Willow Creek jasper is a beautiful well-known jasper from Ada county Idaho. Considered a high-grade jasper, it is porcelain in nature and takes an excellent polish. It often exhibits lovely pastel colors in orbicular and ribbon patterns. Willow Creek jasper is a total classic! It’s so special that it has even earned the title as one of the five fine jaspers of the world (with the others being Morrisonite, Bruneau, Blue Mountain, and Royal Imperial).
