The brooch is supplied with an independent diamond and gemstone grading report card. NOTE: * Plique-à-jour is a vitreous enamelling technique similar in technical execution to cloisonné, where the enamel is applied to defined 'cells' within a metal filigree. With plique-à-jour, there is no backing to the design, allowing light to pass through the enamelwork, suggestive of stained glass. Plique-a-jour is derived from the French 'braid letting in daylight'. Images do not always reflect the true colour and brilliance of gemstones and diamonds. The video however provides a truer representation of the actual colour and showcases each stone. Condition This impressive vintage bug brooch...
