Vintage Avon Birthstone Teardrop Pendant Necklace with an imported Austrian Glass Stone in Ruby for the month of July set in goldtone. Introduced in 1976, it is 20 inches with a spring ring clasp and signed '©AVon' hangtag. The chain is a little unusual because on one side of the chain it has 2 larger chain circles for controlling the length using the clasp. Very pretty piece of vintage Avon jewelry even if the ruby is not your birthstone!
