That is a created opal, they are man made and are created to mimic fire opals. I have a few because it is my birthstone, but i am too superstitious to own a real opal... Lol beautiful piece!
Why are you harping on her for not answering questions luvubear2 ? Some questions asked ofher are answered in the original discription up above, like the size...and all others are pretty easy if you use your own sight! ITS AN OPAL< havent you seen an opal before? Obviously it is costume, because if it were real silver 10 14 or 18...it would have been mentioned in some manner. --->IT IS QUITE BIDDABLE -- SHE HOPPED THRU ENOUGH HOOPS TO ANSWER YOUR QUESTIONS> I AM NEW HERE MYSELF, AND THAT KIND OF SLAPPING PPLZ AROUND I WONT TOLERATE WITHOUT A GOOD REASON. --Great auction leecarley 5! -- You are doing just fine.
