Collection: Red Flashy Iridescent Ammonite Fossils for Sale

Red flashy iridescent ammonite fossils are among the most visually striking ammonites, valued for their vivid natural flashes of red, orange, and gold. These authentic specimens date to the Late Cretaceous period and originate from fossil-rich marine deposits in Madagascar.

Their brilliant coloration is the result of naturally preserved ammolite, formed when ancient aragonite shell layers were transformed through geological pressure and mineralization over millions of years. When polished, these ammonites reveal dynamic color play that shifts with light and viewing angle, while remaining completely natural and unenhanced.

Red flashy iridescent ammonites are highly sought after for display, advanced fossil collections, and educational exhibits, offering a rare combination of scientific significance and natural artistry. Each specimen is unique, providing a one-of-a-kind glimpse into Earth’s ancient oceans and the evolutionary history of ammonoid cephalopods.
