With colored diamonds being all the rage these past few years, Sotheby’s is set to unveil the Golden Canary in Dubai, UAE today. Weighing 303.10 karats, the deep brownish-yellow gem is one of the largest polished diamonds in the world, and the “largest flawless or internally flawless” diamond ever graded by the Gemological Institute of America.

The historically remarkable gem was once known as the Incomparable Diamond, weighing just over 407 karats. It was then recut from its original shield shape to a classic pear shape, thus making it deeper in color and brighter in hue. The exceptional gem will travel around the world, making stops at Sotheby’s galleries in cities including Taipei, Geneva, Hong Kong, and will also headline its Magnificent Jewels auction in New York on December 7. With bidding starting at just US $1, it is expected to be valued at $15 million, and offered without reserve.

In the UAE, the global unveiling of the Golden Canary will take place alongside the launch of an exhibition featuring rare luxury items which will be available for immediate purchase. Think, wardrobe treasures like Hermès Birkin and Kelly handbags, which have been transformed by luxury brand Jay Ahr, and are making the Middle East debut. Other highlights of the exhibition open to the public till November 4, are Lebanese jewelry designer Gaelle Khouri’s new collection, and striking contemporary photography by Morocco-born artist Lalla Essaydi.
