Cloisonné lapel pins use an ancient metalworking technique developed in the Far East. The multi-step process, which remains relatively unchanged today, results in a jewelry-like finish whose durability far exceeds that of other processes for your lapel pins. For this reason, Cloisonné is the preferred method for collector’s pins. As you will see demonstrated in the images here, the colors are of a very rich, finite palette unique to this process.
