Well Summer is finally here after a glorious Spring. The purple flush of Jacarandas in Brisbane are always a joy to behold. Christmas is coming up so quickly, and we have had a flurry of exciting new designs this past month which we are excited to see in their complete pieces. Stay tuned for new designs in upcoming newsletters!
Jason's Thought Corner. The Art of Design: Striving for Bling
With the internet and ease of access to so many forms of designs, styles and images it is a real driver for me to produce excellent design.
Most of my clients have been intensively searching online for ring designs for many weeks, or in some cases even years, for that perfect Engagement ring bling. They will have ideas and/or parts of a design they would like to include from browsing, checking and comparing engagement ring designers like Harry Winston, Cartier, Bulgari, Tiffany, DeBeers, etc. Seeing my clients checking their designs really inspires me to perfect our engagement ring designs for them to look the most beautiful, be functional and of course well made within their budget.
This sometimes can be a real balancing act as the images or views shown can be with much larger diamonds (sometimes five carats or more!) and the designs, although pretty, have not been thought out properly to the last detail to accept straight wedding or eternity bands, or to last a lifetime.
With this in mind though, it really makes me smile when my new or old clients come to me with a whole folder of images, dissecting these and coming up with a new one-off design, even if the changes are subtle it really gives me pleasure. I believe the art of design across so many industries and fields drives us all a bit closer to perfection and happiness.

In focus: Diamond Certification
Diamond Certification or Diamond Grading Report
A diamond grading report is essentially a statement attesting to the authenticity of a diamond. It provides a true and accurate statement of the diamonds characteristics and grade based on internationally recognised standards.
A diamond grading report will include a plotted diagram of the diamond and all significant characteristics, cut, colour, clarity and carat weight. The report also describes the diamond's shape, exact measurements and proportions as well as the grades of the polish and symmetry. The report comments on any distinctive characteristics of the diamond, like fluorescence if present, graining, and any imperfections the diamond may have.
A diamond grading report is not a retail monetary valuation of the diamond; it is simply a scientific document that clarifies all aspects of the diamonds individuality.
Retail monetary valuations should be conducted locally as retail values may differ depending on local taxes and margins.

Christie's Geneva Jewel Auction to Highlight Diamonds, PearlsChristie's Geneva will conduct its fall sale of magnificent jewels on November 11, featuring more than 390 lots. The jewelry auction is estimated to achieve a sales total in excess of $80 million. The auction is led by a pair of ear pendants by Bulgari, pictured, set with a 6.95-carat fancy vivid blue diamond and a 6.79-carat fancy vivid pink diamond, with a presale estimate of between $12 million and $15 million.
Rahul Kadakia, the international head of Christie's jewellery, said, "With one of the largest and most important sapphires in the world from private hands, a Bulgari masterpiece, iconic Cartier jewels from the Duchess of Windsor, natural pearls that were once in the collection of Baroness Edouard de Rothschild and Empress Eugenie's Feuilles de Groseillier brooch, Christie's Geneva is proud to present the finest and best jewels in the world on November 11."
Christie's will offer the fourth largest faceted sapphire in the world, the Blue Belle of Asia, a 392.52-carat cushion-shaped ceylon sapphire, with a presale estimate of between $7 million and $10 million. The stone was discovered in 1926 at Pelmadula, Ratnapura. In addition, The Queen of Burma ring (pictured below) will be offered with a pre-sale estimate of between $5.5 million and $7 million, featuring a 23.66-carat, vivid pinkish-red ruby that was mounted by Cartier.
Additional highlights include a pear-shaped very light pink diamond necklace of 40.48 carats with a pre-sale estimate of between $3.5 million and $5.6 million and seven jewels by JAR, some of which were recently on display at the "Jewels by JAR" exhibition at the Metropolitan Museum of Art in New York, including the "Gardenia," the "Parrot Tulip" cuff and a pair of diamond string ear pendants.
Important pearls offered by Christie's Geneva included a piece formerly in the collection of Rothschild, an Art Deco diamond necklace suspends two natural pearls of great quality and exceptional lustre, measuring 16.0mm each for a pre-sale estimate of between $700,000 and $1 million. The sale will also feature a pair of diamond ear pendants with two magnificent drop-shaped natural pearls, weighing more than 100 grains each with a presale estimate of between $2.8 million and $3.5 million.

Debbie's pick of the month
I was recently reminded of this gorgeous piece I designed for the lovely Judd and Lauren, when they returned a little while ago to discuss their wedding bands. Always an admirer of fancy cut diamonds, I particularly like this stunning Trilliant cut for its rarity. Also, the twist band design truly highlights the shape and makes a real standout of it. I can't wait to see it with the matching diamond set wedding ring!
1 x 18ct white gold custom designed engagement ring. Set with 1 x 1.30ct F SI2 Trilliant Cut Diamond GIA certified and 0.19ct of round brilliant cut diamonds (E/F VS). Metal Weight 4.60g.
Emily's pick of the month
Rose Gold is a hot fashion trend right now. The colour is achieved by adding copper alloy to the gold mix. It looks particularly stunning with pink diamonds and white, white sparkly diamonds. Ideal for those with pale skin tones such as blondes and redheads - unfortunately does not suit me at all, but I still admire a well designed rose gold ring. This one would be perfect as a wedding or stacker ring.
1 x 18ct rose gold ladies ring. Set with 20 round brilliant cut diamonds of E/F colour, VS clarity in full rub-over settings. TDW 0.30ct.

An unlikely use for diamonds
Tiny diamonds are providing scientists with new possibilities for accurate measurements of processes inside living cells with potential to improve drug delivery and cancer therapeutics.
Published in Nature Nanotechnology, researchers from Cardiff University have unveiled a new method for viewing nanodiamonds inside human living cells for purposes of biomedical research.
Nanodiamonds are very small particles (a thousand times smaller than human hair) and because of their low toxicity they can be used as a carrier to transport drugs inside cells. They also show huge promise as an alternative to the organic fluorophores usually used by scientists to visualise processes inside cells and tissues.
A major limitation of organic fluorophores is that they have the tendency to degrade and bleach over time under light illumination. This makes it difficult to use them for accurate measurements of cellular processes. Moreover, the bleaching and chemical degradation can often be toxic and significantly perturb or even kill cells.
There is a growing consensus among scientists that nanodiamonds are one of the best inorganic material alternatives for use in biomedical research, because of their compatibility with human cells, and due to their stable structural and chemical properties.
Previous attempts by other research teams to visualise nanodiamonds under powerful light microscopes have run into the obstacle that the diamond material per se is transparent to visible light. Locating the nanodiamonds under a microscope had relied on tiny defects in the crystal lattice, which fluoresce under light illumination.
Production of the defects proved both costly and difficult to realise in a controlled way. Furthermore, the fluorescence light emitted by these defects, and in turn the image gleaned from the microscopic exploration of these flawed nanodiamonds, is sometimes also unstable.
In their latest paper, researchers from Cardiff Universityís Schools of Biosciences and Physics showed that non-fluorescing nanodiamonds (diamonds without defects) can be imaged optically and far more stably via the interaction between the illuminating light and the vibrating chemical bonds in the diamond lattice structure which results in scattered light at a different colour.
The paper describes how two laser beams beating at a specific frequency are used to drive chemical bonds to vibrate in sync. One of these beams is then used to probe this vibration and generate a light, called coherent anti-Stokes Raman scattering (CARS).
By focusing these laser beams onto the nanodiamond, a high-resolution CARS image is generated. Using an in-house built microscope, the research team was able to measure the intensity of the CARS light on a series of single nanodiamonds of different sizes.
The nanodiamond size was accurately measured by means of electron microscopy and other quantitative optical contrast methods developed within the researcherís lab. In this way, they were able to quantify the relationship between the CARS light intensity and the nanoparticle size.
Consequently, the calibrated CARS signal enabled the team to analyse the size and number of nanodiamonds that had been delivered into living cells, with a level of accuracy hitherto not achieved by other methods.
Professor Paola Borri from the School of Biosciences, who led the study, said: "This new imaging modality opens the exciting prospect of following complex cellular trafficking pathways quantitatively with important applications in drug delivery. The next step for us will be to push the technique to detect nanodiamonds of even smaller sizes than what we have shown so far and to demonstrate a specific application in drug delivery."

101-Carat Diamond Sells for Nearly $5 Million at Christie's
After record breaking auction prices in recent years for fancy coloured diamonds, it appears that colourless diamonds are now nudging their way back into the spotlight. Seven of the top 10 lots at Christie's Important Jewels auction held Wednesday, featured colourless diamonds with five of the items selling for more than $1 million (including commission and fees).
The top lot in the sale was a 101.36 carat, cushion-cut, L colour, VS2 diamond that sold for $4.98 million, or $49,100 per carat. The diamond, worn as a necklace, is suspended by a black silk cord with pave-set diamonds mounted in platinum (picture below).
All totalled, the sale of 347 lots fetched $33.7million, with 75 per cent sold by lot and 77 per cent sold by value.
"Fine quality colorless diamonds achieved strong prices with international bidding," said Rahul Kadakia, International Head of Christie's Jewelry. "Collectors also bid competitively for natural pearls and special jewelled objects such as the Art Deco fish bowl clock, by Black, Starr, and Frost, which realised $137,000 against a pre-sale estimate of $15,000."
