This naturally bright & colorful specimen is a fragment of a full ammolite fossil. Stabilizing and polishing these specimens is typical from this source. This piece has color 3/4 around it and has a beautiful color with a mix of mostly green with yellow, orange, red, and a little blue. It's a beautiful piece, which is a fragment from the outer perimeter of a full fossil! I acquired this piece in September of 2022 during my trip to the ammolite mines in Canada. An outstanding specimen from the locality.
These fossil ammolites are around 70 million years old & these particular ammonites are among the few sources that produces such spectacular brightly colored specimens and gem quality pieces
