Sterling Turquoise Bracelet Earrings Set Mosaic Heart Leaves Mexican ?

Amazing vintage sterling silver and turquoise bracelet and earrings set. Beautiful heart shaped leaves composed of turquoise mosaic in silver. Thick and sturdy set, and definitely vintage. All three pieces are marked sterling. They have a Mexican silver look to me, but Im not sure. Bracelet has a concealed hook closure and earrings have screw-down backings. -- Bracelet measures 7" long and earrings are 3/4" high. All leaves measure 7/8" wide. -- Beautiful vintage condition -- the only issue is some moderate to heavy tarnish. Just gorgeous.
