No.0006
A 100-million-year-old spiral at your fingertips.
A one-of-a-kind ring made with a slice of ammonite excavated in Madagascar, dating back to the Cretaceous period (approximately 100 million years ago).
The internal septa and suture lines remain beautifully preserved, and the layers of mineralization create a rich texture.
The signet-style form is given a subtle shine with an SV925 matte finish.
The lines and layers etched on the surface, the glimmer of crystals—we hope you observe them as a single landscape.
