There’s more than a little sparkle brightening up the November gloom in Geneva this week.
Some of the world’s rarest and most valuable gemstones are up for auction, they all command multi-million dollar price tags, but there is one particular diamond that has become the talk of the town.
This stone discovered last year in Angola is so pure and so large that even Christie’s jewellery director David Warren can’t contain his enthusiasm.
To show the diamond at its best, a team of jewellers has worked for over a year, setting the stone into a necklace containing almost 6,000 emeralds and over 800 smaller diamonds.
Unsurprisingly it comes with a hefty price tag. The item is expected to fetch at least $30m (£23m) at auction.
