Top best answers to the question «Where do gemstones come from in oregon»

  • These gemstones are mostly a result of the state's long volcanic history. Oregon's famous sunstone is produced from basalt flows, thundereggs are formed in rhyolite, and the silica that produced much of Oregon's opal, agate, and jasper was dissolved from volcanic rocks by hot groundwater.
