This modernist pendant is composed of a translucent slice of agate stone in a sterling frame, with three bezel set cabochon translucent stones and crossed with a sterling wire with 2 saltwater seed pearls. There are 2 bails on the back to keep the pendant level. 3" by 1 1/4". The sterling chain is 22 1/2". All acid tested. The scratch on the agate can be felt with a fingernail, but is not visible to the eye. Made by an unknown imaginative artisan. Truly one of a kind.
