Opal Sonar Necklace // Handmade and One of a Kind Rectangular Australian Boulder Opal Necklace on Cable Chain

This necklace is made for someone that has something to say! The bottom left of the stone is echoing out across the landscape-like Boulder Opal, like a ripple in a pond or a voice in the dark.

I made this pendant on an 18'' chain that will hang just below most collar bones, but if you would like a 16'' 20'' 24'' or 30'' chain, just let me know in the notes at checkout!

Care Instructions

To clean your Mettle by Abby pieces, simply use a soft toothbrush in warm, mild soapy water. This will help remove dirt and oil from the gemstones and make them shine again, as well as keep the silver and gold looking bright and clean.

To polish silver Mettle by Abby pieces, simply buff with a silver polishing cloth. If you really want to give it a shining, you can use a silver polishing cream and then rinse it with water when done.
