Vintage Diamond Ring Size 7 Half Infinity Starburst Design Maker MP Sterling Silver 925. Great for stacking. Could use as a wedding band. Tested as diamonds, but I also demonstrate the ring under UV light next to my designer wedding band set and a moissanite pair of earrings. See last photo. The brighter blue color occurs when it picks up on an imperfection in a diamond. It glows blue with one of the band’s diamonds on the end. It’s less subtle in person, but the best I could get on camera. The moissanite in the earrings glows bright green.
