14k gold heart pendent reversible w/ blue & red / pink stones 15" 14k chain

14k gold filigree with saphire and rubies presumably. I am not a jeweler and have not had it appraised so I can't in good conscience say anything other than it is mark 14k gold on both the 15" chain and bail of the pendent. I read that only rubies glow under a black light, I don't know about that but I included the pic anyhow. I did find several of these online and tried to price accordingly. The color of the stones is tricky to capture with a camera so I took a lot of pics. Not including the bail it seems to be about 14mm x1 4mm. Let me know if you have questions. I would call the chain either child size or choker. I am happy to negotiate over a bundle and will be adding more jewelry soon:)
