Colour and Clarity: According to AGL report, the alexandrite is natural, of Brazil origin, with no indications of treatment. Please refer to the report for details. In our opinion, the alexandrite shows prominent colour-change effect, from deep blue-green colour in daylight, to deep strong purple colour under incandescent light. Clean to both naked eyes and loupe check. Two diamonds are about G to H colours, VVS to VS clarity. Signed to the shank. Condition: Platinum ring mount, signs of normal wear, 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.
