Vintage malachite dangle earrings, bezel set in sterling, 1 inch

These are vintage sterling silver and malachite dangle earrings that are one inch with a total drop length of just under one and a half inches. There is paint of some type on the back and a small amount on the side of one. I have not been able to get it off however I do not have any oil paint solvents. The bit on the side is really not visible and very small and the back is general not seen at all.
