No.0021 Ammonite Necklace

- Specimen Collection -

No.0021

A 100-million-year-old spiral, close to your heart.

This one-of-a-kind necklace features a cross-section of ammonite excavated in Madagascar, dating back to the Cretaceous period (approximately 100 million years ago).

The internal chambers and suture lines are beautifully preserved, and the layers of mineralized rock create a profound depth of character.

We aimed for a flat plate structure with reduced thickness, integrated into the frame. Our goal was to create a subtle presence that doesn't overpower the fossil, but rather blends in quietly.

The lines and layers etched on the surface, the glimmer of crystals—we hope you observe them as a single landscape.
