Vintage / Antique I. Michelson Art Deco BroochIt is signed in a cartouche on the back - an M superimposed on a C, and the words 1/20 12K GOLD FILLED - which is an early mark. The company was in NY, NY and was in business from 1884 until 1931. Beautiful design. The rhinestones in this period were considered Ruby Red..however as you can see in photos that it does have almost a firey orange red look to it. This piece does need a good cleaning. Especially one of the leaves. The stones look to be original from the piece..however over time there is no telling if the pin closure has been replaced or repaired.Pre-owned and used. Shows wear. A little over 2.5" in size.
