Simple and minimal, yet luminous and glamorous, the Asprey 167 Button Pendant has been in the Duchess’s jewelry collection for many years now. She was photographed wearing it before her engagement, during a time when she was working for the company Jigsaw.
According to the company’s website, they used “the iconic 167 New Bond Street Button”. The pendant has a “central amethyst stone, surrounded by pave diamonds, all set in 18ct white gold”. The chain it is on is also made of white gold.
The current retail price is $4,000.
Here it is on Kate during the Royal Tour of Canada in 2011.
