ABOUT US

DOSIS G6C is a London-based, family-run jewellery house where heritage and modernity entwine. The name “DOSIS,” drawn from dose, reflects precision, balance, and clarity—principles that guide every creation.

At the heart of the brand is Guan Beichen, a Central Saint Martins graduate whose designs embody both romance and rebellion. Beneath the refinement of high gemstones lies a fiery spirit—her work a reflection of the struggle for balance beneath society’s masks, and ultimately, a journey to remain true to oneself.

Her training spans master goldsmithing traditions across Asia: filigree inlay at the Palace Museum in Beijing under Master Xian Xiuying, participation in China’s first national intangible cultural heritage project, and the near-lost art of royal granulation engraving in Tokyo with Master Sakamoto at Mikimoto. These rare techniques shape her signature style—where cultural depth meets contemporary emotion.

The house is further supported by family associate Ms. Yang Yuan, a GIA-certified gemologist with extensive international experience in luxury jewellery. Her expertise ensures that every DOSIS G6C creation is realised with uncompromising excellence.

Together, they shape DOSIS G6C into more than a jewellery brand—it is an intimate pursuit of beauty, balance, and authenticity, expressed through jewels that resonate deeply with modern life.
