Sagenitic fluorite is the mineral form of calcium fluoride. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon. It is relatively soft, 4 on the Mohs scale, but will take a fair polish. The purple sagenite strands or needles create remarkable patterns for eye-catching cabochons.

Dimensions: 6" x 3.5" and is approximately 5.6 mm thick.  Weight = 156 grams.

Not polished. Shown wet.  Flaws are shown as white lines in the final picture frame.
