“The 1927 Cartier bracelet from Sotheby’s Magnificent Jewels and Noble Jewels sale in November 2019. It had a 47.07-carat, royal-blue Burmese sapphire and I was honoured to bid on behalf of a client from Asia. It went from US$2 million to US$5 million in just two minutes. After a battle that lasted almost half an hour, it was sold for over US$6 million.”

“A beautiful cushion-cut, 31-carat Sri Lankan sapphire was auctioned by Christie’s in Geneva in 2011. I almost bought it but at the very end the price shot up and I had to bail out. I will never forget it.”
