I am delighted to have acquired an early MATL dove brooch. The stones are turquoise color, probably dyed, as Mexico has little to none. There are two doves with stones and a very pretty arrangement of turquoise colored stones in the center, across the drop and the dangle drops. None missing. The brooch is 2 3/8" wide and 2 5/8" tall. Sturdy safety clasp. Weighs 0.7 ounce. Marked Patente 10466, Mexico, 925. Matl in script. Excellent vintage condition. 1930s.
