An imposing specimen of totally gemmy, bi-colored, light sea-green and colorless, cuboctahedral fluorite crystals. Crystals reach 4.5 cm. Some crystals have distinct, stepped-growth faces and the piece is nicely accented by a bit of sphalerite. Many of the cuboct crystal faces are lightly frosted, but some are water-clear, giving a neat television-like view in to the crystal interior. From the recent find at Naica.
