🔍 Stone Description:
This specimen is Virgin Valley Opal from Nevada, USA, one of the world's most famous localities for precious opal. Renowned for its spectacular play-of-color, Virgin Valley opal forms within ancient fossil-bearing volcanic ash deposits and is highly prized by collectors and lapidary artists. Many specimens display vivid flashes of color that shift dramatically as the stone is moved under light.
📌 Highlights:
Color Palette:
Cream, white, honey, and amber body colors with vibrant flashes of red, orange, yellow, green, blue, and violet.
Patterns:
Broad flash, pinfire, rolling flash, harlequin, and mosaic play-of-color. Many specimens occur naturally within rhyolite or volcanic ash matrix.
Hardness:
~5.5–6.5 on the Mohs scale — durable enough for display and lapidary, though care should be taken to avoid impact and dehydration.
Location:
Virgin Valley, Humboldt County, Nevada, USA — home to some of the finest precious opal deposits in North America, including the famous Royal Peacock, Bonanza, and Rainbow Ridge mines.
Formation:
Formed millions of years ago when silica-rich groundwater filled cavities within volcanic ash and replaced ancient wood and other organic material. The orderly arrangement of microscopic silica spheres creates the opal's spectacular play-of-color.
Rarity:
Very High — Virgin Valley is one of the few locations in the world producing precious black, crystal, and fire opals with exceptional play-of-color. Fine-quality material with bright, stable color is highly collectible, and many of the historic deposits have become increasingly difficult to access.
