This exquisite 100% natural Ethiopian opal solitaire 0.23 karat is indescribable. Its brilliant cut allows it to radiate with a display of dynamic colors - from reds, blues, greens, to yellows. The simple four prong setting perfectly showcases the opal's beauty, as it requires no extra adornment. *Please note: As all opals are 100% natural, each one is unique and will not be identical to the one pictured. However, all opals possess stunning flashes of color as shown.
