Sotheby's, one of the oldest auction houses in the world, is a global company that engages in art auction, private sales and art-related financing activities. In an exhibition held at the Taj Mahal Palace and Towers, Mumbai, pieces of art and fine jewellery to be auctioned later at New York and London were displayed.

The Chinese contemporary art pieces which are scheduled to be sold in New York included works like Bloodline series no 8 by Zhang Xiaogang, Mao by Yan Pei-Ming and Great Criticism Series:Cartier by Wang Guangyi.

"It's potentially flawless," claimed Lisa Hubbard, Chairman of International Jewellery Division at Sotheby's North and South America Division, when she showed us this piece. The reason: the original working diagrams stating that the stone may be potentially flawless will accompany the piece.

The main diamond is an emerald-cut diamond weighing about 24.42 carats and is surrounded by tapering baguette diamonds. This completely colourless stud of a diamond falls in the type 11 category. Type 11a stones are mostly chemically pure and are often colourless, whereas the type 11b stones are blue in colour. The type 11a diamonds originated in the Golconda region in India, and some great diamonds like the Kohinoor, the Regent and the Great Mogul are all classified as type 11a.

The pieces from this French jewellery house are truly breathtaking. Just like most of their sophisticated designs this necklace too captures the tradition meets contemporary style. This flexible foliate motif set with 159 pear-shaped diamonds and 93 baguette diamonds weigh about 103 carats.

The diamonds are set in platinum once again. The necklace can also be detached – the side segment forming a bracelet of seven and a half inches. They come in a signed box.
