A 100-million-year-old spiral on your fingertip.
A one-of-a-kind ring crafted from a section of a black ammonite excavated in Madagascar during the Cretaceous period (approximately 100 million years ago).
The ammonite fossilized over a long period of time, replaced by iron-containing minerals, resulting in its deep black color.
The internal shell chambers and suture lines remain, revealing subtle variations in light and layering within the black.
The signet-style form, combined with the gentle texture of SV925 matte finish, creates a presence that embodies both weight and tranquility.
We hope you will observe this ancient, blackened, mineralized trace as a unique landscape.
