I bought this stone a long time ago. It is a Serpentine stone. I have had it sitting on my bench staring at me. I wasn’t going to buy it because I did not think I could set it in an impressive enough setting for its’ size: the stone is 4.5 inches long, 1 inch wide and 1/2 inch thick. I could not be happier with this piece. It’s larger than my hand. The pieces of handmade chain look like tendrils. I spent about 4 minutes on these pictures so I will have to redo them when I have time. Just wanted to share this necklace before I’m off to class in Door Co for the next few days.
