Sagenitic Fluorite Rock Slab 12
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: 4.25" x 3" and is approximately 6.4 mm thick. Weight = 149 grams.
Not polished. Shown wet. Flaws are shown as white lines in the final picture frame.
