A rare pink diamond could set a new record when it goes up for auction in Geneva next week.
The stone, which has been named Fancy Intense Pink, is currently presented as an emerald cut diamond ring and Sotheby's has estimated that it is worth around $27 million (£17 million).
It was sold by renowned American jeweller Harry Winston 60 years ago and has been kept in a private collection until now.
A star attraction at the upcoming auction at a luxury hotel in the Swiss city on November 16th, the item is predicted to overtake most valuable jewel ever to go under the hammer, the Wittelsbach blue diamond, which fetched $24.3 million in December 2008 at a sale held by rival auction house Christie's.
Thaindian News recently reported a diamond encrusted pen sold at an auction in Visakhpatnam, India for 2.3 million rupees (£32,000) in October.
The pen was said to have been made by six craftsmen and was embellished with 2,500 stones encased in white gold.
