Dwarves' Earth Treasures Museum: How to ID Agate Roughs
Baker Egg Thundereggs

 

-Typical colors: Red, white, black, gray, orange, pink. (Other colors are rare)
-Typical sizes: Best agates usually come in small sizes (2 to 12 centimeters long)
-Typical shapes: Rounded to oval, sometimes torpedeo-shaped.
-Most distinguishing characteristic: Flow bandings on white bubbly surface of eggs with some small "brown balls" on it, and all Baker thundereggs have greenish-gray primary band (1st layer).
-Special Notes: Chromatography is common in the Baker Eggs especially those with black, red, and white color combinations. Waterlines are almost always limited to the stalactitic quartz crystal eggs which are somewhat unique to the Baker Eggs.
