Dwarves' Earth Treasures Museum: Thundereggs from
Spießberg, Thuringia, Germany
.
Coming from one of many thunderegg locations around
Germany, this location produces brownish thundereggs with coarse quartz
grains and greenish "rings" and white to light pink colors. I don't know
much about them.

Rough Appearance: Has greenish pertile
attached to them with some coarse quartz crytals sticking out.
White agate with greenish "rings" is a dead giveaway.
