Look at this gorgeous brooch, enameled in blues and greens and the stones in his tail are bezel set with red tourmaline. The backing is gilt filigree. 2" wide and 1 3/8 tall. He is a proud peacock with his comb tall and his two red eyes. The stones in his tail tested as tourmaline on my Presidium gem tester. Tourmaline is considered to be the most versatile gem, as it comes in most colors. The gem is a combination of minerals and the amount of each mineral present determines the color. Marked on the back with (a guess) L763. Excellent vintage condition.
