Smoky Quartz .925 Silver Earrings

Among the books, decks, and stones on 14th Street is this pair of earrings: Smoky Quartz .925 Silver Earrings (shop SKU IGSMQE45).

Smoky quartz is the brown to gray variety of quartz, colored by natural irradiation. In crystal traditions, smoky quartz is associated with grounding 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. Because the material is natural, its color and pattern vary from piece to piece. Store jewelry dry and away from lotions, perfume, and harsh cleaners to keep it looking its best.
