Benitoite From San Benito County, California

No. 125: Round Brilliant Cut, VS, 0.16 ct., 3.2 x 2.2 mm, faceted by: R. Drummond, $128.00

Benitoite, a barium titanium silicate, is an exceptionally rare gem material. Gem quality crystals have been found in only one location, San Benito County in California. Benitoite is slightly softer than quartz (Mohs' hardness 6-6.5 vs. 7), but it has a higher refractive index and much greater dispersion. The color of benitoite ranges from colorless to a stunning sapphire blue. It shows an intense blue fluorescence under ultraviolet light. Faceted benitoite gemstones larger than one carat in size are rare. Benitoite is sufficiently hard to be set in pendants, pins, or special occasion rings. The above gemstone is small, but would make a nice accent stone in a custom jewelry design. It displays the finest "cornflower" blue color of the best benitoite. There is a small "natural" on the girdle that could be covered in the setting process.
