Shiver me timbers: this one starts with cold in its heart, yeah, crystalized quartz—the ice, and the agate’s center. But then the agate warms up considerably. Surrounding it are waves of favorite colors: four variations of blue and three of purple, all of them laid out in those classic, powdery, old-school colors. Call it an agate with both great color change and iconic colors. This well-polished agate measures approximately 4 1/4” x 3 3/8” x 1 1/8” and weighs 14.1 ounces. Free US shipping only.
