apologize and offer a $50 credit toward a different purchase.
With the re-opening of our site - we are having a Keystone Sale (50% off list price) for many of
our specimens. All Mixed Mineral Gallery pages have some Keystone specimens identified with a
The Keystone Sale will last until end of October 2016. This is also a chance to buy a Xmas
