Lovely pin and earrings - minty condition - fabulous color. All pieces are stamped AHS from the same company. 92.5 Mexico. Yes it is a marriage but a good one - the colors are exactly the same. The earrings are screw back. They measure 1 inch long. The pin is a regular bar pin with a roll over clasp. It measures 1 3/8" wide and 1 5/8 inches long. The entire set weighs 21.7 grams if that matters to you. My best guess age wise is 1940 - 1950's. Beautiful set.
