The Stones

Gemstones.

Every stone has a story. Every stone has a provenance. We do not simply set gems — we understand them, source them, and honour the millions of years of earth that created them.

Four precious gemstones on black marble

Colombia, Zambia, Brazil

Emerald.

The emerald is the heart of our collection. Sourced primarily from the Muzo and Chivor mines of Colombia, each stone is evaluated for its depth of green, its clarity, and the presence of natural inclusions — the jardin — that authenticate its origin.

  • The most valuable gemstone by carat
  • Natural inclusions (jardin) prove authenticity
  • Mined for over 4,000 years
  • The rarest of the four precious stones

Myanmar, Mozambique, Madagascar

Ruby.

Burmese rubies from the Mogok Valley are the most sought-after in the world. We source stones of extraordinary saturation — the 'pigeon's blood' red — and set them in platinum and white gold to let their colour speak.

  • More valuable per carat than diamonds
  • The Burmese 'pigeon's blood' is the rarest
  • Symbol of passion and power since ancient times
  • Harder than all gemstones except diamond

Kashmir, Ceylon, Madagascar

Sapphire.

Sapphires are the most versatile of the precious stones. From the velvety blue of a Kashmir stone to the cornflower blue of Ceylon, each variety tells a different story. We source investment-grade sapphires with full provenance documentation.

  • Kashmir sapphires are the rarest and most prized
  • Available in every colour except red
  • Second hardest natural substance on Earth
  • Historically worn by royalty and clergy

Botswana, Canada, Russia, Australia

Diamond.

Diamonds are the ultimate expression of precision. Every facet, every angle, every proportion is calculated to maximize light return. We source only investment-grade stones with GIA or AGS certification, and set them in bespoke designs that honour the stone's character.

  • The hardest known natural substance
  • Formed over 1 billion years ago
  • Graded on the 4Cs: Cut, Colour, Clarity, Carat
  • The most universally recognized gemstone
