I purchased the DIAMOND 18G Flat Back Push-In Stud - Cartilage, Tragus, Lip, Nose
Color: White Gold
Diamond: 2.0mm, VVS (+$75)
Length: 1/4 in(6.5mm) and absolutely loved it. It was in my ear cartilage as stated on the site as a standard placementofcthis piece. I only had it in for a month when I was washing my hair and noticed it had fallen out. I'm not sure how this could happen if they are made for ear cartilage use. Money literally down the drain.
