-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.
