A 100-million-year-old spiral at your fingertips.
This is a one-of-a-kind ring made from a cross-section of an ammonite fossil 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 signet-style form is given a subtle shine with a matte finish in SV925.
I hope you will observe the lines, layers, and crystalline glimmers etched on the surface as a single landscape.
