Brilliant Early Navajo Pendant set with Malachite Chrysocolla in Sterling Silver

Early Navajo sterling silver pendant. It is plain sterling silver with two hand dropped raindrops. The stone is malachite chrysocolla; a beautiful natural mix that has vibrant color. It measures 1 3/8" by 7/8". Very tarnished. No hallmarks. The last photo where the color is light was taken in direct sun.
