Section with dendritic sutures — A jewel born from the heart of the Earth and the memory of the sea. This refined 925 silver pendant houses a fossil specimen of Cleoniceras from Madagascar, characterized by an extraordinary iridescent surface that shows opalescent reflections in shades of red, orange, and coppery gold. It is a natural fossilization phenomenon known as ammolite, in which the aragonitic structure of the ammonite shell, over millions of years, has transformed into an opalescent mineral capable of refracting light into unique chromatic play. Each specimen is one-of-a-kind, with a color pattern that shifts depending on the angle and light intensity, recalling the depth of fire and the fluidity of water. The polished silver frames the fossil spiral with sober, contemporary lines, allowing the natural beauty of the gem to remain the absolute protagonist. This pendant brings together geology, time, and goldsmithing in a single object, transforming an ancient form of marine life into a symbol of transformation and eternal light. Each ammonite tells the story of a lost ocean and the slow miracle of stone becoming gem.
