Ruby #ruby #diamonds #jewelry Size 7..genuine, approximately 1.5-2ct, and earth mined Ruby. This stone is old, it came from high end, gold jewelry. There is a tiny bit of wear from someone loving it dearly. You can’t see it with the naked eye, it looks perfect. It’s a fabulous find, those old ones have some character. Rubies glow under backlight. The "Glow" Factor: Their vibrant crimson hue comes from trace amounts of chromium. Because chromium reacts to ultraviolet (UV) light, natural rubies fluoresce and seem to glow from within when exposed to sunlight. Solid .925 silver
