Love these rings! I also have the Peridot version. They don't tarnish or leave blue marks like cheap jewelry might, and the stones stay bright and beautiful. The moving part is a bit loose and the setting is tall, so I worry a bit about snagging it and pulling it off, but it seems well made enough to just be careful not to wear when I'm doing lots of manual labor. Overall totally worth it to help ease the cuticle picking!
