OFFERED: This beautiful KREMENZ JEWERLY CO. necklace, ring and earring set features a heart-shaped pendant adorned with a ruby in the center and a lobster clasp. A pair of pierced heart shaped earrings, each also adorned with rubies in the center. The delicate 14kt gold filled or plated ( that's what they're known for) chain is 18 inches in length; Size 7 ring with a ruby in the middle of the heart. This is an excellent find that you can make the perfect gift. My brother gave this set to me back in the 1970s, he told me they were real rubies, I checked and they do glow under a black light. Lab rubies also glow so I'm really not positive.
