Oh, good - I wasn't certain that jewelry stores purchased jewelry, going to a pawn shop was hopefully my last resort. Thanks Maleficent!
It is a variety of different items, a necklace, several bracelets (Diamond, Emerald, Topaz) several different rings (Ruby, Tanzanite, Diamond) and a loose diamond stone that I didn't take into account in my calculations simply because it seems too good to be true. If it is, in fact, what I think it is, it is a 4.5 carot round cut diamond with near flawless coloring. I don't have a loupe so I can't say how the impurities are, but I would guess that it is at worse SI1... Then again, I'm not a jeweler...
