The stone belongs to him.

Men's engagement rings and architectural fine jewellery, built around a single natural stone, chosen by a certified gemologist before the design exists. Nice and Monaco.

A men's fine jewellery maison on the French Riviera.

Stone First

Every GEA creation begins with a stone. Not with a design. Not with a collection.
Each diamond and gemstone is selected and examined personally, for its color, its structure and the presence it carries. Only then does the jewel take form — in 18K gold, with lines drawn to let the stone speak.

Gems Explorers Atelier is a men's fine jewellery maison on the French Riviera. Founded in Nice by Cyrille Deloubrière, Certified Expert Gemologist (EIG Monaco), GEA creates architectural rings around rare natural stones — colorless diamonds, Fancy Color Diamonds and exceptional gemstones.

Bespoke, from the stone up

Each bespoke project begins with a stone — chosen together from GEA's current selection, or sourced on request. Every diamond comes with a GIA or IGI laboratory report. Allow about six weeks from design approval to delivery.

Private viewings in Nice, Monaco and across the French Riviera, by appointment only.

ECHØ

Men's engagement rings. A stone held in tension. ECHØ | Pure reveals a natural colourless diamond; ECHØ | Chromatic explores Fancy Color Diamonds and rare gemstones: Dune, Ember, Sienna, Presence, Abyss. Each one a different temperature of tension.

ØRIGEN

Men's diamond pinky rings. A contemporary reading of the men's signet ring: a natural diamond or a rare gemstone, set close to the hand and made to be worn every day. A personal mark, seen only when it chooses to appear.
