Silver Halo Round Faux Diamond Pendent

New Faux Diamond Halo Round Pendent, never worn only bought for the chain it came on (not included). Pendent is absolutely beautiful,it has the big stone in the middle w/smaller stones outlining it, it sparkles like crazy.. Pendents total Length 3/4in., Width~1/2in., Thickness~1/4in., Size of just the Stone~1/8in. There is no stamp on it anywhere that I have seen or found anyway that states what material or silver content is.
