The Frieda Bed, situated in Wasco County, Oregon, is a thunderegg site known for producing nodules with vibrant, often fiery agate interiors. These thundereggs typically display rich hues of red, orange, and gold, sometimes accented with mossy or sagenitic inclusions that add intricate detail and visual depth. The rhyolite matrix is generally light to reddish in color, and the eggs are solid and medium to large in size, making them ideal for cutting and display. Frieda Bed material is prized by collectors and lapidary artists for its bold coloration, reliable structure, and strong aesthetic appeal.
