This petite but eye catching vintage pin is a perfect example of Mid-century modern style and Guilloché enameling. Guilloché enamel is a technique popularized in the 1880s by Peter Carl Fabergé, best known for his Fabergé eggs, in which a surface is engraved with an intricate repeating pattern and then covered with glass enamel. This 14 karat yellow gold pin is delicately bezel set with one .02 carat old European cut diamond which is perfectly color contrasted by the teal blue and white of the enamel. Ready to be worn vertical, horizontal, or diagonal depending on your outfit styling.
