Ametrine .925 Silver pendant

Ametrine .925 Silver pendant (shop SKU ACPSP37) is a pendant on the shelves at Namaste Bookshop in Manhattan.

Ametrine is a natural bicolor quartz that combines purple amethyst and golden citrine zones in one crystal; Bolivia is the best-known source. In crystal traditions, ametrine is associated with balance. 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. Store jewelry dry and away from lotions, perfume, and harsh cleaners to keep it looking its best.
