Here's a new batch of Polka Dot Agate cabochons we just cut. Polka Dot Agate is found not far from Madras in Central Oregon and is a classic North American agate known and loved the world over. It comes in a wide range of colors and patterns but it is not polka dot without the, well, dots. One has to cut a fair amount of this material to yield good cabs as it has a tendency to have nasty fractures and disappearing dots. But we love it, and will likely always have it in our inventory.
