1.9" Polished Fire Agate 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.

Agate is a variety of microcrystalline quartz (chalcedony) that displays translucence and, in some cases, banding. Agate primarily forms when silica-rich fluids fill pockets within rocks and/or fossils, depositing the silica along the walls of the rock. This process can result in banding patterns, as the compositions and impurities of these depositing fluids change over time. These banding patterns can either form as flat layers, creating linear patterns known as waterline agate, or as rounded layers, forming more common ring-like patterns. These patterns depend on the surfaces available for deposition.
