This estate-fresh lady's ring, size 5 (actually between 5 and 5 ¼) is made of 18K (marked-see photo) yellow gold and has at its center a particularly fiery oval opal measuring 7.85mm X 6.55mm and 2.85mm thick which is surrounded by 14 round brilliant cut diamonds. The diamonds measure 1.67mm in diameter, totally .42 carats. The mounting for the ring is a classic tapered shank and the crown of the mounting has been designed so that each diamond is held by a total of 5 prongs. Condition is very good, estate with the following caveat. The opal's very central top surface has a somewhat matte finish due to time and wear, but because of the gorgeous colors within the stone it really doesn't affect the look of it. It is one of the fieriest opals we've handled in a long time with lots of flashes of red-orange, blue and green. This ring is ready to wear with your loveliest outfit!
