The Flawless Blue Diamond from the Cullinam Mine in South Africa
A rare blue 7.03-carat blue diamond was cut from a larger 26.6-carat rough gem by the Jewel Firm called Petra, who discovered this jewel at its Cullinan Mine in South Africa. One of the rarest of all gemstones, this exquisite blue diamond with a vivid and brilliant blue gets its color from the chemical “impurity” called boron during the time of its formation. According to David Bennet, the head of Jewelry at Sotheby’s:
David Bennett – “This stone certainly ranks among the most important blue diamonds that I have had the privilege of offering for sale in my career at Sotheby’s.'What makes it particularly special for us, is that we’ve been able to follow its production from the initial rough state through the various stages of its cutting and polishing.”
Blue diamonds are the rarest of all gemstones, for its boron enriched color blue. According to Sotheby, the Cullinan Mine is the world’s most consistently reliable source of blue diamonds.”
Because of the world economic slump in 2009, the price of precious stones cratered 15% in the first six months of the year as demand slumped. In response to the market, the world’s largest diamond producer, De Beers began to close several of its mines. It was also reported that Harry Winston Diamond Corporation shut down its Diavik Mine in Canada.
The selected elite rough diamond handlers like Petra who traditionally sold rough diamonds to other cutting and polishing houses, were in this bear market cutting out the middle man and marketing the gemstones themselves. In October 2007, Sotheby’s sold a vivid 6-carat blue diamond in Hong Kong in October 2007 for a then record $1.32 million per carat. In December 2008 the world’s most expensive blue diamond, the 17th century Blue Wittelsbach Diamond sold by Christie’s for $24.3 million.
It was reported that Petra got $9.48 million at a sale in May for this polished 7.03-carat blue diamond gemstone from the Cullinan mine, that also set a per-carat record for blue diamonds.
The symbolic power of the tzit-tzit evoked the power of the Torah with its identity with the priesthood and the nobility. It elevated this color with the imagery of the Divine with its inclusion as representing the 613 commandments of the Torah that were given for all of Israel to keep. Even the Hebrew peasant who wore one blue thread in a tassel on each of the four corners of his garment would feel elevated as they also were part of the noble and royal race of Israel.
This blue colored dye which in Hebrew was called, Tekhelet, was extracted gland of the Murex trunculus, a snail in the Mediterranean. When put under the modern spectrograph of the scientist, the visual length of the spectrum of the sapphire blue would come to exactly 613 nanometers of light.
Was it not amazing that the exact details given by the L-rd of hosts sitting on the Throne of G-d over a crystalline blue platform of sapphire became the ultimate mystical experience of Oneness with the Divine. They would always be reminded that it was He who gave them the 613 commandment to keep and by looking at the colored blue thread which has a spectrum of 613 nanometers of light on their tzit-tzit, would remind them of the 613 commands that they were to remember.
