The gemstone has excellent quality characteristics. The color of this diamond is Fancy Vivid Pink by the Gemological Institute of America, and IF is clarity. This diamond is classified as a rare type IIa. It was cut from a 132.5 carat diamond mined by De Beers in 1999 in Australia

It took about 20 months to cut the stone. For the first time this diamond, under its old name "Steinmetz Pink", was shown to the public in Monaco in 2003. This Pink diamond has previously been exhibited at Sotheby's in November 2013 in Australia. Then he left for a record $ 83 million. But at the end of February 2014, it became known that the buyer could not pay for the diamond and the Sotheby's auction bought the stone for himself for $ 72 million. At the moment (December 2019), this is the largest and most expensive pink diamond sold at the auction. Also the CTF Pink Star is the world's most expensive gemstone ever sold at auction.

A 24.78-carat, rectangular, stepped-cut, rounded pink diamond was sold in November 2010 at Sotheby's in Geneva for $ 46.1 million ($ 1,860,000 / carat).

The history of this unique stone can only be traced back to the middle of the last century. It is not known for certain where and when the diamond was mined and cut. The first famous owner of the diamond was jeweler Harry Winston, who sold it to a private collector about 70 years ago. From then until this auction in 2010, the stone has never been put up for auction. It is now known that Lawrence Graff re-cut the acquired "The Graff Pink"... The new value of the stone mass is 23.88 carats, the loss was only 0.90 carats. At the same time, the risk of re-cutting the most expensive stone (at that time) sold at the auction turned out to be justified. The new GIA re-cut stone certificate now lists a more valuable color, Fancy Vivid Pink diamond, and has a clear IF. According to some estimates, the value of a jewel with such updated characteristics has increased by more than $ 10 million. In 2010-2017. this diamond was the most expensive pink diamond sold at the auction.

The diamond from which the "Little Prince" was cut was mined over 300 years ago at the famous diamond mines of Golconda in India.


One of the owners of the stone was Osman Ali Khan, the ruler of Hyderabad, who was voted the richest man in the world by Time magazine in 1937. But after World War II, his financial situation deteriorated and the diamond was put up for sale at Sotheby's in 1960, where it was acquired by the jewelry house Van Cleef & Arpels. The diamond got its name in honor of the 14-year-old prince of Australia, who was present with his mother Maharani Sita Devi at the celebration of the purchase in the Parisian store Van Cleef & Arpels. The price reached in the auction makes this diamond the most expensive diamond from Golconda ever sold at auction.

The preliminary cost estimate of the stone was $ 28-42 million. The buyer remained unknown. Stone color - Fancy Vivid Pink (fancy bright pink), clarity - VVS1. The stone is classified as a rare type IIa diamond. The original owner of the stone was Stephen Silver, a passionate Australia gemologist and jeweler who bought the diamond in 2013. The weight of the stone was then 16.21 carats, and the color was Fancy Intense Pink (fancy intense pink). Stephen suggested that if the stone was re-cut by changing its cutting parameters, then the color of the stone could become even brighter.

It was a space reserved for domestic workers, located on the top floor of an old building in Ostend. Small windows, dark rooms, completely obsolete. Until Iris and her companion stumble upon it… With their architect, they drew up Bathroom renovation plans. And for the bathroom, they trusted Van Marcke.“The location was fantastic, as for the apartment it had huge potential,” “This is an old apartment building with a wide facade and sea view. When we bought, we knew what we were getting into: there was going to be quite a bit of demolition work.

This thought remained until I started working with an Business accounts package. Different booking rules had to be created per event. And for some reason, accounting packages are ready to support any multinational, but it is far too complex for an average self-employed person.Curious as I am, I started researching why accounting is so difficult. The reason was quickly found. Traditional accounting, or the 'double accounting method', dates from the 15th century. Conceived by the Italian monk Luca Pacioli. In those days, bookkeeping was still a quill pen. Then it was useful to work with diaries, journal entries and ledgers. With the double accounting method you can spot errors and check the books afterwards. A nice system for that time. With the introduction of the computer, the unfortunate c…
