Benitoite on Natrolite
Cabinet, 12.4 x 6.0 x 5.0 cm
Dallas Gem Mine, San Benito Co., California, USA
Ex. University of Arizona
The largest crystal here is not huge, at 13mm, but these ARE exceedingly gemmy and bright and there are a lot of them! I am told that this habit of benitoite dates to very old workings at the mine, prior to 1960. I have seen only a handful of these brilliant, gemmy crystals in the past, all in old collections. This is a relatively large, display quality examnple with over a dozen fine and gemmy benitoites. From the collection of Hubert De Monmonier (1919-2007), donated by bequest to the University of Arizona Museum to add to their displays and to provide specimens for sale to establish an endowment fund for museum operations, in perpetuity.
