Pink Titanite (Sphene) crystals associated with black Andradite var. Melanite. This is one of only a handful of specimens found decades ago from a now lost locality. This region has produced a number of fine and rare minerals such as Benitoite, Andradite, Perovskite, Karpatite, Artinite, Fresnoite, Joaquinite and the list goes on and on. Though people have searched, the Titanite locality has never again been found. The pink translucent crystals reach 7mm in size. A true rarity for a California or San Benito collector.
