Rare Opalescent Cleoniceras


- Excavated from the depths of the Mahajanga Jungle in Madagascar.

Designed by nature - created by eons.

The lustres of iridescence is a reaction to light reflections within the nacre of the external shell. These Cleoniceras and Desmoceras Ammonites have absorbed minerals from surrounding deposits dating back 120,000,000 to 110,000,000 years. It is also believed these prehistoric cephalopods had an iridescent nacre, much like the internal structure of the modern Nautilus found in our oceans today.


A rare and superior collection unlikely to be repeated.
