This is a special piece of Koroit Boulder Opal that can be cut into one of the nicest gemstones in your collection. Not for the beginner, this boulder opal is a unique, fragile, and raw multicolor stone, weighing 43.4ct. It has only a light polish to reveal the rare and natural beauty of the color-filled veins. This piece is a beautiful museum specimen that has a rare play of color with only a shallow crack or two (which is common and should rub off fairly easily) perfect to craft into an exquisite piece of fine jewelry or as-is to add to your gem collection. I cannot offer a return or refund on this great piece. Please see photos and video for details and condition. Video may show opals wet under artificial light to reveal subtle colors and patterns on the opals.  Add $4.99 shipping via USPS Ground Advantage.
