Hand-collected from the legendary Lucky Strike Mine northeast of Prineville in Oregon's Ochoco Mountains, this old-stock material represents one of the most famous and distinctive thunderegg veins in the Pacific Northwest.

The cut slices beautifully display the signature traits that make Lucky Strike specimens a holy grail for collectors. some pieces feature the iconic, prized "winged" or butterfly-shaped central core. The interiors showcase a striking contrast of deep wine-red to purple-plum jasper intergrown with dense, translucent smoky-gray chalcedony and mossy, olive-green plume inclusions

The rough nodules and slice backs exhibit the classic, heavily textured "cauliflower" rhyolite matrix with its distinctive iron-green weathered rind. For scale, a US quarter is included in the rough grouping photo,.
