This is a large set of bookends from a thunder egg I dug at the Polka Dot Agate Mine. They are fully polished and have a flat cut bottom. The core of this thunder egg is filled with dark brown chalcedony “agate” with common opal and a small hollow center that extends deeply inside one side and a small trademark spear of tan and brown dotted jasper found in some of these thunder eggs.
together they weigh 7.65 pounds and are each approximately 5” tall, 4” wide and 3” deep. Shipping and packaging are included in the price
