This vintage sterling vermeil brooch is marked on the reverse with the Uncas logo used from 1919 to 1988. Uncas was founded by Vincent Sorrentino in 1911 and is still in business. This brooch consists of a single flower with multicolored prong set rhinestones. It is in excellent vintage condition and dates to the 1940's when vermeil was quite popular. The closure is a safety roll over clasp with a slight bent to the pin stem. Size is 1 1/2 inches in width by 3 1/4 inches in length.
