Vintage Lisner Costume Orange and Gold(ish) Clip on Earrings Circa 1955 to 1970

These 'looked old' but I realize that doesn't necessarily always mean something is.

This was my first 'Lisner' find though. The color of the faux stone/glass in the earring is orange and the surrounding part has a dark goldish hue.

The only question I would have is any idea of what decade?

I put max age range at 1970 as due to her advancing age among other things, she stopped buying most costume jewelry and my Grandfather gave her a handful of fine jewelry items from 1970 to 1980.
