Welcome to Cascade Lapidary

At Cascade Lapidary (CASLAP), we’re all about the rugged beauty and hidden treasures of the Cascade Mountains. We specialize in thundereggs—Oregon’s state rock and a true geological marvel—along with other unique specimens from the Pacific Northwest. Whether you’re a seasoned rockhound, weekend collector, or lapidary artist, you’ll find something here that speaks to your passion.

We offer a growing selection of raw and cut thundereggs, rough rock, and soon, a lineup of quality lapidary equipment built for the work you love to do. We also dive deep into thunderegg lore, identification tips, and the best hunting spots (if you’re up for the adventure).

This is a site built by collectors, for collectors—with a deep respect for the land and the rocks it hides.
