These cufflinks are handmade from 14kt yellow gold and set with rectangular Lapiz Lazuli cabochons. They feature the bean-back style that was produced from the mid 1800s - the 1910s. Each cufflink has hand-engraving on the setting around each piece of Lapis Lazuli. The cufflinks are marked with a stamped three petal shamrock containing "14 A". We were unable to attribute these cufflinks to a particular country or manufacture, but they test as 14kt gold and we are certain they are antique. Each Lapiz Lazuli cabochon measures 9.5x12mm, the face of each cufflink measures 13.8x15.2mm, the bean-back measures 8x11.5mm, the distance of the bar from front to back is 7mm. The pair weighs 7.4 grams. This pair of cufflinks would be a wonderful addition to any collection!
