gold opal pendant necklace

this was from a brand deal (can't remember where from!) i had and 18k gold plated (i don't think the chain is real gold). in my opinion, the pendant is elegant and way too pretty for this chain, i would probably put it on a real gold chain to match the quality of the pendant. the chain is pretty on it's own, but looks a bit cheap. i've only worn this about 3x. and i do believe it's a 16 inch chain. it's a quality piece. :)
