Gorgeous top quality petrified opalized wood stones are set in sterling silver bezels and hang on round sterling ear wires. I've used an asymmetrical design with one earring being smooth and one earring having a beaded pattern on one side. The backs are open showing the quality of the beautiful opalized petrified wood. This will also lighten the earrings as well. These are hanging on round ear wires which help the earrings from being pushed out by a sweater or scarf.
