Unstabilized opal specimens from the Royal Peacock Opal Mine in Denio, Nevada, near Virgin Valley. Preserved in water in sealed clear glass capsules these opals are jaw dropping. Nevada Virgin Valley opals are placed in water to prevent them from cracking, as the ground in the area is extremely moist and the opals are accustomed to a wet environment. When opals are quickly dried out after being removed from the earth, they can crack. Some types of opals, known as hydrophobic opals, absorb water and become temporarily transparent. An ancient lake covered most of the Virgin Valley area, which was filled by a tremendous amount of volcanic ash that blanketed an abundance of natural trees and plants on the valley floor. Over time, heat and pressure formed a silica gel that percolated through the ash and filled various cavities, eventually solidifying into a spectacular variety of opals. The presence of certain minerals and the unique chemical composition of the water contributed to the vibrant colors and patterns of opals found in the region. Royal Peacock Opal Mine produces a unique and prized variety of the gemstone in a kaleidoscope of hues, flashing with blues, greens, oranges, reds, and yellows. This breathtaking effect comes from light interacting with the silica spheres within the opal's structure. The base color, or the color behind the play of color, can vary from milky white to a deep, rich black. The mine is known for its black opals, which feature a deep, dark body with vibrant, iridescent flashes of color. Nevada's state gemstone is the Virgin Valley black fire opal, designated as the official state precious gemstone in 1987. Opal was first found in Virgin Valley around 1905 and word spread bringing a "rush" of miners to the area by 1907. The Roebling opal discovered at the Rainbow Ridge Mine in 1918 is one of the more famous opals from Virgin Valley, now part of the Smithsonian collection. These specimens have never been dry and therefore they remain in perfect, natural, undegraded condition, as originally found. the larger of the two appears mostly clear, indicating it may be one of the rare hydrophobic opals that, when stabilized, may explode into an opalescent rainbow. The true beauty of these pieces may remain a mystery for the winning bidder to be the first to discover!
