Declared the state gem of California in 1985, benitoite was discovered in 1907. At first, opinions about the material’s identity ranged from volcanic glass to spinel and, due particularly to its color, sapphire. However, the stone’s greater dispersion and birefringence values distinguished it from sapphire. Further examination revealed it as a new gemstone.

Benitoite’s sometimes intense blue color usually masks its high dispersion, which can potentially cause stones to twinkle with red and green flashes. Then again, the stone’s scarcity also masks it from the general public, who remain largely unaware of this gem. Nevertheless, when the time comes to cut this rare stone, consumers face a choice between dispersion and body color.

While some admirers will forgo the dispersive display for a darker blue stone, others will want a lighter stone with more evident dispersion. The gem pictured below shows a balance between rich body color and visible dispersion.
