Phillips Presents Jewels and Jadeite Hong Kong Spring Auction Highlights


Featuring A Dazzling Array of Coloured Diamonds and Gemstones, Signed Jewellery and Important Diamonds




Hong Kong – 29 April 2021 – Phillips is pleased to present an extraordinary range of jewellery in its upcoming sale of Jewels and Jadeite in Hong Kong on 5 June at the JW Marriott. Featuring 165 lots, the sale is led by a pair of exceptional Fancy Blue diamond earrings and a stunning Fancy Blue diamond pendant/ ring. A 10.59 carat, Asscher-cut, D-Flawless, Type IIa diamond ring will also grace this season’s auction. Moreover, the sale comprises a wide range of thoughtfully curated diamonds, coloured gemstones, and signed pieces by iconic houses including Harry Winston, Cartier, Van Cleef & Arpels and Graff,among others.


Graeme Thompson, Worldwide Head of Jewellery said: “Following a 100% sell-through rate for jewellery offered in the recent INTERSECT cross-category online auction, which demonstrated a highly resilient market for fine quality jewels in Asia, Phillips is delighted to offer a dazzling and delightful selection of jewellery this spring. This season’s sale marks Phillips’ tenth jewellery sale in Hong Kong, which represents an important milestone as we continue to build a thriving business and expand our presence across Asia. We are particularly proud to be entrusted with an extremely rare 10.59 carat, Asscher-cut, D-Flawless diamond from the Letšeng mine in Lesotho, Southern Africa, a perfectly matched pair of 1.12 and 1.13 carat Fancy Blue diamond earrings and a 2.21 carat Fancy Blue diamond pendant/ ring. I am confident the diverse offering of this collection, from the rarest diamonds to the most sought-after iconic designs, will have vast appeal to international collectors and influential tastemakers alike.”  


D-Flawless Diamonds


This season, Phillips will offer a selection of D-Flawless diamonds of the finest colour, the highest clarity and the best cut and polish, conferred by the GIA. The collection is led by a rare 10.59 carat, Asscher-cut, D-Flawless diamond which has been cut and polished from a 30.80 carat rough diamond from Lesotho’s Letšeng mine, the birthplace of some of the largest and highest quality colourless diamonds in the world. In addition to its colour and clarity grade, the diamond is classified as a “Type IIa” diamond, the most chemically pure type of diamond which displays an exceptional optical transparency. “Type IIa” diamonds are very rare, accounting for fewer than 2% of natural colourless diamonds.



A Pair of 3.05 and 3.13 carat D-Flawless Diamond Ear Studs

Estimate: HK$ 1,100,000 – 2,100,000/ US$140,000 - 380,000


A 10.59 carat D-Flawless Type IIa Diamond Ring

Estimate: HK$ 5,500,000 – 6,500,000/ US$ 700,000 – 850,000


An 8.06 carat D-Flawless Type IIa Diamond Ring

Estimate: HK$3,500,000 – 4,500,000/ US$ 450,000 – 580,000


Coloured Diamonds


Historically, blue diamonds are deemed to be one of the most desirable and sought-after of all jewels, with sizeable blue diamonds weighing over 2.00 carats being incredibly scarce. A matched pair of Fancy Blue diamond earrings and a Fancy Blue diamond ring/ pendant will headline this season’s sale (illustrated page 1). The blue diamonds offered as two lots have been meticulously cut to maximise their inherent and exquisite blue colour, displaying an evenly distributed sky blue. With clarity grades of VVS to VS, these blue diamonds are exceptional, making them highly collectable and coveted jewels.


Also on offer this season is a cushion-shaped Fancy Vivid Yellow diamond ring, with the elegant and classical old cutting style, reminiscent of the finest old mine diamonds. This sizeable diamond over 5.00 carats displays a rich Vivid Yellow colour, often described as “Zimmi”. The name is derived from the Zimmi mines located in Sierra Leone, West Africa, a region that is renowned for producing the world’s finest yellow diamonds. Except its exuberant pure yellow hue, vivid saturation and high clarity grade, the antique cutting style makes this diamond extremely rare and even more desirable.


A Pair of 1.12 and 1.13 carat Fancy Blue Diamond and Diamond Earrings

Estimate: HK$4,000,000 - 6,000,000/ US$500,000 – 780,000

Harry Winston


Signed jewellery from some of the world’s most renowned jewellery houses continue to realise strong prices at auction. Among the signed treasures to be offered this season are several pieces of Harry Winston jewellery. Crowned the ‘King of Diamonds’, Harry Winston was arguably the world’s most celebrated jeweller from the 1950s right through to the 1970s, with clientele that include global royalty, successful business figures and Hollywood stars. One of the most iconic designs of Harry Winston, the “Cluster” (also known as the ‘Wreath’) is an impeccable marriage of the brilliance of diamonds and intricate craftsmanship of the house. This unique design can be seen in one of the leading highlights this season – a beautifully crafted diamond bracelet. The beauty is in the simplicity of the design which sets variously-cut diamonds at different angles with the sole aim of ensuring that each stone captures the light from all directions. Also included is a meticulously-crafted, entwined diamond necklace, showcasing the extreme scintillation of diamonds and creating a three-dimensional jewel with seamless fluidity. 



Harry Winston

A Diamond Necklace (weighing approximately 79.00 carats in total)

Estimate: HK$1,500,000 – 2,000,000/ US$200,000 – 250,000



Harry Winston

A Diamond Winston Cluster Bracelet (weighing approximately 55.00 carats in total)

Estimate: HK$2,000,000 – 3,000,000/ US$ 250,000- 400,000


Coloured Gemstones


This June, Phillips will yet again present the finest Burmese Pigeon’s Blood rubies. Rubies mined from Mogok in Myanmar have become increasingly rare in recent decades and are perennially in strong demand around the world. The present example weighing 4.00 carats, is an unheated circular-shaped Burmese, Pigeon’s Blood ruby with a characteristic vivid, crimson hue, signed by the illustrious House, Cartier.


Kashmir sapphires are some of the most expensive gems in the world. The allure of sapphires from Kashmir partly rests in their legendary origin amidst the Himalayan Mountains, a source that was exhausted over a hundred years ago. Their vibrant blue hue with a rich and lustrous velvety appearance, is often referred to as ‘cornflower’. Any sapphire from Kashmir weighing over 5.00 carats and free from any heat treatment, such as the present oval-shaped, 5.74 carat Kashmir sapphire and diamond ring, is highly desirable and coveted by jewellery connoisseurs.





Cartier, A 4.00 carat Burmese “Pigeon’s Blood” Ruby and Diamond Ring

Estimate: HK$1,600,000 – 2,000,000/ US$200,000 - 300,000


A 5.74 carat Kashmir Sapphire and Diamond Ring

Estimate: HK$2,500,000 -3,500,000/ US$330,000 -450,000



The finest Colombian emeralds exhibit a richly saturated and homogeneous bluish green hue, and often possess a variety of internal inclusions, or fingerprints of nature, due to the delicate balance of their formation and the demanding methods taken to obtain these precious gems. Untreated examples with high clarity are thus extremely rare and sought after. This season, Phillips presents a spectacular 16.47 carat cushion-shaped Colombian emerald and diamond ring, by Van Cleef & Arpels, circa 1965 and a pair of Colombian emerald and diamond earrings by Harry Winston, with both emeralds possessing the exemplary qualities of the finest Colombian gemstones – each free from oil treatment, and with a highly desirable intense colour and a well-proportioned cut.  




Van Cleef & Arpels, A 16.47 carat Colombian Emerald and Diamond Ring

Estimate: HK$2,300,000 - 3,300,000/ US$300,000 - 430,000


Harry Winston, A Pair of 8.61 and 8.01 carat Colombian Emerald and Diamond Earrings

Estimate: HK$4,500,000 - 5,500,000/US$580,000 - 700,000
