Aragonite on Calcite on Fluorite
stock #19.1-363
Cave-in-Rock, Hardin County
Illinois, United States
6.3 x 3.9 x 3.3 CM (cabinet)
price: $170


An unusual old specimen from Cave in Rock, southern Illinois. Etched Yellow Fluorite with a hint of purple zoning is the matrix for a treelike spray of slender spikey Calcite crystals that are coated with secondary aragonite. Some of the Calcites have stair-stepped epitaxial growths along the prisms. Ex Larry Conklin with his label, This looks very much like some Minerva #1 mine specimens but Conklins laberl only lists Cave in Rock. A delicate, sculptural piece that is also somewhat fluorescent.
Benstonite on Fluorite
stock #15.1-967-SM-3121
Cave-in-Rock, Hardin County
Illinois, United States
6.7 x 5.7 x 4.6 CM (cabinet)
price: $450
Worldwide mix summer

Benstonite in unusual distinct crystals clustered on Fluorite cubes. Ex Charles Noll collection, a choice example of this uncommon mineral that has always been a very desirable rarity from this region. The Fluorite cubes are also very sharp and clean with strong Fluorescence. These are only available from older collections and most are just a whitish coating on other minerals. This almost certainly came from the Minerva mine but the label does not give that specific detail so we leave this listed as Cave-in Rock only.
Fluorite with Phantoms
stock #17.1-AX- 20-157
Cave-in-Rock, Hardin County
Illinois, United States
8.2 x 6.7 x 4.5 CM (cabinet)
price: $700
pre Tucson 2015 update

Excellent form and sharp edged cubes typify this fine old Cave in Rock Fluorite. In excellent condition and with a nice contrasting matrix of tiny golden Sphalerites and white Calcites. Moderate backlighting makes this glow deep purple hues and the phantoms are very evident. Backside contacting is typical but the 3 dimensional presentation is much better than usual.
SOLD Fluorite
stock #SOLD ALEC-20-160
Cave-in-Rock, Hardin County
Illinois, United States
5.1 x 4.5 x 2.1 CM (small cabinet/ large miniature)
price: $0


A nicely etched "mushroom" like crystal of multi-color Fluorite. An esthetic piece, the core is distinct yellow with a blue overgrowth and a few zones of light purple making for a colorful display. A few tiny Calcites add nice accents. Better in person, this is a nice example with good form, color and in fine condition.
