Ammolite is an item found in Red Dead Redemption 2.
Description[]
Ammolite is a green-ish gem, found in a bird's nest located on the eastern cliff-face of a mountain in Ambarino, north-west of O'Creagh's Run. Another gem - Fluorite - is in the same nest, and each may be sold to a fence for $25.00. It does not respawn, thus may only be collected once.
