VTG Avon necklace/ earrings set, blue pendant pastel stones

Avon necklace, chain is gold tone, earrings matching set with pastel shades. Large blue pendant has yellow mixed in with shade. I am not sure if that is how it was made or if it changed colors over the years. The other stones are one color. I ship the next day whenever possible. I accept all reasonable offers. Thank you for looking.
