Hailing from the fjords of Norway, this igneous rock is famous for its "schiller effect"—a fancy way of saying it has those addictive, iridescent flashes of silver and blue hidden within its dark, charcoal-grey surface. It’s like looking at a stormy sea under a full moon.

Note: Images are a representation of the stones you will receive. Each rock is unique, and small variations in color, size, banding, etc. is to be expected.
