This 25mm black opal donut is one of only two in existence. It is perfectly polished and weighs just over 3 grams. The opal is 25mm across and the band is 5.9mm thick. The opal was cut from the very finest material and the intensity of the fire stands on its own. Gilson Created Opal Black 25mm donut shaped opals
