Fashion pundits may well be predicting a rise in the sales of sapphires following Prince William’s choice of engagement ring for Kate Middleton, but diamonds will always have an irresistible allure. Should the future Princess Catherine be hankering after a stunning rock (or two) then His Royal Highness could always splash out and buy the Steinmetz Yin Yang – the World’s largest pair of identical cut diamonds – which were unveiled earlier today at the Guggenheim Museum during Bloomberg Link’s Hedge Funds 2010 event.
The spectacular stones weigh 35.61 and 35.77 carats respectively and were cut from two individual rough diamonds, each initially weighing over 100 carats, which were discovered in Southern Africa, and cut by Steinmetz, creators of the world’s finest diamonds. The resulting gems are Flawless both internally and externally of the highest colour D colour and are also Type IIa, a classification reserved for less than 2% of diamonds in the world.
“More than a year was spent by a team of Steinmetz craftsmen to finish the perfectly matched pair of Round Brilliant cut stones” commented Nir Livnat, Chairman of Steinmetz Diamonds, “We strive to have the rarest most beautiful diamonds available in the marketplace.”

The historic diamonds are likely to be destined for the collection of a true connoisseur. According to market specialists, these rare gems are likely to value in excess of $25 million and are available for sale through Sotheby’s Diamonds, the partnership between esteemed auction house Sotheby’s and Steinmetz Diamonds. That’s supposing they aren’t bought a private client first; the Bloomberg Link Hedge Fund event was attended by some 300 international financiers and investors who gathered to hear talks from influential industry figures. If one them wasn’t tempted to blow their bonus then we can’t think of a more perfect owner for these peerless stones than the future Queen of England. After all, nothing says I love you quite like a diamond.
