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.

The Romantic Gem

Ruby

For centuries, rubies have captured hearts, often earning the title of 'romantic king' among gemstones. While known for its iconic red hue, rubies actually boast a diverse palette of reds - each tone radiating its own unique charm. Rubies are prized for their hardness and clarity, telling a story of fiery origins and long-lasting beauty.

The Prosperity Gem

Sapphire

Long associated with royalty, the sapphire evokes an air of timeless elegance and sophistication. While the name "sapphire" often recalls deep blue hues, these gemstones actually occur in a breathtaking variety of colors.

The creative gems

Fine gemstones

Tourmalines, spinels, garnets, and precious spessartites – are the creative gemstones that bring playfulness and expressivity to timepieces. Unlike traditional gems, these stones offer a spectrum of hues expressing a sense of joy and individuality.

Securing beauty

Behind every gemstone set in a timepiece lies a dedication to precision, patience, and unwavering attention to detail. Combining aesthetic refinement with technical performance, the Maison’s creations feature four types of gemstones settings:

Vivid color and lasting allure

Synthetic gemstomes

Synthetic gemstones offer significant advantages in both technical movement and aesthetic aspects of a timepiece. Their vivid saturation enables innovative applications such as the use of Super-LumiNova for enhanced visibility. Beyond their visual appearance, these stones present high durability and longevity, guaranteeing reliable performance over time.

Responsible sourcing: a core value

Ethics and sourcing

Ethical sourcing is at the heart of the Maison’s commitment to responsible craftsmanship. All stones are certified by the Responsible Jewellery Council and comply with the Kimberley Process, ensuring traceability and transparency across the supply chain. The Responsible Jewellery Council is the world’s leading sustainability standard-setting organization for the jewelry and watch industry, ensuring that responsible standards are upheld globally. The Kimberley Process reinforces this commitment by removing the circulation of conflict of diamonds.
