Actually a unique blend of volcanic matter, anhydrite, and sulfur, these tumbled beauties look like they were plucked straight from a psychedelic beehive. With their wild bands of high-contrast yellow, deep black, and smoky grey, no two stones are ever the same—just like the plants in our greenhouse!

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.
