I actually don't know what the heck this is. Hoping someone comes by and tells me - I think it's an agate - I've had it for 30 years - it's got little round nodules in one part - a branchy design like a coral tree. Anyway it weighs 5 ounces - it's 1/4 thick and measures like 3 1/2" x 3 1/2". Only one I have.
Will ship via USPO with delivery tracking.
