Offered for your consideration is a gorgeous example of a 'Pool of Light' locket set in a gold filled mount. It is 5/8" in diameter and weighs 3.4 grams and has a secure closure. The crystal definitely transposes writing as a true rock crystal should.
It would be a great pendant at the end of a watch chain or equally impressive as a charm on your favorite bracelet. It is just waiting for pictures, a lock of hair or dried flowers.
