The opal on this is so pretty! The only downside is that the piercing is so tiny that in order to get the ball out (by pulling) you have to get a REALLY good(and awkward) grip with your fingers. And then, in order to set the ball back you have to get it in place JUST right otherwise it falls out. It'll just take some practice and a steady hand, but all in all, I love it!

*UPDATE*
I somehow have lost the ball somewhere along the way and it's so tiny that it'll more than likely be lost forever. I'm guessing something brushed against it in my sleep but I am a tad disappointed.  Now I'll have to buy another.
