Pietersite Slab .925 Sterling Silver Ring Size 10

Among the books, decks, and stones on 14th Street is this ring: Pietersite Slab .925 Sterling Silver Ring Size 10 (shop SKU NCPIER24E).

Pietersite is a trade name for a brecciated, chatoyant stone of hawk's-eye and tiger's-eye silica, typically in gold, blue, and brown swirls. In crystal traditions, pietersite is associated with vision and change. 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 10, as stated in the title. The title describes a slab, a flat slice of stone. Store jewelry dry and away from lotions, perfume, and harsh cleaners to keep it looking its best.
