Chain sold separately.
Treatments: None.
Origin: Stone cut and polished in the USA. The material was mined in Franklin, New Jersey. The mine closed in 1954. Hardystonite is a calcium zinc silicate, one of the famous Franklin minerals which to this day has never been found in appreciable quantities anywhere else in the world. "Zinc schefferite" is a varietal name for diopside from Franklin, especially the caramel-colored material.
Close inspection suggests some of the tan material is andradite garnet and some is zinc schefferite. The hardystonite is ivory-white in daylight.
Another rare and exotic stone you're unlikely to find in a store.
