This double clip brooch by Mazer Brothers features sparkly round and baguette diamanté in a late-Art Deco design. What’s interesting about this piece is that the patent for the brooch mechanism that connects the dress clips was issued to Marcel Boucher in 1939, two years after he started his own company. He filed the patent application when he was working for Mazer Brothers, but the patent wasn’t assigned to them when it was issued. (You can see the utility patent here, below Boucher's name.) I was surprised to find the “MAZER” mark on this piece from the technical perspective but certainly not from an aesthetic point of view. Because this jewel was created with the Boucher mechanism, I think it was made while he still worked for the firm. Wear this lovely piece as a brooch or as separate dress clips.
