The plugs are great quality, not sure what the stones are, but I got green, yellow and purple plugs. All of them appear to be great quality and I'm definitely tempted to order the mystery bag again.
I love these I have a daughter on the way so I needed a pair of plugs instead of tunnels so she doesn't grab my ears since they are 22mm and these ones are amazing there a good weight and feel nice in my ears every pair of jewelry I've gotten since I stretched my ears has been from you guys
