This stone is so amazing with it's blacks and grays looking like a dark forest.  It is set in sterling silver which enhances the stone's colors and it's teardrop shape is lovely and rather unusual.  On the backside is a snowflake since to me the stone looked like a winter scene.  It's going to be hard to part with.
It measures 1.50" tall and 1" wide.  The sterling chain is 18".
