A Gorgeous Vintage Australian Opal and Diamond Ring in 14K Gold from the Estate Jewelry Collection. The center of this beautiful gemstone ring holds a genuine Australian Opal gemstone with vibrant blues and greens when turned in the light. The opal measures about 7 x 9mm oval. I have it displayed in the photos two ways one black and white background. The lighting and background in the white backed photos tend to wash out the natural color in the stone. There are four (4) genuine diamond accents on the sides. The setting is solid 14K yellow gold as marked and tested. Overall this ring measures about 3/8 inch long by about 11/16 inch wide and is in lovely estate condition. Ring Size: about 5 (could be resized by your jeweler or ask me about using mine before shipping). International shipping available, please ask.
