Owy-Thundereggs

Owyhee Thundereggs – Dug by Hand in the Pacific Northwest

Straight from the rugged beauty of the Owyhee Mountains, these remarkable Thundereggs were self-collected by Rebel Rockhounding from a private location generously shared with us. Every piece pulled from that rocky wall came at the cost of hard work, blistered hands, and plenty of pick-and-hammer sweat—true rockhounding spirit at its finest.

These natural treasures range from golf ball to coconut size, each one a mystery until sliced open to reveal its heart of vivid agate banding, delicate waterlines, and mesmerizing color zones. No two Thundereggs are ever alike; each captures a unique moment of volcanic artistry from deep within the Pacific Northwest’s geologic past.

Every cut face tells a story—hand-dug, naturally formed, and proudly collected in the wild Owyhee hills by Rebel Rockhounding.

PRICE: Price is per pound.

DISCLAIMER: These are raw, uncut stones—just waiting to be turned into beautiful cabochons, carvings, or display pieces. The photos show what these rocks can look like once they’ve been cut and or polished, for reference. We personally handpick our rough to bring you the best quality material we can find, and every piece is different once it’s opened up—that’s part of the fun! If you’re not happy with what you get, no worries—you can send it back for a refund as long as the rough hasn’t been cut.
