Set in the heart of Mayfair, the former US Embassy is an iconic landmark Sophia Hirsh passes on her walk to the townhouse each day, making this a project that feels especially close to home. There is also a natural connection between the building’s American heritage and Hirsh’s own transatlantic roots bringing an added sense of meaning to the collection. 

Named after the Greek goddess of light and brilliance, Thea explores flowing curves, sculptural forms and talon-inspired details that gently cradle gemstones in mid-air. The collection balances strength with elegance, reflecting both the architecture of the building and the symbolism of the eagle itself — protection, vision and freedom.

Entirely handmade in our Mayfair atelier, the collection includes polished gold designs alongside diamond and colour gemstone pieces in 18K yellow gold, platinum and 18K rose gold. Each piece reflecting our passion for British craftsmanship and exceptional natural gemstones. Discover the collection online below, at the Asaya Boutique at The Chancery Rosewood, or book an appointment to see it being created in the Hirsh atelier.

We are an independent family-owned jeweller based in Mayfair, London, founded in 1980 and now led by second-generation owner Sophia Hirsh. Guided by a passion for British craftsmanship and exceptional natural diamonds and rare colour gemstones, each piece is handmade in our Mayfair atelier at 46 Conduit Street.
