Simple but stunning these are AA grade, 13 x 8mm, Phosphosiderite teardrops dangling from sterling silver ear wire. The silver ear wires have just a hint of rhodium added to them. The addition of rhodium slows the tarnishing process, less polishing for you. Phosphosiderite is very hard to come by and these are limited, so don't delay. Phosphosiderite is known as the stone of healing and hope. Who can't use a little bit of that in their lives.
