These cabochons were cut from Pacific Northwest jasper, agate, and chalcedony I’ve slabbed and worked in the studio. The region’s stones form through volcanic activity and silica-rich groundwater, which is why you see natural banding, mossy textures, and warm iron-rich tones across the set.

Each piece has been shaped, domed, and polished by hand. They cut cleanly, take a reliable finish, and sit well in standard bezels. I originally prepared these for upcoming ring and pendant builds, but I’m releasing a portion of my studio-cut stones for makers who want ready-to-set cabs without doing their own rough work. If you’re looking to have jewelry made and want to choose a stone before design, you’re welcome to select from this set as well.

Sizes range from small accents to quarter-sized builders, each with natural patterns and consistent dome height. You’ll receive the exact stones shown; some may have slight inclusions, but that’s all part of the fun with natural PNW material.

Material: PNW jasper, agate, chalcedony
