- Dallas Gem Mine (Benitoite Mine; Benitoite Gem Mine; Gem Mine), Dallas Gem Mine area, San Benito River headwaters area, New Idria District, Diablo Range, San Benito Co., California
The Dallas Gem Mine in California is known primarily for two things: benitoites and neptunites, both world-class for the species. This is a fine example of neptunite from the collection of Al McGuiness. The crystals, to 1.5 cm, have wonderful sharpness and luster, and are in superb condition. They look beautiful against the stark white natrolite.
