Brooches have a rich history dating back to the bronze age with images of birds and other animals emerging during the medieval era. Art nouveau breathed new life into the art form with a dragonfly brooch stealing the show at the Paris Universal Exhibition in 1900. Each piece features an intricate rainbow array of our Ultimate Diamond Alternative DiamondAura in hammered yellow gold-finished settings. A breakthrough in lab-created gems DiamondAura possesses color cut and clarity to rival the finest mined diamonds and is hard enough to cut glass. The result is that these stone-packed brooches look and feel expensive while saving you a pretty penny.
