RUBY AND DIAMOND RING

Centring on a cushion-shaped sugar loaf cabochon ruby weighing approximately 13.09 carats, surrounded by pear- and marquise-shaped diamonds together weighing approximately 4.90 carats, mounted in 18 karat white and yellow gold.

Colour and Clarity: According to Gübelin and GRS reports, the sugarloaf ruby is natural, of Burmese (Mogkok) origin, with no indication of thermal treatment. Please refer to the reports for details. In our opinion, the ruby is of intense red colour with a touch of cherry tone, slightly included to naked eyes, still lively. Upon 10x loupe, there are natural inclusions and a few surface reaching feathers, not noticeable to naked eyes. Diamonds are about F to G colours, VVS to VS clarity. Condition: Karat gold and white gold mount, in very good condition. IMPORTANT NOTICE: Please note that jadeite and rubies of Burmese origin and articles of jewellery containing jadeite or rubies of Burmese origin all less than 100 years old may not be imported into the US. The purchaser's inability to import any item into the U.S. or any other country as a result of these or other restrictions shall not justify cancellation or rescission of the sale or any delay in payment. Please check with the specialist department if you are uncertain as to whether a lot is subject to these import restrictions, or any other restrictions on importation or exportation.
In response to your inquiry, we are pleased to provide you with a general report of the condition of the property described above. Since we are not professional conservators or restorers, we urge you to consult with a restorer or conservator of your choice who will be better able to provide a detailed, professional report. 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.
