The five peridot gemstones in this vintage brooch represent the stars in the Southern Cross asterism that is part of the Crux Constellation in the southern night sky. They are a fabulous green color and are prong set in gold that is unmarked but tests as 14 karat. The brooch has an early safety catch and we believe it dates from the early 1900's. It measures approximately 2 inches by 1.5 inches and weighs 4.6 grams. Unusual and exceptionally beautiful, the brooch is in excellent condition.
