ZS Curve Seven Stud CZ Stud Earrings 316L Stainless Steel Ear Helix Conch Cartilage Piercing

Is the actual stem that goes in ear “ thick “ ? 4 instance currently I have a regular diamond earring in there that fit any of my ear piercings

Are they thick? Would they fit in a normal cartilage piercing?

Are both ends threaded

Is the blue more of a baby blue or aquamarine?
