Derived from the Greek word krystallos meaning ice, rock crystal has been a jewelry mainstay for centuries. 

This transparent, colorless quartz has been used to imitate diamonds, carved for intaglios and even captivated onlookers by putting on a mini light show of its own. 

Rock crystal lockets were particularly popular in the Victorian and Edwardian era -- especially the highly sought after "pools of light" style like this one. 

Pools of light jewelry utilizes simple, undrilled rock crystal either in an orb shape or two halved domes put together to form an orb. When light passes through the orb, it produced a tiny white pool of light, which looks particularly magical when worn as a necklace. 

This exquisite locket features two bezel set halved domes of rock crystal fashioned in rolled gold (also known as gold filled). It hinges at the bottom allowing you to open it and insert a photograph, hair, flowers, or whatever flat talisman your heart desires. 

Locket comes on a new gold-filled chain.
