This is a half of a multi chamber thunder egg I dug at the Polka Dot mine in Central Oregon. Once I cut it to reveal as many chambers as possible I rounded the sides prior to polishing to show off the agate and opal chamber better. It is a great statement piece for your home or yard. It weighs 27 lbs and is 14” x 10” and is fully polished.
shipping on this piece will be charged after purchase due to the varying costs by location due to its size.
