An Extraordinary 118.88 Carat Burmese Unheated ‘Royal Blue’ Sapphire and Diamond Pendant
Estimate Upon Request

Presented in a blue leather fitted case, this cushion-shaped sapphire is impressive in size and weighs 118.88 carats. Exuding qualities intrinsic to the most exceptional Burmese sapphires, it is accompanied by a report from the Gübelin Gemological Laboratory stating that the sapphire possesses a combination of outstanding characteristics: “It displays a homogenous and richly saturated royal blue colour, which typifies the finest of these gems. The depth of colour, combined with a high clarity and brilliance, all contribute to the beauty of the gem.

Prized by royalty and discerning collectors, Burmese sapphires are renowned for their royal blue colour and enticing lustre. Examples of Burmese sapphires of notable size rarely come to the market. One of the most famous is the Rockefeller Sapphire, a 62.02 carat rectangular step cut stone that was unearthed in Burma, and acquired by financier and philanthropist John D. Rockefeller, Jr from an Indian Maharaja in 1934.


An Exceptional 6.41 Carat Unheated Burmese ‘Pigeon’s Blood’ Ruby and Diamond Ring, Designed and Mounted By FORMS
Est. HK$17,000,000-22,000,000 / US$2,210,000-2,860,000 Michael Oldford

Rich in colour, regal in stature, and steeped in history, the ruby is legendary. For centuries, European royalty have sought some of the world’s most prized rubies to adorn their jewels. From The Sunrise Ruby (sold at Sotheby’s, for a world auction record price for a ruby), to jewels from the Royal Parma Family, rubies are highly esteemed for their mystique and beauty.

Less than 10% of all gem-quality rubies are unheated, making them both rare and impressive. Darker rubies are often heated to enhance their shade, but unheated rubies are naturally intense and vibrant.

This exquisite 6.41 carat natural Burmese ruby is surrounded by French-cut diamonds in a seemingly unassuming setting that amplifies the beauty of the gemstone, in a timeless design by FORMS.

From an important private collection, and a highlight of the top quality colour diamonds on offer in the sale, this captivating pear-shaped 4.84 carat Fancy Vivid Blue Diamond is set in the form of a ring, flanked by two brilliant-cut diamonds each weighing 1.1 carats.

An exquisite and unique pair of Fancy Intense Blue Diamond and Diamond Pendent Earrings (pictured right, est. HK$28,000,000-35,000,000 / US$3,640,000-4,550,000) showcase impeccable craftsmanship through the diamond cutter’s extraordinary skill in retaining such a high level of saturation in the blue diamonds within a brilliant-cut.
