Ascend silver ring with natural yellow sapphire

Rings
US$ 153.00

Light made wearable. At the center of the Ascend ring sits a 0.32 carat natural yellow sapphire in an octagon cut, glowing in a warm golden tone that moves between soft champagne and vivid honey. Sourced in Madagascar and completely untreated, it carries the bright, optimistic character of the sapphire family together with the exceptional hardness and brilliance that only corundum achieves. Around it, the stepped band rises in defined tiers, each level catching the light at a different angle so the silhouette stays clean yet quietly architectural. Designed for her and for him, for those who like warmth with a sense of structure. Crafted in 925 sterling silver with germanium for enhanced tarnish resistance.

The atelier's hand

Conceived, cast and finished by a single atelier - so that the hand that drew the piece is the same that sets its stone.
