Vintage Green Mistletoe Clip On Christmas Earrings 1960s 1970s

The only stamp they have is one that says Hong Kong. I am not sure if they are indeed mistletoe, but that is what they remind me of. I don't know much about this other than it was my grandmother's. She was born in 1925, and passed in 2007. I'm 48 now, so I know it's aged well. :)
