Vintage Solid Sterling Silver 925 Gold Tone Pink Sapphire Ruby Earrings

Add a touch of elegance with these stunning pink magenta sapphire gold over sterling earrings. Perfect for any occasion. Makers mark OTC and 925 stamp. I do not have a presidium gem tester, just estimating the stones to be sapphires/rubies based on the hardness of 8 per my diamond tester. Sapphires and rubies are the same thing, they are the same mineral. The stones also fluoresce under blacklight (last photo) confirming they are most likely sapphires or rubies.
