Sotheby’s Australia will be auctioning off a very rare red diamond in Sydney on April 12th, 2010, at its very first Australia-based auction. The collection will include more than 250 lots of antique and contemporary jewelry. Presale estimates range from $3.5 million to $4.7 million.
Not too many people know that pink and red-tinted diamonds most often come from Australia, from the renowned Argyle mines. The natural highlight of the entire sale is a fancy purplish-red Argyle diamond ring. This eye-catching piece has a presale estimate of $642,000 to $916,000. Rare red diamonds like this are hardly ever auctioned, and it is the first of its type to be auctioned off in Australia, coming with an authentic letter from Argyle attesting to its rarity. Coming to weigh in at 0.82 carats, the stone is couched between a pair of blue diamonds in round brilliant cut and several sparkling diamonds in glamorous pave settings.
Also under auction are a double strand of graduated emerald beads (amounting to almost 176 carats), which are also highlighted by diamond set rondelles. A sapphire and diamond ring are to be sold, as well as a 5.52 carat emerald and diamond ring. And it’s not only diamond jewelry that’s up for sale, but also watches from the likes of Rolex, Piaget, Cartier, and Breitling. And finally there’s a special but unusual addition to the auction: a must-have Vertu ‘pink diamond signature’ mobile phone. Better not lose it!
