I purchased this to wear in my faith piercing.  I had a larger horseshoe earring but it was too big.  I had to go to my piercer to have it put in.  I do wish the bar was just a bit longer.  I don't have big ears; but, this sits so snug that its in my ear a bit too much.  You cant see it unless I actually turn my head.  Its comfortable & very pretty.  The gems screw on securely.
