PoliceAuctions.com  -  false advertising

I won auction which states it's was a 1.53 c.f. emerald ring. The picture clearly shows emerald stones. And then when my item just come in the mail it's not emerald stones at all like it says it is or like the picture shows .it jade stones nothing like emerald. So what is that how use work is it false advertising, I'm going to take this futher for false advertising. I'veTakin this to my lawyer.
