Cripple Creek Jasper Shere, 3.6 inches in diameter.
From eastern Oregon in the Owyhee mountians. Such a combination of swirling browns and dusty blues, I choose this material for the blue. It has been a challenge to work. It sat on my shelf of shame for months. Perfect for when the core drill is down.
