NWOT Brand new fire opal gemstones set in hearts pendant on 19" 925 chain

marked and tested 925 this is a gorgeous new without tag orange fire opal gemstones set in 925 heart shapes with topaz accent circle pendant signed STS. please note I had this down as citrine but the person I bought ut from had another abd they said it was opal. they have a presidium tester. now presidiums aren't always right so maybe it is indeed opal but I'm going with what I was told with this disclaimer.
