Guilloché enamel cuff links, now available in purple, $55
Guilloché enamel is a technique popularized by Peter Carl Fabergé, best known for his Fabergé eggs, in the 1880s in which a surface is engraved with an intricate repeating pattern and then covered with glass enamel. This sunburst pattern reflects light through the translucent enamel in different ways depending on the angle.
Guilloché fell out of favor with cuff link makers around the 1950s. To our knowledge, we are the only contemporary producers.
