Huge Black Lucky Strike Thunderegg

A very big and dramatic thunderegg full of dark flinty agate and a botryoidal cave. This is interesting also in that it features a tilt. The fine leveling lines are so precise and parallel that they could be used as a ruler - but you can see that the flat floor of the cave (essentially a level itself) is at a different angle. This indicates that the ground the thunderegg was in during formation has shifted.

This weighs about 3 pounds and measures approximately 4 3/4"wide, 5"high and 2"deep.

This thunderegg is for sale. £7.50 Please contact David Rix for buying.
