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. Gemological Certificates and Reports: References in the catalogue descriptions to certificates or reports issued by gemological laboratories are provided only for the information of bidders, and Sotheby's does not guarantee and accepts no responsibility for the accuracy, terms or information contained in such certificates or reports. Please also note that laboratories may differ in their assessment of a gemstone (including its origin and presence, type and extent of treatments) and their certificates or reports may contain different results.NOTWITHSTANDING THIS REPORT OR ANY DISCUSSIONS CONCERNING CONDITION OF A LOT, ALL LOTS ARE OFFERED AND SOLD "AS IS" IN ACCORDANCE WITH THE CONDITIONS OF SALE PRINTED IN THE CATALOGUE.

附美國GIA證書，編號2175733898，指出鑽石為D色，VS1淨度。附一份GIA信函，指出此鑽石屬 Type IIa。

裝飾藝術設計是張狂形體與內斂蘊藉的平衡。其時的寶石，無論在魯爾曼的櫃中，還是喬治·傑森的調酒器，抑或在克里斯勒的大樓中覓得，均保持這種平衡，線條克制，用色內斂。二十及三十年代，珠寶商運用方形寶石詮釋此美學，包括現在的經典方形及長形切割，有時更用於彩色寶石之上。

此枚戒指，正因簡單，更顯出色驚人。此顆方形鑽石，兩旁鑲直排藍寶石，觀者視線莫不受其吸引。鑽石外表潔白無瑕，或因內裡全不含氮元素，達標者即為最珍稀的Type IIa。世上最著名的鑽石，均為Type IIa，當中「光之山」可謂最著名典例，它在數世紀前被發現於傳奇的戈爾康達礦山（Golconda）。
