That green mark isn’t “silver reacting to your skin”—it’s almost always copper.
No—properly made sterling silver does not turn your skin green. When discoloration happens, it’s typically exposed copper in the alloy reacting with moisture, sweat, or acidic skin chemistry—most often because of poor alloy control, thin/low-grade plating that’s worn through, or unfinished contact points that leave copper sitting against skin.
