Description from the seller
This pendant features a section of Cretaceous ammonite fossil, where fossilization processes replaced the original shell with deposits of crystallized pyrite. The metallic surface, alternating with areas of microcrystalline pyrite, tells the slow intervention of geology that transformed a marine organism into a unique mineral fragment. The lower part shows orange calcite with translucent veins, a testament to the mineralizations that filled the ammonite's septal chambers after its extinction. A jewel that combines paleontology and mineralogy: the spiral structure of the ammonite, emblem of natural balance, meets the metallic brilliance of pyrite and the warm tones of calcite. Every detail speaks of a remote time, over 65 million years ago, when these mollusks dominated the Mesozoic seas. Wearing it means carrying with you an authentic fragment of Earth's history, transformed into a piece of contemporary goldsmith art.
