Platinum, Colored Stone and Diamond Brooch, Mauboussin, France

Designed as a jardinière decorated with carved and buff-topped rubies and emeralds, accented by carved sapphires, set with variously-cut diamonds weighing approximately 3.80 carats, signed Mauboussin-France, numbered 1234, with French assay marks; circa 1930.

In good condition with gentle wear and scratching, commensurate with age. Minor areas of gold solder to the mounts of several carved colored stones, possibly from the time of manufacture, and a touch of lead solder to the top carved emerald; seen only under magnification and from the reverse. The medium-deep purplish red rubies, medium blue sapphires (with notable but attractive color zoning) and medium slightly bluish green emeralds are heavily included with surface-reaching inclusions as typically found in carved material. Some of the colored stones are beads, and a diamond has been placed in the drill hole of one fluted emerald bead. The drill holes to the second fluted emerald bead and the single ruby bead are intentionally without diamonds. The diamonds are predominantly G-J color, VS-SI clarity, with the occasional I clarity example. Signature located at the base. Length approximately 2 5/8 inches.
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.
