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 profound aesthetic.
The signet-style form is complemented by the subtle glow of the matte-finished SV925.
I hope you will observe the lines, layers, and glimmers of crystals etched on the surface as a single landscape.
