Our News
Full Speed ahead for the New Year!
Dear Customers, Readers, and Friends,

2013 is drawing to its close and you have once again rewarded us with your loyalty for the care with which we choose our Natural Fancy Coloured Diamonds. We thank you and look forward to our continuing cooperation.

This year has been very successful for the mobile library for children. Thanks to the pragmatism, foresight and great personal commitment of all those involved, the project is moving forward in India and we will continue to lend our support through this year’s donation.

The trend indeed started recent years, but the rapidly growing interest in Natural Fancy Coloured Diamonds today could almost be called “Fancymania”. 2013 was also the year of spectacular Natural Fancy Coloured Diamonds that captivated the public and attained fantastic prices at auction.

But without going to such extremes, perfectly cut, small “fancies” fascinate us just as much when set in imaginative creations.

We are already preparing for
INHORGENTA MUNICH where we will be present from 14 – 17 February 2014 with our complete collection. We will also be featuring our new colour card!

With this December newsletter, we would like to extend our very best holiday wishes. We also wish you a successful end to your annual accounts and a great start for 2014.

Here’s to yet another year of successful collaboration!

The Mobile Library – From a Motorcycle to a Tata ACE
In Newsletter No. 9, we reported on the unusual project undertaken by the Regenboog India Foundation. The idea was to convert an autorickshaw into a mobile library for children and young adults, replacing the previously used motorcycle.

During the planning stage, however, it quickly became clear that even an autorickshaw would not adequately protect the books during monsoon season. Therefore, it was decided to acquire a used pickup truck, a Tata ACE, and convert it into a “book-bus”.

Once again this year, we have decided to support this undertaking with our donation. We know that all the donations will be used to fund the projects because the association’s staff is made up of volunteers!

From Our Collection:
Single and Paired Stones in a Hearts & Arrows Cut
This time from our collection, we would like to present several champagne coloured single stones, as well as pairs. All the stones have been cut in the style known as Hearts & Arrows.

In this number, read our article “The Brilliant Cut” (part 4) to learn more about the Hearts & Arrows cut.

Due to their identical appearance, Hearts & Arrows cut diamonds are perfect to use together as pairs in matching pieces. The opposite picture shows a pair of champagne coloured diamonds in a C3 shade, weighing a total of 2.11 ct.

If you are interested in these stones or other pairs or single stones in the Hearts & Arrows cut, do not hesitate to contact us at:

All about Natural Coloured Diamonds
From the Steinmetz Pink to the Pink Star to the Pink Dream
The eagerly awaited highlight of the Sotheby’s jewellery auction held in Geneva on 13 November 2013 was the 59.60 ct oval Pink Star diamond.

The Pink Star belongs to the Type IIa diamond group, the chemically purest type of diamonds that usually present outstanding optical transparency. The Pink Star has received a flawless, Fancy Vivid Pink grading by the Gemological Institute of America (GIA) and is the largest pink diamond ever graded by the GIA. For David Bennett, president of Sotheby’s European jewellery department, the Pink Star is one of the earth’s greatest natural treasures.

This diamond was found in 1999 by De Beers in South Africa and the rough stone weighed 132.50 ct. The exact location where the stone was found is not known. Steinmetz Diamonds cut and polished the stone for 2 years and called it the Steinmetz Pink. After it was sold in 2007, the new owner renamed it the Pink Star.

The diamond was presented to the public for the first time in Monaco in 2003 before being shown at the Smithsonian Institute in Washington D.C. as part of the “Splendor of Diamonds” exhibit. From 2005 to 2006, it was the star attraction of the Diamonds exhibition at the Natural History Museum in London.

Before the auction, the value of the Pink Star diamond had been estimated at the incredible amount of USD 60 million. After just 5 minutes, the auction was already finished. New York diamond cutter Isaac Wolf won the auction with his incredible bid of USD 83 187 381 (USD 1 395 761 per carat) – the highest price ever attained at auction for a gemstone, a colourless diamond or a Natural Fancy Coloured Diamond. The Pink Star has since been renamed the Pink Dream by Isaac Wolf.

The Orange - The Biggest Fancy Vivid Orange Diamond in the World
On 12 November 2013, Christie’s auctioned off a spectacular orange diamond during its Magnificent Jewels sale in Geneva. The Orange, a flawless, Type IIa, pear shaped diamond which weighs approximately 14.82 ct, is the largest pure orange diamond in the world. It is also the largest of its kind ever offered at auction. The Gemological Institute of America (GIA) emphasizes that cut diamonds with a Fancy Vivid Orange colour grading rarely weigh more than 3.0 – 4.0 ct. The Orange weighs four times more! 

Pure orange diamonds are also known as “fire diamonds”. This name was introduced by the gemmologist Edwin Streeter in his book The Great Diamonds of the World (1882). To date, the last pure orange diamond sold at auction was the 5.54 ct Pumpkin diamond which was auctioned off by Sotheby’s for USD 1 300 000 in 1997.

Before the auction started, the diamond’s value was estimated at USD 17 – 20 million. A private collector, who was physically present for the sale but initially wished to remain anonymous, bought The Orange for USD 35 540 611, which amounts to USD 2 398 151 per carat. Thus, two new auction records were set: the highest price per carat ever paid for a diamond and the highest price ever attained for an orange diamond.

Argyle Pink Diamonds Tender 2013 - "Red Edition"
In Newsletter No. 16, we reported on the stars of this year’s Argyle Pink Diamonds Tender. Bids could be submitted up to 2 October and the outcome was eagerly awaited by all. And the results greatly exceeded all expectations!

All of the 64 pink, red and blue diamonds, ranging in weight from 0.20 ct to 3.02 ct, were sold and many of them for more than the price estimated before the auction. Compared to previous years, a certainly record number of bids exceeded USD 1 000 000.

The highest bids for the two stars of the auction even broke the 2 million dollar mark. The 1.56 ct Fancy Red Argyle Phoenix diamond reached the highest price per carat ever attained at an Argyle Pink Diamonds Tender. The winning bid for the 2.51 ct, Fancy Deep Pink Dauphine diamond broke two records, being both the highest price ever attained for an Argyle diamond and the highest price ever paid worldwide for a Fancy Deep Pink diamond. Rio Tinto, the Argyle Mine operator, has, however, not released any specific figures.

For Jean-Marc Lieberherr, managing director of the diamond division, these excellent results reflect the increasing demand for Natural Fancy Coloured Diamonds among top jewellers, designers and collectors.

Chopard’s Wonderful World of Animals
Chopard, the famous, traditional Geneva based jeweller, showed daring and creativity with its 2010 animal collection. Unique pieces of jewellery, all dedicated to the animal theme, were especially created to celebrate Chopard’s 150 th anniversary.

Large and small animals of all kinds were present in the shape of bracelets, necklaces, brooches, earrings and rings. This original, humorous and masterful collection is, to date, the most versatile collection of jewellery Chopard has ever designed for a specific theme.

Our Gift Recommendation
Masters of Dreams
Do you ever ask yourself how the stunning creations of gold, diamonds and gemstones that adorn stars and celebrities come to be? Would you like to know who those creators are, where they find their inspiration and how this jewellery is made? Then you will love the film Masters of Dreams.

In this four part documentary, thirteen of the most famous jewellery houses, including Boucheron, Buccellati, Bulgari, Chaumet, Chopard and Damien, allow viewers a glimpse inside the fascinating world of fine jewellery. With Masters of Dreams, the filmmakers Guillaume De Ginestel, Eric Ellena, Jane Lipman and Sean O’Sullivan have produced an impressive piece. The DVD is available in English and French.


The Queen’s Diamonds
The author of this entertaining, illustrated book, Sir Hugh Ashley Roberts, British art historian and exhibition curator, was Director of the Royal Collection from 1996 to 2010. The Queen’s Diamonds is the first book on the history of the royal diamonds authorized by the Queen.

Fantastic photographs, in part on over-sized double-paged spreads, show the diamond jewellery of British queens from 1830 until today. The reader is informed in detail about the origin and the history of each piece of jewellery and learns, along the way, many interesting things about the British royal family.

This book is available in German (ISBN-10: 3836927489) and in English (ISBN-10: 1905686382).

The Brilliant Cut – Part 4: Hearts & Arrows
In part 3 of our series, we presented the various “ideal” brilliant cuts as being the result of theoretical calulations based on the diamond’s optical and physical properties.

Based on these calculations, a distinctive feature became apparent: the Hearts & Arrows cuts.
