Fluorite (fl) on Sphalerite
Rosiclare Level, Minerva #1 Mine, Cave-in-Rock, Hardin Co., Illinois, USA
Small Cabinet, 8.2 x 6.7 x 4.7 cm
Ex. Ross Lillie
Noteworthy small cab specimen from Minerva that has the 'big three' characteristics - superb luster, zoning, and gemminess. The glassy Fluorites are clustered into two main groups on top of the Sphalerite matrix, with the largest being 1.7 cm. The color zoning is peerless, with sharp, elegant zones of yellow-amber, purple, and blue. There is a little bit of edge wear, but that does nothing to diminish the quality that denotes these Fluorites. The Fluorites are even fluorescent. Mined in 1981. RCL1978
