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. Certificates of Authenticity: Various manufacturers may not issue certificates of authenticity upon request. Sotheby's is not under an obligation to furnish the purchaser with a certificate of authenticity from the manufacturer at any time. Unless the requirements for a rescission of the sale under the Terms of Guarantee are satisfied, the failure of a manufacturer to issue a certificate will not constitute grounds to rescind the sale.
