Blue Mexican fire opal, cz and blue crystal necklace

I have a matching ring that goes to this necklace if interested the ring is a size 10. Can be purchased separately! This beautiful necklace is stamped 925 and tested for sterling! On a 925 Mexico stamped snake chain that measures 18”. Some minor kinks in the chain but you cannot tell when wearing its not apparent unless your really looking for a flaw! This chain is a thicker snake chain and shiny so it goes with it. I have posted pics. If you would like a different chain I might be able to accommodate. This one came w the chain as it was my aunts.
