As Time goes by
Dear Customers and Readers, Dear Friends,
How quickly time flies! A busy summer draws to an end and it has already been one year since Severin Keller, our intern, started working with us here in Berlin. Today we look forward to welcoming our newest intern, Janina Roßner, a trained goldsmith, to our Berlin team.
Internet has developed at breath-taking speed. Until not too long ago, Amazon and Co. dominated on-line retail, but today, more and more “Internet  jewellers” have entered the market.
Follow us on our “expedition” into the virtual world of on-line retail and learn more about the self-proclaimed experts and their big promises.
We hope you enjoy your reading,

Juliane Hennig

From Our Collection:
Step-Cut Fancy Deep Brown-Orange (GIA) 0.77 ct Diamond
The step-cut (baguette) is rather unusual for coloured diamonds. Cushion and radiant cuts are much more common as they “hold” the stone’s colour well.
This brown orange diamond, though, doesn’t need any added assistance from its cut as its deep body colour and quiet radiance suffice on their own. This is a beautiful and interesting ring stone whose muted brilliance would make it perfect for a piece of men’s jewelry.

All about Natural Fancy Coloured Diamonds
A Butterfly for the New York City Ballet
On 7 October 2014, Sotheby’s Hong Kong will auction the Ballerina Butterfly brooch designed by the fine jewellery artist, Cindy Chao. The value of the brooch has been estimated between USD 750 000 and USD 950 000.

The Ballerina Butterfly brooch is the latest masterpiece in a series of butterfly brooches Cindy Chao has designed every year since 2008. This lavish piece of jewellery is the result of two years of collaboration between the artist and the American actress, Sarah Jessica Parker. The proceeds from the action will go to the New York City Ballet, of which Sarah Jessica Parker is one of the directors.
The body of the butterfly is made of titanium and 18 carat gold. The wings feature a 26.27 carat Fancy Brown cushion cut diamond, three rough brown diamond slices totalling 47.71 carats, and three pink Conch pearls, all surrounded by 98.09 carats of colourless and fancy coloured diamonds.
HRD Antwerp – New Grading Level
On 15 March 2014, the HRD Antwerp Institute of Gemmology (Hoge Raad voor Diamant) extended its colour grading levels for Natural Fancy Coloured Diamonds with two new degrees of intensity, “Vivid” and “Deep”. HRD describes “Vivid” as being a saturated hue with very high clarity and “Deep” as a saturated hue with decreased clarity compared to “Vivid”. An HRD certificate would read, for example, Fancy Vivid Blue Natural Colour or Fancy Deep Blue Natural Colour.
In this way, the laboratory has adjusted its colour grading to meet internationally recognised standards. The GIA (Gemological Institute of America) already introduced these levels in 1994. The HRD now distinguishes the following levels of colour intensity for Natural Fancy Coloured Diamonds: Faint, Fancy Light, Fancy (no prefix), Fancy Intense, Fancy Vivid, Fancy Deep and Fancy Dark.
The Winston Blue
On 14 May 2014, Christie’s Geneva obtained USD 23 800 000 for The Blue, a flawless fancy Vivid Blue pear shaped diamond, the star of this auction. Selling at almost USD 1 800 000 (1 799 953) per carat, the stone has set a new auction record for blue diamonds. The Blue was purchased by the Harry Winston Company, owned by the Swatch Group since 2013.
According to the GIA (Gemological Institute of America), the stone is the largest flawless Fancy Vivid Blue diamond ever submitted to the Institute. Jean-Marc Lunel, the Geneva Director of Christie’s jewellery department, described the diamond as being absolutely pure externally and internally.
Nayla Hayek, CEO of Harry Winston, has made it her mission to acquire the most desirable and unique gemstones. As soon as Christie’s announced the auction of the Fancy Vivid Blue diamond, she knew she needed to buy it. Nayla Hayek has since changed the diamond’s name from The Blue to The Winston Blue, in honour of the famous jeweller.
On-line versus Off-line
Internet is fast and the development of on-line commerce is too. Until recently, on-line retail sales have concerned mostly consumer goods, but today the luxury goods sector, and thus also the jewellery industry, has become the main focus of on-line suppliers. An article in the Goldschmiedezeitung trade magazine last July shows just how important this topic is for specialist retailers. 

As concerns Natural Fancy Coloured Diamonds, we have taken a closer look at one of the self-proclaimed “Internet Jewellers”

Really Cheaper? Natural Fancy Coloured Diamonds on the Net
In our article "On-line versus Off-line" in this newsletter, we drew attention to the questionable purchasing situation a customer interested in Natural Fancy Coloured Diamonds may unknowingly find himself in on the portals of on-line jewellers.
Let us now take a closer look at what effect the inexperience, or supposed inexperience, of many Internet jewellers can have on prices.
You will receive our next newsletter in December 2014.
