Asia is the primary source of natural rubies and those from the renowned Mogok Valley in Burma remain the most revered in the world. The microscopic curvaceous, angular substances in these rubies disperse light evenly to every facet of the stone, allowing it to glow with an even and intense red hue. Featuring 84 Burmese rubies totalling nearly 140 carats, including a centre stone exceeding 12 carats, this spectacular piece stands as one of the most important unheated ruby necklaces to appear at auction over the past decade in terms of total weight. Part of the rubies are certified the most desirable “pigeon’s blood” colour by the Swiss Gemmological Institute (SSEF) and Lotus Gemology (Lotus). Set with 101.25 carats of diamonds that sparkle like flower petals accentuating the pure and saturated red of the rubies, this necklace promises to be a show-stopper.

With the depletion of the Mogok mine, Mozambican rubies have become increasingly popular among collectors in recent years.

With a characteristic tinge of orange, yellow diamonds from the Zimmi mine in Sierra Leone are richer and more vibrant in their colours than their counterparts from other parts of the world. Completely free of flourescence, these yellow stones possess a unique radiance comparable to daffodils in full bloom. However, black feathery inclusions and holes are commonly found in the rough of these gems, both resulting in huge wastage in the cutting process. Zimmi yellow diamonds exceeding 5 carats are therefore extremely rare. Certified by the Gemological Institute of America (GIA) as of the most desirable fancy vivid colour grading, these 5.02 and 5.01-Carat Natural Fancy Vivid Yellow Excellent Polish and Symmetry Diamonds from Zimmi sparkle with the golden glory synonymous with the legendary mine. Offered in a matching pair, these majestic stones evoke the penetrating eyes of a tiger and are certainly a haunting sight to behold.

Among the various forms of jadeite jewellery, the bead necklace stands as the most sought-after, not only because its creation requires a large supply of rough of homogenous quality, but also because the perfectly round shape of each bead involves meticulous polishing which poses a challenge for the craftsman. Today jadeite bead necklaces of excellent quality have become extremely rare. Strung with 49 jadeite beads of substantial sizes, luxuriant green colour, wonderful translucency and fine texture, this necklace is undoubtedly a superlative example of the grace and virtue traditionally represented by jadeite.
