Crystal Pendant and Earrings SET

I made this pendant and earring set for my mom. The crystals are pink, clear, and blue. The square spacers also have crystals, and none are missing. When I made jewelry, I usually bought sterling ear wires, but I cannot see the marking. She wore these for decades without any allergic reactions. They catch the light beautifully and are quite attractive when worn. The condition of all three pieces is excellent! (JEW:C)
