Noble opal

Noble opal 13.09 ct


A large cabochon of natural noble opal weighing 13.09 carats. Body-color – white, translucent. There is a beautiful opalescence in several colors (see video). We emphasize the harmonious oval shape of the cabochon, which is valuable for opals. The fact is that the weight loss of raw materials when processing the oval shape is greater than when making free form cabochons, which is widespread for natural opals. Therefore, oval opals, especially of such a large size, are much less common and are valued higher.
