About Maison Katerina Sibilia

Maison Katerina Sibilia creates fine jewelry carrying meaning, revealed by light.

Maison KATERINA SIBILIA is a London-based fine jewellery maison founded by Katerina Freuchet Sibilia, GIA gemologist and former De Beers executive.

Built for those who seek more than adornment, the Maison creates fine jewellery as personal talismans - symbols of identity, memory, and personal growth. Each jewel is designed around duality: timeless elegance in daylight, then a hidden message revealed under ultraviolet light.

The DNA of Maison KATERINA SIBILIA sits at the intersection of gemological expertise, design, high-end artisanal craftsmanship, and innovation. The Maison honours the old way of jewellery creation - skilled hands, rare gemstones, and uncompromising quality - while challenging the long-established codes of luxury through designing with fluorescence.

As a modern luxury Maison, KATERINA SIBILIA is building fine jewellery for a new generation of clients: emotionally meaningful, meticulously crafted, and priced with intention through a lean, direct, founder-led model.
