A big beautiful piece of Moss Agate simply set in silver with a little hint of Labradorite. 
The Moss Agate is a pear shaped stone mainly clear with amazing green markings that resemble moss. I've made a prong setting with an open back to allow the light through and show off the stone.
I've added a smaller round Labradorite set in silver with a blackened surround. This links the Moss Agate to the chain which then closes with a lobster clasp.
 
The pendant section is 6cm by 4cm and the chain has a total length of 50cm.
