Here we have a fine quality "fishtail"-twinned Sapphire crystal from one of the most classic localities in the world for the Corundum variety. This rather gemmy, very sharp, rather lustrous, striated, "floater", hexagonal Sapphire TWINNED crystal is a marvelous example of how fine the quality of these crystals can get. The colors range from a rich navy blue to a soft sky blue with stark “bands” of colorless and pale yellow throughout. The crystal is essentially pristine on all sides save the very bottom where a tiny contact can be seen, and is absolutely water-clear in about 55% of the specimen. For the quality, this would make a great addition to any thumbnail suite, or a small gem crystal collection.
