Fancy Intense Green Diamond and Diamond Ring, 5.62 carats (lot 607)

Estimate: HK$22,000,000 – 26,000,000

The occurrence of natural green diamonds are so rare, that very few examples were documented throughout history; and while most diamonds that were discovered with a pure green hue barely exceed 2 carats and often have lower clarity grading, this cushion-shaped Fancy Intense Green Diamond weighs close to 6 carats and has a VS clarity, which is why it is a truly exceptional jewel worthy of any gem connoisseur’s acclaim.

Patek Philippe worldtime wristwatch with two crowns from 1953 (lot 908)

Estimate: HK$10,000,000 – 20,000,000

Made for the rising “jet-set” in 1953, this yellow gold worldtime wristwatch (ref. 2523) is one of the two only known two crowns Patek Philippe to feature a gilded engine turned dial. Not only is it extremely rare to ever see it on the market, it is also remarkable that this one comes with a case that has never been polished, making it one of the best-preserved examples to appear in recent memory.

The two-crown feature was ahead of their time, and the oversized, 36mm diameter was also deemed excessive back then. Though it did not achieve tremendous success when it was launched in 1953, it is now recognised for its pioneering, perfectly balanced design that represents a historic moment in watchmaking history that was ushered in by the jet age.

Burmese royal blue sapphire and diamond ring and pendent earrings (lot 597 and 598)

Estimate: HK$2,300,000 – 3,000,000 (ring) and HK$1,900,000 – 2,400,000 (earrings)

The Burmese sapphire is set apart for its crisp transparency and robust brilliance, but modern mines in Burma yield very few sapphires, and very few fine examples over 10 carats make their way to the present day market. This ring, however, contains a stunning 13.62 carats cushion-shaped Burmese sapphire, adorned with eight baguette diamonds weighing a total of approximately 1.50 carats. The earrings, meanwhile, are also set with two oval Burmese sapphires — weighing 11 and 10.03 carats — along with a total of 3.60 carats brilliant-cut diamonds in the surmount. There are also no indications of heating found in these precious gems, which makes it an exceptionally rare collection to acquire.

Diamond-set Millenary Tourbillon Onyx watch by Audemars Piguet (lot 915)

Estimate: HK$1,200,000 – 2,400,000

Both a jewellery piece and mechanical marvel, this diamond-set Millenary Tourbillon Onyx watch by Audemars Piguet (ref. 26381OR) features a bold look with its 45mm pink gold case set with approximately 11 carats of diamonds, onyx along with a skeletonized tourbillon movement.

Not only is it in excellent condition, this particular piece is also complete with an in-house warranty dated 3 March 2014, service paper dated 9 February 2017, instruction manual, additional extra strap as well as fitted presentation box and outer packaging.

An Art deco diamond and sapphire bracelet by Cartier and diamond double-clip brooch by Cartier London (lot 591 and lot 592)

Estimate: HK$680,000 – 880,000 (bracelet) and HK$120,000 – 160,000 (brooch)

This diamond and sapphire platinum bracelet (circa 1925) contains 38 marquise diamonds weighing a total of 16 carats, 4.70 carats of brilliant-cut diamonds, as well as calibrè-cut sapphires set on the links and central panel. You can see the fine workmanship just by observing the links that is each set with a series of marquise-shaped diamonds, which allows the piece to bend with a softness that matches the elegance of an Art Deco jewel.

The diamond double-clip brooch (circa 1930), on the other hand, is set with approximately 5.10 carats of diamonds, and shares a similar style to the single clip brooch that was once owned by Margaret Thatcher and sold at a charity auction in 2017.

White gold and diamond-set lady's chronograph wristwatch made for the 175th anniversary of Patek Philippe (lot 901)

Estimate: HK$400,000 – 560,000

Manufactured in 2014 for the 175th anniversary of Patek Philippe, this spectacular lady’s chronograph wristwatch (ref. 4675G) is a wonderful blend of complicated horology and jewellery. It was made in a limited number of 150 pieces, and features a multiple scale comprising a tachometer, pulsation scale and telemeter ring, as well as an engraving that reads Patek Philippe Geneve 175th Anniversaire 1839-2014 on the case back. This particular one is also in original condition, and is complete with an original Patek Philippe 175 presentation box, envelop with certificate of origin, and memorial coin, which is rarely seen at auction and will make a wonderful edition to any collection.

Gold, black onyx, coral and diamond-set Patek Philippe lady’s bracelet watch with matching ring and earrings from 1976 (lot 829)

Estimate: HK$270,000-400,000

This lot is a rare and unusual jewellery suite featuring a lady’s Patek Philippe timepiece (ref. 4321-1), accompanied by matching earrings and a ring. Produced 1976 and 1978, each piece displays a strong characteristic of individualism, and is made in 18k yellow gold with a twist rope design, topped with a bracelet comprising teardrop-shaped coral and pave-set diamond in an approximate weigh of 6 carats.

Jadeite cabochon, yellow diamond and diamond demi-parure
(lot 610)

Estimate: HK$160,000 – 200,000

Jadeite, as a gemstone for jewellery, has a longstanding history in Chinese culture. While most people may associate jadeites to passé designs, this demi-parure offers a refreshing look by bringing in a touch of yellow, as well as a subtle scintillation of rose-cut diamonds.
