EmmaJane Knight meets Sonia Petroff
We are honoured to present a selection of looks from our 2026–2027 Ladies' Cashmere and Tailored Clothing Collection accessorised with pieces loaned from the iconic house of Sonia Petroff — a pairing that feels both natural and intentional.
Sonia Petroff is an accessories brand of timeless belts and jewellery, handcrafted in Italy. Vintage inspired by the archives of the accessory’s designer Sonia Petroff, who was one of the most respected accessories designers of the twentieth century,
Sonia Petroff worked from the 1960s until her retirement in 1990. A Bulgarian aristocrat who fled Europe during WWII, she made her home in Rome, where she designed for Valentino, Balmain and Nina Ricci, as well as for a discerning private clientele across the globe. Drawing on nature, the Mediterranean, mythological symbolism and art history, her bold, joyful pieces were crafted by Roman artisans and coveted by the international jet-set.
Her archive passed to her niece by marriage, Maria Leon-Sceti, who relaunched the brand in 2018 and continues to lead its bold aesthetic vision today — ensuring that Sonia Petroff's singular eye remains very much alive. Each piece is handcrafted in small artisan studios in Italy 🇮🇹, using the highest quality materials (24k gold overlay on brass with Swarovski crystals, resin, glass and enamel stones) with impeccable attention to detail.
Sonia Petroff's creations have recently been exhibited alongside masterworks in Colnaghi's London gallery, the world's oldest commercial art gallery, celebrated for centuries of expertise in Old Master paintings, drawings and antiquities, and renowned for presenting museum-quality works to collectors and institutions worldwide. That such a gallery chose to place Sonia Petroff's creations in dialogue with its collection speaks volumes: both traditions trace the evolving language of adornment — as a marker of status, identity and devotion, and as an expression of the highest technical and artistic ambition.
The same spirit of uncompromising craftsmanship runs through everything we do at EmmaJane Knight.
We believe the woman who collects Colnaghi, who wears Sonia Petroff, is the same woman who understands that true worth is born of provenance, patience and extremity. In Mongolia, cashmere is never described as luxury — a word used too carelessly in fashion, implying excess rather than merit. It is called precious. Of genuine worth. And there is a profound difference. Worth is something earned — by the animal, the herder, the land, the craftsman — at every stage, long before the fibre reaches a spinner's hands. Our cashmere is sourced from the world's finest sustainably certified mills — Cariaggi in Italy and Todd & Duncan in Scotland — and directly from the Mongolian and Chinese heartlands where the finest raw fibre originates, on the steppe where the Capra hircus goat endures winters of minus 40 and summers of plus 40. It is that very extremity of climate that produces the miracle of the fibre: the colder the winter, the finer the undercoat the animal grows to survive it. The harshness of the landscape is precisely what creates the softness in your hands. This is cashmere that has been earned at every stage before it reaches you — and it is that integrity of origin, that accumulation of worth, which sits at the heart of every EmmaJane Knight piece.
