Orange Diamonds


(Click to Enlarge)
The largest fancy-vivid orange diamond known to exist sold for 32.6 million Swiss francs ($36 million) at Christie’s International in Geneva in late 2013.

The 14.82-carat pear-shaped stone’s price was about $2.4 million per carat, this was a per-carat record for any colored diamond at a public sale. The "Zoe Diamond" recently sold for $ 3.3m per carat. The gem also set a record for an orange diamond of its type.
The majority of diamonds contain some nitrogen. In orange diamonds the nitrogen atoms have grouped themselves in a very specific way. This happens during and right after the diamond is formed. Nitrogen arrangements absorb light in the blue and yellow region of the spectrum producing an orange color. Orange Diamonds may contain a brown, yellow or pinkish modifying color.

The strength of colour is one of the most important factors in determining the value of a natural color diamond. The value increases exponentially with the intensity of the most prominent colour within the diamond.
Orange diamonds are typically found with a hint of other hues such as brown or yellow; diamonds with a pure vivid orange color are extremely rare and valuable.

The Pumpkin Diamond is 5.54 carats and rated as Fancy Vivid Orange by the GIA. Halle Berry wore the ring to the 2002 Oscars where she won the Academy Award for Best Actress for her role in Monster's Ball.

DeBeers selects Kleven for newest diamond ship

(IDEX Online News) – De Beers has selected Norwegian shipbuilder Kleven to build a tailor-made ship for deep sea mineral exploration off the coast of Namibia.

Kleven said the vessel would be the "first of its kind" and will work on a large area offshore where over three million years the Orange River deposited sediments containing diamonds.
Marin Teknikk says the De Beers vessel will be similar to earlier MT 6022 designs, but the internal arrangement will be different. Below deck and the entire aft deck will be installed with equipment designed for underwater mineral activity. The ship is 113 metres and has a beam of 22 metres. The vessel will be able to operate at depths of up to 150 metres. Up to 80 people can be housed. The ship will be deployed offshore for up to three years at a time, with crew transfers and supplies handled by smaller vessels or helicopters.
The vessel will be built at Kleven Verft in Ulsteinvik, Norway, and is scheduled to be delivered in June 2016.

Gemstones of Elizabeth Taylor

Elizabeth Taylor (February 27, 1932 – March 23, 2011) was married eight times to seven husbands. When asked why she married so often, she replied, "I don't know, honey. It sure beats the hell out of me," but then added, "I was taught by my parents that if you fall in love, if you want to have a love affair, you get married. I guess I'm very old-fashioned."

The Elizabeth Taylor Jewelry Collection set a new world record (by a very large margin) for the most valuable private collection of jewels sold at auction, bringing $115,932,000 in 2011.
La Peregrina is one of the most famous pearls in the world. Its history spans almost 500 years. Richard Burton purchased the pearl at the Sotheby's auction for $37,000. He gave it to his wife, Elizabeth Taylor, as a Valentine's Day gift during their first marriage. The pearl sold for a record price of more than $11 million.
The Elizabeth Taylor Diamond is a 33.19-carat Asscher-cut D color potentially flawless diamond set on a ring that Taylor wore nearly everyday.

It sold for $8.8 million, well above its $2.5 million to $3.5 million estimate.
The BVLGARI Emerald Suite, a suite of emerald and diamond jewelry brought a total of $24,799,000. It was acquired between 1962 and 1967.
The BVLGARI Sapphire Sautoir, set with a sugarloaf cabochon sapphire of 52.72 carats sold for $5,906,500.

This bold Art Deco style sautoir was a gift from Richard Burton for Elizabeth Taylor’s 40th birthday in 1972.
The Taj Mahal Diamond, on a gold and ruby chain, by Cartier realized $8,818,500, setting a world auction record for an Indian jewel.

Inscribed with the name Nur Jahan, the wife of the Mughal Emperor Shah Jahangir, this heart-shaped diamond is believed to have been a gift from the ruler to his son, who became the great emperor Shah Jahan (1592-1666).
The Cartier Ruby Suite, a suite of ruby and diamond jewelry realized a total of $5,403,500.

Comprising a necklace, bracelet and earrings, Elizabeth Taylor’s husband, the film producer Mike Todd, presented her with a trio of Cartier boxes containing this magnificent suite of ruby jewels while she was swimming laps in the pool at their villa in St.-Jean-Cap-Ferrat, in August 1957.
The Richard Burton Ruby and Diamond Ring, of 8.24 carats, by Van Cleef & Arpels, was a gift from Richard Burton, Christmas 1968. He had promised to buy Elizabeth Taylor a special ruby, with perfect red color, “But it has to be perfect”, he warned.

Four years after making his promise, he tucked a small box into the bottom of Elizabeth’s Christmas stocking – so small that she missed it when opening her gifts. This ring achieved $4,226,500 setting a record for a ruby per carat ($512,925).
The Night of the Iguana Brooch, by Tiffany & Co. sold for $1,202,500. More catfish in form than iguana, Richard Burton gave the brooch to Elizabeth Taylor to wear to the star-studded premiere of his film The Night of the Iguana, in 1964.
