Natural pearl and diamond necklace

Composed of 59 natural pearls measuring approximately 12.20 to 6.30 mm., the clasp set with a marquise-shaped diamond weighing approximately 1.90 carats, mounted in platinum, length 22½ inches.

Good condition. The round to near round, white to slightly cream-colored pearls present varying degrees of pink, green and purple overtones, a predominantly satin-like luster with some high luster and waxy examples. Minor blemishing with generally very nice skins. Approximately 7 examples bear minor surface cracking and/or peeling. Pearl #29 from the female end of the clasp reveals what could be mistaken for an exposed bead at the drill hole, but is simply a layer of pearl with lesser orient. The antique marquise-cut diamond is approximately G-H color, VS clarity. The string is knotted, but is stretched and soiled and should be restrung in the future.
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.
