A solitaire ring pairs the depth of an emerald with a restrained, minimalist setting that draws all attention to the stone. The faceted cut means that as the hand turns, the green shifts through different saturations - from a deep, bottle-green depth to a bright, transparent flash. The solitaire form does not compete with the stone; all focus stays with the emerald.

Only a small fraction of the reviewed raw material makes it into the finished piece - solely stones with a clean, even colour and good clarity. Good emeralds are becoming increasingly rare and their prices are rising, so this purchase is sensibly priced today. They are set in refined sterling silver 925, with rhodium deposited on the surface to protect the metal against tarnishing and dulling. The alloy is free from nickel and other sensitising additives, making it gentle on sensitive skin. The piece is stamped with the French maker's mark, which attests the origin of the silver.

A solitaire ring with a faceted emerald suits a smart office setting: pair it with a blazer in charcoal or navy and a plain shirt in white or ecru - the green stone brings life to a muted palette without breaking its character. When signing documents or gesturing, the hand catches the eye with that single, precisely chosen stone.
