This is one of Josh's classic UV designs from his earlier marble days. Josh was one of the first to incorporate truly unique and fascinating UV patterns into his marbles, and this is one of those sweet ones right here, a killer piece of marble history. The pattern reminds me of the radioactive sign, the marble you need for the end of the world, ha. The pinwheeling on the backside is as gorgeous as they come, as usual per Sable gems!
