Pierre Lang XXL Openwork Bow Brooch

Runway-scale statement brooches like this are rarely made today, and this one is stamped with the authentic "PL" hallmark on the reverse to confirm it's genuine Pierre Lang, the renowned Vienna design house. The asymmetrical bow silhouette is worked in airy openwork, with fluid Art Nouveau-inspired filigree cutouts running throughout. It's cast in a heavy jewelry alloy and electroplated in 80-carat equivalent yellow gold, giving it the mirror-polished, high-luster finish the brand is known for.
