Thunder Egg with Side View of Stalactites

Thunder Egg with Side View of StalactitesOne half of a fully polished thunder egg with interesting patterns in the agate from stalactites that have grown together inside. I dug this from the PolkA Dot mine in Central Oregon. This item is approximately 4 x 4 and weighs 1. 6 lbs. shipping and packaging are included in the price

I found in the near shore split fish layer of fossil lake

I have cut the bottom flat so that it stand up on its own and can even be used to hold items up on a shelf

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

Turkey that has a deep agate pocket that is beautifully bi-colored light and dark blue with a beautiful matrix surrounding it

It is fully polished and is approximately 4-1/2” x 3” and is a thin cap cut

This piece has been shaped and fully polished and has a botryoidal chalcedony core and the picture rhyolite shell these thunder eggs are known for

Cockerellites liops is very similar in appearance to the rarer species Priscacara

This is a specimen end cut piece fully polished on the face and weighs 8 oz

This large standup natural copper ore piece is from the upper Michigan area with basalt

This is one for the collection

This is very limited material

There is still some debate among researchers about whether this new genus is valid
