Thank you for viewing. An elegant ring featuring a beautiful black opal and six diamonds. It has a vibrant play-of-color with blue hues and flashes of green. The play-of-color is subtle, but it sparkles and shines when light hits it, making it a fascinating piece to observe under various light sources. The condition of the metal is also good. - Material: Yellow gold, k18, hallmarked - Stone type: Black opal Size: 8.5 (Japanese ring size) Comes with a gemological report. The box in the photos is not included. Also recommended for boulder opal lovers.
