Colour and Clarity: According to both AGL and Gübelin reports, the sapphire is natural, of Burma origin, with no indications of heating and clarity enhancement. Please refer to the reports for details. In our opinion, the sapphire is of medium deep, strong blue colour, eye clean. Upon 10x loupe, there are only minor inclusions close to a prong, otherwise quite clean. Two tapered diamonds together weighing approximately 0.40 carat, are about H to I colours, VS clarity. Signed Tiffany & Co. to the shank. Condition: Platinum ring mount, with signs of normal wear, overall in very good condition.
In response to your inquiry, we are pleased to provide you with a general report of the condition of the property described above.

Prospective buyers should inspect each lot to satisfy themselves as to condition and must understand that any statement made by Sotheby's is merely a subjective qualified opinion. Illustrations in the catalogue may not be actual size. Prospective purchasers are reminded that, unless the catalogue description specifically states that a stone is natural, we have assumed that some form of treatment may have been used and that such treatment may not be permanent. Our presale estimates reflect this assumption.
