Titanium Aura Quartz Point Cap Set Sterling Silver Pendant

Among the books, decks, and stones on 14th Street is this pendant: Titanium Aura Quartz Point Cap Set Sterling Silver Pendant (shop SKU SBTAQP89A).

Aura, or aura-coated, quartz is natural quartz with a thin metal-vapor coating that creates an iridescent surface. The coating is decorative; any meaning people give it belongs to personal practice. 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. The title describes a cap setting that holds the piece at one end. Store jewelry dry and away from lotions, perfume, and harsh cleaners to keep it looking its best.
