This life-sized dragonfly pin is a bold statement for any outfit. This Art Nouveau style pin is finely crafted in 14 karat yellow, consisting of life-like varying colors of yellow, and blue enamel wings, diamond pave body, with large blue cabochon sapphires depicting the dragonfly eyes. Bringing even more life-like quality to this pin is the technique of "En Tremblant" wings - a French term – meaning “to tremble”. It was first used to describe 18th and 19th-century jewelry where parts of the diamond set pieces were attached to a trembler (a material that acts as a spring such as a thin metal wire) to create movement in the jewel when worn.
Shreve, Crump & Low Gemologist Notes: Plique-à-jour (French for "letting in daylight") is a vitreous enameling technique where the enamel is applied in cells, but with no backing in the final product, so light can shine through the transparent or translucent enamel. It is in effect a miniature version of stained-glass. This hand-crafted method is considered very challenging technically: high time consumption (up to 4 months per item), with a high failure rate.
