Authenticity & Testing

The value of an antique jewel is not simply the sum of its composite materials; rather it is dependent on its rarity, uniqueness, provenance and the quality of its design and construction.

Accurately dating antique jewelry is a complex process that relies upon a combination of testing, observation and historic research. Wanton has a GIA (Gemological Institute of America) certified gemologist examine our antique pieces utilizing the established practices of the Gemological Institute of America. Please note that in order to protect and preserve the integrity of the antique settings, colors, weight and clarity grades are established in mounted pieces and are therefore determined approximate. Actual weights, colors and clarity grades may vary if stones are removed from their mountings. With the exception of pieces certified by GIA, all grades are to be considered estimates. Please note that throughout various eras, colored stones, pearls and other gemstones may have been treated to enhance color, stability and or clarity. Such enhancements are not always detectable. Thus unless otherwise noted, items may be enhanced.

Dating antique and period jewelry is a complex process, as periods and styles often overlapped, with avant-garde designers introducing stylistic innovations and advances in construction years ahead of the crowd. Approximate dating is achieved by carefully examining and analyzing the materials, construction, condition and aesthetics of a piece in conjunction with the history of aesthetics, design, fashion, and jewelry history utilizing our extensive jewelry library and our research expertise in these areas.
