Pyrite .925 Silver Ring Size 7

Pyrite .925 Silver Ring Size 7 (shop SKU IGFBPYR69) is a ring on the shelves at Namaste Bookshop in Manhattan.

Pyrite, sometimes called fool's gold, is iron sulfide and often forms sharp cubes or glittering clusters. Peru is a well-known source. In crystal traditions, pyrite is associated with vitality and protection. Those ideas belong to folklore and personal practice, not to any medical claim.

Sterling silver is 92.5% silver, often stamped .925; like all silver, it can tarnish over time and can be brightened with a soft polishing cloth. The ring size is 7, as stated in the title. Store jewelry dry and away from lotions, perfume, and harsh cleaners to keep it looking its best.
