4 Grams Size 7 Marked 14k, unknown markings I hunt for treasure & pass it on. Most of the jewelry I sell is used/vintage & uncleaned. Patina takes years to develop on a piece cleaning it only takes minutes. If you would like something cleaned let me know. To figure out ring size cut a small strip of paper & wrap it around the finger you want to wear the ring on RIGHT below the knuckle. Then measure the length & find the size: Size 4: 1 13/16 inches Size 5: 1 15/16 inches Size 6: 2 1/16 inches Size 7: 2 1/8 inches Size 8: 2 1/4 inches Size 9: 2 5/16 inches Size 10: 2 7/16 inches Size 11: 2 9/16 inches Size 12: 2 5/8 inches Size 13: 2 3/4 inches Size 14: 2 7/8 inches Aquamarine Amethyst 14K Gold Ring Size 7
