A beautiful Cold Mountain Thunderegg from the Sierra Mountains between Aguascalientes and Zacatecas, Mexico. This remarkable specimen features intricate natural patterns in warm golden, cream, and earthy tones, beautifully contrasted by pockets of translucent blue-gray chalcedony.
Cold Mountain Thundereggs formed within volcanic rhyolite as silica-rich fluids gradually filled natural cavities and fractures, creating beautiful deposits of chalcedony, agate, and occasionally quartz crystals over millions of years.
Cut and polished to reveal its extraordinary interior, this matching pair showcases the unique geological beauty hidden within these volcanic formations.
Height: Approx. 4"
Width: Approx. 2"
Material: Rhyolite with Chalcedony and Agate
