HONG KONG.- Leading Christie's Hong Kong Luxury Week this Autumn, the Magnificent Jewels live auction on 25 November will present The Royal Blue, an exquisite necklace set with 16 extremely rare cushion-shaped Kashmir 'royal blue' sapphires comprising 104.61 carats. With an estimate of HK$100 – 150 million / US$13 – 19 million, it is the most valuable jewel to be offered at auction in Asia this year and a testament to the demand from collectors for rare, coloured gemstones of exceptional quality.

All 16 dazzling sapphires were unearthed in the legendary mines of Kashmir - the undisputed origin of the most desirable sapphires ever discovered. To gemstone collectors and jewellers, the name 'Kashmir', in reference to sapphires, is synonymous with the finest blue colour and the most admired and valuable of all sapphire shades and tones. These 16 mesmerising Kashmir sapphires, which range in weight from 13.37 to 3.43 carats, have all been graded 'royal blue' – one of the most sought-after colour grades for sapphires – and were meticulously assembled to ensure the creation of a true masterpiece. The centre stone alone weighs an astounding 13.37 carats and is an absolute rarity in size. Hailing from an important private collection, the appearance of The Royal Blue at auction marks a significant moment in the history of the jewellery industry, offering a precious opportunity for global collectors to appreciate and own this one-of-a-kind creation.

This breathtaking necklace will be presented alongside a superb selection of over 100 jewels, including gemstones, coloured and colourless diamonds, rare jadeite, and stunning creations from renowned jewellery houses.
