A supremely aesthetic example of this unique material from Koroit. The ironstone matrix provides a sharp visual contrast to the veins of spectral opal - the high polish and color palette in reminiscent of Opal and hardwood. If you spend a little time selecting, you can find these very fine patterns, colorful and entirely unique.
