Beautiful fine quality 4.10 carat Australian lightning ridge dark crystal opal Opal cabochon. Translucent dark gray body-color with large vivid green flashes play of color. There are also some blue and lavender colors. The Opal is all natural untreated. It is a solid opal, not a doublet or triplet. It measures approximately 15.6 x 10.1 mm. This opal is from a large lifetime single-owner collection. Opals display their colors differently according to viewing conditions and direction, so I have included photos to show some of these differences. The pictures on the rock backgrounds, and the video give the most naturalistic impression. If you are not completely satisfied when you experience it in person, you may return it for a 100% full refund as stated below. SKU 4269i.
