No.0012
A 100-million-year-old spiral at your fingertips.
This one-of-a-kind ring features a slice of ammonite excavated in Madagascar, dating back to the Cretaceous period (approximately 100 million years ago).
The internal chambers and suture lines remain beautifully preserved, and the layers of mineralization create a rich, profound texture.
The signet-style form is given a subtle sheen with a matte SV925 finish.
I hope you will observe the lines, layers, and crystalline glints etched on the surface as a single landscape.
