VIRGIN VALLEY OPAL from northern Nevada USA is considered to be the brightest, most colorful opal on the planet.
Most Virgin Valley Opal is for specimen purposes only and these are the most beautiful specimens found anywhere. This is because the vast majority of the opal found in Virgin Valley has stability problems and crazes/cracks soon after removal from the ground. Rarely opal from the valley can cut proven stable gems but when they do they are among the highest priced opals in the world and are far more rare and valuable as collectors gems than opal from major fields producing vast amounts of stable stones.
The opal in Virgin Valley is found in-place within a defined zone of hard clay of bentonite/montmorillionite. Most pieces are solid precious opal CASTS (without any petrified wood) that replaced the wood twhich rotted away and the silica solution that formed the opal percolated into the empty cavities and formed the opal. Some precious opal is also found associated with petrified wood but precious wood opal (like conk) is extremely rare and valuable.
