Benitoite is one of the rarest Gemstones on earth

Gem quality Benitoite was found in one place on earth,

a small area in the San Benito county California. The mine

ceased operations in 2006 but remains open to hobbyists

& tourists who pay a daily fee to screen material from the 


What Gem Quality material the mine in San Benito produced

was beautiful had an RI of 1.757 - 1.804 and greater dispersion

than that of the Diamond.The San Benito mine in California

scarce but here - we have some and slightly over a quarter

of a carat and Certified also.
