Signet Ring Aquamarine

Rings
US$ 397.00

Calm in stone. This signet ring carries a generous 1.8 carat aquamarine in an octagon cut, its cool and transparent blue recalling clear water and open sky. A member of the beryl family, the aquamarine pairs a serene, understated color with the clarity and durability that make it easy to wear every day. The flat octagonal face rests on clean, linear edges that taper smoothly into the band, giving the ring a modern, architectural presence with quiet confidence. A classic signet form, reduced to its essentials and designed for him. Crafted in 925 sterling silver with germanium for enhanced tarnish resistance.
