Metal irritated my ears.
For the price point, I wasn't expecting fine jewelry, but after wearing just a couple weeks, these made my decade-old (and long since fully healed) lobe piercings start oozing and itching.  I have somewhat sensitive ears, but usually don't have a problem even with a lot of the metals that tarnish more quickly.  In addition, most of the silver on these tarnished in that time, and one of the posts is now bent at an angle from the back of the gem.  They were very pretty and true to color, but I don't think they should be worn more than part of a day at a time, and I like to just put studs in and forget about them for weeks to months.
