Description
Collectors say that minerals are the universe’s autobiography, written in atoms. Cut and polished, an ammonite’s internal chambers reveal the logarithmic spiral that mathematicians called the ‘golden ratio’ centuries before they understood its name. The iridescent nacreous layer — preserved aragonite from the original shell — creates colors that shift with viewing angle. These Cretaceous cephalopods died 66 million years ago; their shells are more beautiful than they could have imagined.
This specimen originates from Mahajanga Province, Madagascar, one of the world’s most significant localities for this type of material. Collectors and scientists have drawn from this region for generations, and for good reason: the combination of geological conditions here produces specimens of exceptional quality and clarity.
Every specimen is unique. Photographs approximate the visual experience, but the real thing — its weight, its luster under a raking light, the way it catches the corner of your eye — can only be experienced directly.
