A 100-million-year-old spiral at your fingertips.
A one-of-a-kind ring featuring a cross-section of an ammonite excavated in Madagascar from the Cretaceous period (approximately 100 million years ago).
The internal chambers and suture lines are beautifully preserved, and the layers of mineralization create a profound texture.
The signet-style form is given a subtle shine with an SV925 matte finish.
I hope you will observe the lines, layers, and crystalline gleam carved into the surface as a single landscape.
