This brooch was made in Europe, probably in France since trombone clasps were not used in the States.
Iris glass was created to replicate the natural quartz which washed down from the River Rhone through Gablonz and the Gablonzers created Iris glass to simulate it.
1 1/4" X 3/8"
Very good antique, previously worn condition
