1.5" Polished Lapis Lazuli Worry Stones

Lapis lazuli is unlike most other gem materials because it is not actually a mineral. Instead, it is a rock composed of multiple minerals. Lapis lazuli's striking blue color is mainly derived from the presence of lazurite. To be called "lapis lazuli," a rock must have a distinctly blue color and contain at least 25% blue lazurite. Pyrite usually occurs in lapis lazuli as tiny, randomly spaced grains colored a contrasting gold.

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.
