The Moussaieff Red

The William Goldberg Diamond Corporation, famous for outstanding stones like the Premier Rose and the Guinea Star, cut this gem from a 13.90 ct. rough. They transformed the piece into a spectacular red diamond weighing 5.11 ct. The Gemological Institute of America states, "It is the largest Fancy Red, natural colour diamond that we have graded as of the date the report was issued."

Originally named the “Red Shield,” the Moussaieff Red is a triangular brilliant-cut or trilliant-cut, fancy red (ruby red), internally flawless (IF), 5.11 carat diamond. It is the largest red diamond in the world today, and its estimated cost in the year 2001/2002, when it was acquired by its current owner Moussaieff Jewelers Ltd., was 8 Million USD. That is almost 1.6 Million USD per carat. Following its sale to Moussaieff Jewelers, the diamond was re-named the “Moussaieff Red." The diamond was discovered by a farmer in the Abaetezinho River, at the Alto Paranaiba region of Brazil during the 1990s.

In 2003, the Moussaieff Red was displayed at the "Splendour of Diamonds" exhibition at the Smithsonian Institute in Washington, D.C.




The Hancock Red

In 1980 the highest auction price paid for a diamond was $127,000 per carat for a 7.27 ct. pink diamond. That record was shattered in 1987 by the first high quality red diamond to be sold at auction, the round, brilliant cut 0.95 ct. Hancock Red. The stone, classified as fancy purplish red was said to originate from Brazil and it sold for $880,000 - that's just a touch over $926,000 per carat!

The Hancock Red was sold by the heirs of the American owner, Warren Hancock, a Montana rancher and diamond collector. Mr. Hancock had bought all his diamonds at retail prices from his local jeweler, and he had reportedly paid $13,500 for the 0.95 carat red diamond in 1956. It is fair to say this was one of the greatest gemstone investments of the century.




The De Young Red

The De Young Red diamond is a 5.03 ct. round brilliant cut stone that is red with a slightly brownish hue. The main kite-shaped facets on the crown are horizontally divided in two, giving the stone slightly more brilliance than a standard round brilliant.

The stone is named after onetime owner Sidney De Young, a Boston jeweler who owned the diamond for quite a long time and eventually would donate the diamond to the Natural History Museum of the Smithsonian Institution, in Washington DC.

Due to the brownish hue in this red diamond it appears to look more like a fine garnet. The stone had actually been acquired by De Young's company as part of an estate sale later where the item had been described as a garnet hat pin.

One day, De Young examined the garnet hat pin and noticed the so-called garnet just did not look quite like a garnet. He also observed that for an old stone it was very clean and free of scratches. This observation aroused his suspicions and he took the stone to be tested. De Young’s instincts were correct; the ‘garnet’ wasn’t a garnet at all but rather a red diamond.




The Kazanjian Red Diamond

This stone belongs to an extremely small and select group of diamonds. It is one of only three red diamonds known to exist in the world today weighing in at 5 carats or more. The other two being The Moussaieff Red at 5.11 ct and The De Young Red at 5.03 ct.

Discovered around 1926 this was originally a 35 carat stone thought to be black bort (poorly crystallized diamond material used for industrial cutting and abrasion) and was sold for a paltry £8 per carat. The stone was sent to Amsterdam to be cut by the firm of Goudvis Brothers. Once cut down to 23 carats it began to sport a brown colour. The cutter continued until finally the stone was down to an emerald cut and deep ruby red colour weighing in at 5.05 carats.

Its rarity makes putting a value on it a challenge. Despite of its unique and beautiful red colour, this diamond has at times been given a surprising lack of respect, with many an untrained eye misidentifying it as a ruby. The greatest danger to its existence came when it was confiscated by the Nazis during World War II. Surviving the war, it was returned to its rightful owner only to be sold repeatedly until disappearing from public view in 1970 for 37 years.

But this stone’s story has a happy ending, for it eventually found its way into the hands of a benevolent owner who uses the stone’s celebrity to promote and finance humanitarian causes throughout the world. Douglas Kazanjian is the 3rd generation owner/operator of Kazanjian Bros., a Beverly Hills, California gem and jewelry firm. When the stone resurfaced in 2007 it was offered to the firm and was at the time unnamed. They bought it, named it the Kazanjian Red Diamond to pay homage to the family legacy and the company's founders.

It now has a noble role as part of the Kazanjian Foundation, est. 1957, to help charities including those that work with disadvantaged children and underprivileged youth. It is displayed around the world, with other famous gems and jewelry, to raise money for the foundation.




The Supreme Purple Star

This stone is surrounded in mystery. According to British Press reports, this rare cranberry-coloured diamond surfaced in London sometime in 2002. The diamond was graded by the British Gemological Institute in London. It is believed to be one of a kind and originated in the Amazon basin.

Its uniqueness seems to lie in the reports that say the colour goes from a deep purple to a deep to vivid purplish red when you look at the diamond from one way and slowly turn it. The weight is reported to be between two and five carats. Some speculate it is more likely between four and five carats and it is believed that the collector was unaware of the rarity of the stone when he took it to a London appraiser.

The owner will have the stone graded by a major laboratory with plans to sell the stone. The clarity appears imperfect from photographs. Some speculate this diamond may be rarer than a red diamond and might sell for more on a per carat basis. Others contend it is worth less than a red diamond. The owners are hoping the diamond will fetch about $4 million per carat. Whatever became of the stone is unknown.




The Rob Red

What makes this tiny red diamond (presumably found in Brazil) so notable? At 0.59 ct is it really worth reading about? Absolutely! It's the saturation of colour that makes natural fancy coloured diamonds so unique and special. Seeing as red diamonds are the rarest of all coloured diamonds, it makes sense that finding a red diamond with the the most saturated red colour would be extra special. That would be the Rob Red diamond.

The pear-shaped, 0.59 ct., VS1 clarity stone named after its owner, Mr. Robert Bogel, has been described by fancy colour expert Stephen Hoffer as “the most saturated and purest red diamond measured visually and instrumentally to date in the world.” and is the only red diamond in the world with the highest colour grading of Fancy Intense Red. In respect of colour saturation and clarity, this stone is unique among all red diamonds.
