1.5" Polished "Selenite" (Satin Spar) Worry Stones

Worry stones are smooth, polished stones, usually in the shape of an oval, with a thumb-sized indentation. They are often used by people for relaxation or anxiety relief purposes, the same way as some people use a fidget spinner. Typically, worry stones are 1 1/2 to 2 inches across. They may also be referred to as palm stones, thumb stones, fidget stones, etc.

Selenite is a variety of gypsum, a soft sulfate mineral composed of calcium sulfate dihydrate (CaSO4 · H2O). When chemically pure, gypsum is transparent and colorless, but impurities give the gypsum a diverse range of colors and formations. Desert rose selenite and satin spar are just a few of the varieties of gypsum known to have formed though hydrothermal processes.

Note: Satin spar from Morocco is often marketed as selenite, and while it is a variety of gypsum, the name selenite is not accurate in this instance. For the sake of the market, we use both selenite and satin spar to describe these mineral specimens.
