An exhibition featuring one of the largest cut black diamonds in the world has opened in London.
Wallace Chan: The Wheel Of Time is being held at Christie's auction house in St James's to honour the 67-year-old artist's five-decade career.
Among the work on show is the Legend Of The Colour Black, a black diamond shoulder brooch sculpture.
The centre stone of the piece is one of the largest cut black diamonds in the world, weighing 312.24 carats (62.45g).
The exhibition, said to be the largest of Chan's work in Europe, features 150 pieces of his jewellery, alongside six titanium sculptures.
Its title serves as a metaphor for the artist's labour-intensive working process, requiring meticulous attention to detail and embracing Chinese aesthetics, Christie's said.
The majority of the pieces on display are on loan from Chan's many international collectors.
"In the blink of an eye, half a century has flown by," Chan previously said.
"Time is an eternal wheel that rotates for infinity with neither beginning nor end. In the creative process, time is a theme so intangible, yet omnificent."
The free exhibition will be open until 10 September.
