Purple Agate Cab Drilled Sterling Silver Pendant

This pendant is listed as Purple Agate Cab Drilled Sterling Silver Pendant (shop SKU SBPUAGP69), and is sold at Namaste Bookshop near Union Square.

Agate is a banded form of chalcedony, a microcrystalline quartz, and takes a polish well. Patterns and colors vary widely from piece to piece. 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 the stone as drilled for hanging. The title describes a cabochon, a smoothly rounded, unfaceted cut. Store jewelry dry and away from lotions, perfume, and harsh cleaners to keep it looking its best.
