Nice 1950s-60s cocktail ring! A two-carat opal is surrounded by lovely diamonds all set simply in white gold. The opal has shades of blue and green with a bit of orange fire in the right light. The natural opal shows some crazing under 10X magnification, not an issue, and helps identify the stone as natural. Size 7.5. Tests 14k - the mark was removed during re-sizing. The top of the ring measures 3/4" long x 1/2" wide.
