Fluorite - etched plate
stock #15.1-582
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
7.2 x 6.5 x 2.4 CM (cabinet)
price: $290


Orange-yellow color Fluorite crystals with a few purple edges from Southern Illinois. The crystals have some amount of etching on some faces while others are smooth and glassy. Minimal rough spots, though not perfect the overall condition and color are choice. One of the more rare colors for an Illinois Fluorite, this piece dates to the 1960's.

Fluorite -classic zoned crystals
stock #20.1-106
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
6.4 x 5.6 x 4.8 CM (cabinet)
price: $1750
Spring 2020

A super blue to yellow-orange zoned Fluorite with excellent form and outstanding surface modifications. A modern American classic, this is a choice display quality specimen that has a main cube presenting a textbook perfect inset in the largest face. Careful examination will find a few very small edge rough points, which are almost inevitable. Overall however this is in very choice condition. The backside is the former point of attachment and is contacted there but the front is well developed. With backlighting this really glows. Hard to find good Illinois Fluorite of this color now except at very high prices. A good value for the quality, in person the color is a shade darker and a bit more blue than purple under most lighting.

Witherite on Fluorite
stock #20.1-083
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
2.8 x 2.6 x 1.8 CM (thumbnail)
price: $140
Spring 2020

A complete ivory colored Witherite crystal sitting on a blue crystalline Fluorite showing classic form. From the famed Minerva #1 Mine, this is a well formed thumbnail specimen in very good condition. The faces of the Witherite have the characteristic tiny stepped structures that are so definitive for this locality.

Witherite - fine US classic
stock #15.1-1060-(CN2017)
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
8.8 x 6.7 x 4.1 CM (cabinet)
price: $750


An excellent old time USA Witherite with great form from the Minerva #1 mine. Classic early 1960s vintage. Ex Dufoe and Noll collections, with fat barrel shape crystals showing well stepped striations on the edges. This specimen also has a good light yellow-orange color and is much more attractive than the more usual plain white. Alston Moor in England and the Minerva mine, (all long closed) produced all of the fine Witherites ever found. Fine pieces like this are now only available from older collections and getting very scarce. This is an especially choice piece, has great wet look luster and displays great from several angles.

Fluorite - zoned, classic yellow-purple
stock #AX-29-058
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
6.1 x 4.9 x 4.1 CM (cabinet)
price: $1150
Pre Holiday 2017

An American classic, sharp Fluorite with excellent color and form from the Minerva #1. Complex cubic stepping and hoppers on several faces and a few Chalcopyrite crystals add a nice accent. The Fluorite cubes are very sharp, in fine condition, colorful and translucent to transparent. Looks great from several angles and with backlighting is really dramatic. The photos here are NOT backlit so it looks as it will in a typical display without special lighting. Sadly such quality Illinois Fluorites are fast becoming rare and expensive. No damage except on the underside where it was attached, this is choice and clean on all display faces.

Calcite on Flourite
stock #AX-20-158
Minerva #1 Mine, Cave-in-Rock, Hardin County
Illinois, United States
6.8 x 5 x 4.3 CM (cabinet)
price: $260


Delicate and esthetic slender crystals of calcite are perched in a jackstraw jumble on purple Fluorite. Despite a few cleaved tips this still displays super well. Classic old time specimen, this sort of material is now quite uncommon.
