Sterling silver, 22K gold, and a big beautiful piece of Boulder opal from Australia.  This is a really cool piece of boulder opal, to get the full effect, PLEASE LOOK AT THE VIDEO THAT SHOWS ALL THE DETAIL.  The photo of it in my hand gives you the best idea of the stone and was taken in natural light.  The opal with the setting and piece it hangs from measures 2" wide by 2-1/4 long" and is 18" total around the neck.  The chain is adjustable shorter.  If you need more chain, let me know!
