Vintage Sterling Silver 925 Earrings -Tourmaline?

Vintage Sterling Silver Earrings. Stamped 925. These are beautiful and I feel they have some weight / substance to them. The bottom moves because it’s on a hinge. I was told these were tourmaline when I purchased but I can’t guarantee since I never had them tested. They show normal wear as they are Vintage. Either way they are beautiful Vintage earrings. They need to be cleaned up and they don’t have the backs. Measurements are approximate and colors may be off because of lighting. Just Reduced.
