Vintage Easter Chicken Egg Long Drop Earrings Possibly Lunch at the Ritz

I think these are by Lunch at the Ritz as they look very similar. However, they don’t have the same thickness of enamel and they have glitter. My grandma got them in the 80s/90s and doesn’t remember where from. Please inspect the pictures carefully as these are vintage and used. I’ve included some close-ups so you can see the enamel/finish better.
