Semi-Precious Stone Mosaics

Hardstones delicately cut and assembled into luxurious mosaics, where geology becomes ornament and material becomes jewellery for architecture.

Each tessera is selected for colour, clarity and character before being precision cut and hand assembled into intricate compositions. The result is not simply decorative - it is materially expressive, rich in depth, lustre and natural variation.

Combinations may include Lapis, Malachite, Jasper, Rock Crystal, Amethyst, Tiger Eye, Petrified Wood, Carnelian, Mookite, Agates, Onyxes, Mother of Pearl and Porphyry, among others. These stones, traditionally reserved for objets d’art and fine jewellery, are reimagined here at architectural scale.

The inherent translucency of certain materials allows for dramatic backlit applications, while others offer density, movement or crystalline sparkle. No two panels are ever identical.

De Ferranti’s Semi-Precious mosaics are exactly that - Precious. Crafted with patience, defined by rarity, and designed for interiors where material storytelling matters.
