Why diamonds are Hong Kong jewellery designer Nicholas Lieou’s best friend
- The designer has teamed up with Sotheby’s Diamonds to produce fine jewellery with a new generation of clients in mind
- The special collection includes transformable pieces and designs based on nature

How did your partnership with Sotheby’s Diamonds come about? “I had wanted to work with Sotheby’s Diamonds for a while and then they approached me. It was mutual. They showed me their diamond selection and I sent them a few designs.
“I wanted to start with nature. I started from seeds and pods; that’s where a lot of the shapes come from, like this ring in the shape of a cocoon that encapsulates a green diamond.”
High jewellery is often associated with big pieces and older customers. What are you doing differently?“High jewellery can be very heavy. Those necklaces are beautiful but difficult to wear and meant for special occasions. I tried to make this collection more ‘everyday’, items that people can wear casually. Normally you don’t wear a six-carat diamond during the day but I wanted to do something modern. Some pieces are transformable to give options.”
Were you aiming to speak to younger customers with this collection? “Yes, this collection is for the next generation. The older generation tends to want things more fussy. It’s an old-school way of thinking: if I have a lot around the stone it makes it worth it, so it’s more gold and more labour involved.”

What’s your favourite stone? “I do love diamonds. My work is very black and white and clean so I feel diamonds suit that. My aesthetic is clean but my lines are soft and smooth, sinewy. I don’t like sharp corners. I feel that when you put jewellery on, it needs to go with the body’s curves. Sometimes when it’s too angular it can look cool but you have to be a certain character or in a certain mood to pull it off.”
