i've used a beautiful morado opal in this piece. also called purple opal, it doesn't have the opalescent qualities we're accustomed to, but it does have its own magic. i've matched it with a moon face and a forget me not that has just a bit of gold leaf in the center. the silver is 960 silver, the piece is heavy and large and hung on a sterling chain. also some added patina. height of pendant: 3 and 5/16" width: 1 and 11/16" length of chain: 20"
