HIGHLIGHTS:  

DIAMONDS For decades Sotheby’s has had the honour to bring to the market many important coloured diamonds, including the Blue Moon of Josephine that set the world auction record for any diamond last November.  

This Spring Sotheby’s is delighted to offer an extraordinary selection of rare and important top-quality coloured diamonds, led by the celebrated ‘De Beers Millennium Jewel 4’, a 10.10-Carat Oval-shaped Internally Flawless Fancy Vivid Blue Diamond (Est. HK$235 – 280 million / US$30 – 35 million, the largest oval-shaped fancy vivid blue diamond ever to appear at auction.  

  

Another remarkable colour, orange, is in diamonds believed to be caused by nitrogen, the same element responsible for yellow colours in diamonds.  

Only a minute fraction of fancy coloured diamonds are graded as pure orange without modifying hues. 

They are rarely seen on the market, even at the most prestigious auctions.  GIA states that it rarely sees polished orange diamonds exceeding 4 carats.  This 4.08-Carat Fancy Vivid Orange Diamond and Diamond Ring (Est. HK$12 – 14 million / US$1.6 – 1.8 million) from the collection of an Asian lady is a remarkable example of one of the rarest and most prized colour sensations observed in the world of diamonds.  

Its elegant shape is echoed by the similarly-cut adjoining white diamond, accented by a soft curve that continues its subtle outline, freeing the two dazzling diamonds from any kind of enclosure, thus allowing this one-of-a-kind orange diamond to display fully its true marvellous colour.  

While red is by far the rarest hue in fancy coloured diamonds, green comes a close second.  

The green colour in diamonds is caused by millions of years of exposure to natural irradiation in the earth which alters the stone’s absorption of light.  The majority of naturally irradiated diamonds show isolated green strains (also known as ‘skins’) that barely penetrate the surface of the crystal and are almost always removed during the cutting process.  

Only a very small number exposed to radiation long enough exhibit an even green hue throughout the entire crystal.  

Among these rare stones very few have a pure green colour without any bluish, greyish or yellowish modifying hues, making them truly unique, as is the heart-shaped centre stone of this 4.90-Carat Fancy Intense Green Diamond, Coloured Diamond and Diamond Ring (Est. HK$21 – 28 million / US$2.7 – 3.6 million, lot 1842).  

Only a handful of natural green diamonds have been auctioned in the past three decades, the majority exhibited either bluish or yellowish modifying hues.  

With a pleasing heart shape, weighing 4.90 carats (uncommonly large for its kind), this fancy intense green diamond is representative of an extraordinary group of beautiful and enigmatic gems, and presents a rare opportunity for collectors to acquire a peerless stone.  

Pure yellow diamonds with no modifying hues are relatively rare and greatly sought after.  Of significant size, a lively and saturated golden yellow colour and a classic emerald cut, this rare and fine 10.30-Carat Fancy Vivid Yellow Diamond and Diamond Ring (Est. HK$10 – 16 million / US$1.3 – 2.1 million, lot 1846) is certainly a stunner.  

The kaleidoscopic range of coloured diamonds will be complemented by a superb selection of perfect colourless stones embodying the finest attributes in a diamond: D colour, internally flawless clarity, excellent cut, polish and symmetry (Triple X) and the purest Type IIa quality. 

Among them are a 22.40-Carat DIF Diamond Ring (Est. HK$25 – 32 million / US$3.3 – 4.1 million, lot 1844, pictured right) and a pair of 5.03 and 5.02-Carat DIF Diamond Pendent Earrings (Est. HK$7.8 – 8.8 million / US$1 – 1.1 million, lot 1845).  

COLOURED GEMSTONES 

Last October in Hong Kong, a 27.68-carat Kashmir sapphire achieved a world auction record price per carat for Kashmir sapphire at US$242,145 per carat.  

It was the latest in an incredible string of records since the October 2014 sale in Hong Kong in which the same record was broken twice, illustrating the rapidly growing demand for top-quality sapphires.  

This season Sotheby’s is delighted to offer two striking sapphires from different origins, both free from indications of heating and displaying the most captivating naturally saturated blue colour: a 38.88-Carat Burmese Royal Blue Sapphire and Diamond Ring (Est. HK$14 – 16 million / US$1.8 – 2 million, lot 1739, with an impressive size and superior quality, as well as a 12.00-Carat Kashmir Cornflower Blue Sapphire and Diamond Ring (Est.HK$14 – 16 million / US$1.8 – 2 million) with a richly saturated and homogeneous colour and very fine purity which makes this stone highly exceptional.  

Sotheby’s selection of natural coloured gemstones would not be complete without this 6.04- Carat Burmese Ruby and Diamond Ring (Est. HK$18 – 22 million / US$2.3 – 2.8 million, lot 1872), centring on an unheated Burmese ruby of outstanding purity and a beautifully saturated ‘pigeon’s blood’ red colour, which is primarily found in rubies from the famed Mogok Valley, the most prestigious origin for rubies. 

ROYAL JEWEL 

This Colombian Emerald and Diamond Brooch, Late 19th Century, formerly in the Collection of Queen Amelia of Portugal (Emerald totalling approximately 18.60 Carats, Est. HK$9.5 – 12 million / US$1.2 – 1.6 million, lot 1712), is a rare piece originating from the court of Portugal that made its way to Asia through the hands of various illustrious pre- owners.  

Queen Amelia of Portugal was born Princess Amélie of Orléans in 1865.  She married Carlos of Portugal in 1886, who became King Carlos I in 1889.  

Their son Manuel II, the last King of Portugal, reigned until 1910 when the country was declared a Republic.  The brooch was given to Queen Amelia in 1886 as a wedding gift from her godfather, the Duke of Aumale, a son of Louis Philippe, the last King of France.  

It subsequently passed into the collections of the Princes of Orléans and Bragança; HRH, The Crown Princess of Yugoslavia, and the late Gabriele Murdock, wife of the late David Murdock, American businessman and philanthropist.   

The grandeur of this brooch lies not only in its provenance, but also in the three attractive Colombian emeralds that are natural and free of clarity treatment, among which the centre stone weighs a stunning 12.22 carats.  

A noble brooch with such important gemstones is certain to appeal to both antique jewel aficionados and gem connoisseurs. 

SIGNED VINTAGE JEWELLERY With their exquisite designs and craftsmanship combined with scarce supply, well- preserved vintage pieces from renowned jewellery houses are highly sought after at auction.  

The sale offers a charming selection of vintage pieces from celebrated maisons including Cartier and Van Cleef & Arpels which are set to attract jewellery connoisseurs. 

The cover lot of the sale, this Art Deco Burmese Ruby and Diamond Bracelet, Cartier, Paris, Circa 1920 (Est. HK$3.8 – 5.3 million / US$480,000 – 680,000), featuring five natural unheated Burmese rubies totalling approximately 11.00 carats, is a perfect marriage of the finest gemstones, excellent craftsmanship and Cartier’s iconic Art Deco design.  

It is complemented by an Art Deco Gem-set and Diamond Brooch, Van Cleef & Arpels, 1926 and later (Est. HK$800,000 – 950,000 / US$100,000 – 120,000) embellished with carved and cabochon sapphires, rubies and emeralds, which are characteristic of the period’s design motifs.  

Following last season’s Cowdray Pearls that fetched a record price of HK$41.08 million / US$5.3 million at Sotheby’s Hong Kong in October 2015, Sotheby’s is delighted to offer a pair of Natural Pearl and Diamond Pendent Earclips, Cartier Paris, Circa 1949 (Est. HK$6.3 – 7 million / US$810,000 – 900,000, lot 1732), featuring a pair of white and grey natural pearls of similar drop shapes, significant size, and attractive lustre cleverly matched by Cartier and suspended on fan-shaped diamond surmounts. 

Another superb piece featuring natural pearls is a Natural and Diamond Necklace, One Cultured (Est. HK$3 – 5 million / US$390,000 – 650,000, lot 1870) from a distinguished private Asian collector.  

Strung with a meticulous collection of 32 natural saltwater pearls and one cultured pearl measuring approximately 12.50 to 9.15 mm, of well-matched shape, colour and lustre, this exquisite necklace is complemented by a diamond clasp signed by Van Cleef & Arpels. 

    

JADEITE This Exceptional Jadeite Ring (Est. HK$30 – 35 million / US$3.9 – 4.1 million) is an exemplary specimen of superb fine texture, luscious and even green colour as well as captivating translucency – the most highly prized trait in jadeite.  

With a soft glow and gleaming lustre which are remarkably rare for a cabochon of at such an impressive size of 30.08 x 19.23 x 13.07 mm, this top-quality jadeite will captivate discerning jadeite collectors around the world.   

This Fine and Important Jadeite Plaque and Diamond Pendant (Est. HK$28 – 32 million / US$3.6 – 4.1 million) is inscribed with an important sankrit mantra ‘om mani padme hum’ on both sides.  

With deep and diverse meanings, this mantra has been translated into countless languages and is the best-known mantra in the world.  Despite its important size, measuring 68.41 x 36.40 x 8.55 mm, this exceptional jadeite plaque displays a rich and saturated green colour as well as fine translucency and is set to attract collectors with an interest in the Buddhist faith.
