Expressivity in gemstones
Creation begins with the stone itself. The gemstone lies at the heart of every gem-set timepiece, serving as the starting point of its conception. These gemstones are carefully sourced and selected, ultimately resulting in rare timepieces. Gemology is where aesthetics meet precision, and beauty meets value. The Maison incorporates precious stones, fine stones, and synthetic stones to embellish its intricate movements. Whether set on the dial, bezel, or skeleton and carefully chosen for their quality, brilliance and expressivity, gemstones infuse calibres with emotional depth technical mastery.
The Eternal Gem
Diamonds
The Maison crafts expressive timepieces using first class diamonds, meticulously cut in both baguette and brilliant styles. When selecting a diamond, the "4Cs" are essential: Carat, Color Grade, Clarity Grade (VVS+ only) and Cut Grade. While being extremely bright, diamonds are also the hardest natural mineral: only one diamond can cut another diamond.
