Halpin's Rocks carries good to high-quality jasper and jasp-agate from the Stony Creek area of California's Sacramento Valley. The colors of our jasper range from red, brown yellow and beige to mauves and greens. The patterns range from marbled, mottled and brecciated to poppy.

We carry rough jasper and jasp-agate by the pound or the ton. This comes in river run and mine run material. We also carry finished material in the form of cabochons, fetishes, carvings and jewelry.
