About This Piece
A conceptual exploration of form and motion, the Spiritus Ring coils effortlessly around the finger in an organic, spiraling embrace.
The surface is articulated with finely etched linear striations, lending the band a tactile, architectural texture that catches ambient light from every angle. Featuring a fluid open-ended silhouette, this piece balances structural presence with wearable ease, making a subtle yet striking statement whether worn alone or stacked.
