-Typical colors: Yellow, black,
tan, white: Uncommon colors are gray, lavendar, orange, & purple.
-Typical sizes: Commonly larger than 6 centimeters (?)
-Typical shapes: Concretion-tyoe (rounded, bumpy. fossil-like)
-Most distinguishing characteristic: Holly-shaped agate in concretion matrix. Nodules were originally fossils (crinoid heads, brachipods, etc.) before being expanded by water action, but some nodules retain their original features.
-Special Notes: Some nodules contain black and red bandings, a very rare color combination in any agates. Any kentucky agate rough that are originally large brachipods are very rare.
