Dr Xiong launches her LGD brand ‘PureVivid’ at the National Wedding Show, London

Dr Xiong, inspired by her experience and China’s untapped potential, launched her lab-grown diamond brand, PureVivid, last year. On April 12, she showcased her brand at the National Wedding Show in London — the largest consumer wedding event. It was the only Chinese brand among over 2,000 exhibitors.

The story goes like this …Ten years after getting married, Dr Xiong Lan and her partner decided it was time to upgrade their diamond wedding ring. They initially turned to a household name—De Beers, the iconic British diamond brand. However, what they discovered was startling: a three-carat natural diamond was priced at nearly £80,000, equivalent to a down payment on a property in China. That’s when a friend introduced her to lab-grown diamonds.

In the end, Dr Xiong ultimately chose a 5-carat lab-grown diamond, paying less than 40,000 RMB (approximately £4,300)—a fraction of what she would have spent on a natural diamond of the same size. Dr Xiong’s choice highlights the rapid development of the lab-grown diamond market globally in recent years, with China leading in production.
