Art Deco Bi Jade and Enamel Brooch by Carter, Gough & Co.

Striking, to state the obvious, this exotic Art Deco brooch, centering on a glossy green jade donut (or 'bi' in Chinese), is especially dramatic against black fabric. The curvaceous openwork design is artfully colored in green, yellow and black enamel. Crafted in 14K yellow gold, circa 1930, by Carter, Gough & Company. Accompanied by a gemological report from Stone Group Laboratories stating: Natural. No indications of polymers or dyes. Burma origin. We thank Wilson's Estate Jewelry (and from whomever they sourced the information   ;) for the following:

Started in Newark, New Jersey, in 1841 by Aaron Carter, the company changed names as partners came and went. In 1850, the firm was the first to use the power of the steam engine to manufacture its jewelry pieces, such as stickpins, cufflinks, lockets, pins, and coin purses. The company’s founder died in 1902, and his son, William Tuttle Carter, took over the firm. It wasn’t until around 1915 that the official name of Carter, Gough & Co. was used. The design house became one of the largest jewelry producers in the world during its time and often manufactured what was en vogue for the period. Pieces from Carter, Gough & Co. exist in Victorian, Edwardian, Art Deco, and Art Nouveau styles. The firm was also known for its gold enameled work and variety of styles. Although there is not much on record for this design house, collectors still hold their pieces in high regard due to the quality and ability to withstand the test of time while defining an era.
