There are people who design jewellery and then there are jewellery designers like Lo Kai-yin. Given her stature as author, scholar and Chinese cultural consultant, it's no surprise bigwigs attended the sale of Lo's latest semi-precious stone collection at the weekend at the China Club. Among the guests were Timothy Fok Tsun-ting, Carrie Lam Cheng Yuet-ngor, and Chief Executive Donald Tsang Yam-kuen and his wife Selina Tsang Pou Siu-mei (with Lo, left). 'I'm a historian-turned-designer,' Lo said. 'So my interpretations and instincts are from a historical awareness and appreciation of Chinese culture. I was the first to interpret the cultural past in a contemporary sense, making history wearable.' Lo has patrons worldwide and her works are frequently shown in museums (such as the Guggenheim Hermitage Museum in Las Vegas) yet she eschews branding herself a commodity. She has no time for celebrities who call themselves designers. 'This is a celebrity craze. Most of them launch their so-called jewellery as a drive for augmenting coverage. To me, sustainability is most important. Last December I was at the Metropolitan in New York and I saw someone wearing jewellery I designed 15 years ago. That pleased me, to know people keep my work as collectibles.'
