Large Cabinet, 22.2 x 19.6 x 11.5 cm
Hill-Ledford Mine, Ozark-Mahoning, Cave-in-Rock Dist., Illinois, USA
Ex. Ross Lillie
As with so many of the Lillie collection pieces, this is unique: Two, huge, lustrous and translucent, dark purple fluorite crystals, to 15 cm in length, are nearly covered in a druse of colorless calcite crystals. A few second generation, ivory colored, doubly terminated calcite crystals, to 1.5 cm in length, are perched on the druse. His label notes the unusual formation of parallel growth on the fluorites, stacked upon a dodecahedral core. The formation is highly unusual and very geometric, Although not gemmy, this piece has a form and presence to it, that is highly unusual. Mined circa mid-1960's. RCL 1318.
