This unique stone is opalized wood from Indonesia.  The colors are stunning watery shades that I set as pendants with bubbles of sterling silver dripping off like water .... Since these are so unique I make them to order with the stone shape and color available at the time.  The last slides show the unset stone options I have available now, please choose your favorite and I'll set similar to the finished pendants shown in first slides.  
Handmade by me in my Santa Fe New Mexico studio.
