Item Description

A classic Rogerley Fluorite thumbnail featuring a nearly 100% WATER CLEAR, interpenetrant twin with sharp, well-formed faces and that gorgeous green color. The combination of the twinning, the transparency of the crystals and the iconic hue makes these specimens so desirable. Additionally, the specimen shows a bit of the purple daylight fluorescence that is often observed in Rogerley Fluorites. From the worldwide thumbnail / miniature collection of Irv Brown.
