No.0020 Ammonite Ring #13

- Specimen Collection -

No.0020

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 are beautifully preserved, and the layers of mineralization create a rich, deep expression.

The band is designed with a sleeker form than a signet ring. The subtle luster of the matte-finished SV925 gently enhances the ammonite's character.

We invite you to observe the lines, layers, and crystalline glimmers etched on the surface as a single landscape.
