This set of earrings are wonderful.  I bought them for my 8 year old, who was having infection issues with all metal (even titanium) earrings.  These have worked well, and are so very pretty.  The clear ones sparkle exactly like diamonds.  They are very small gems, but that is what we where looking for.  They are perfect, and I am now ordering 2 more sets, as we've given many sets away to her friends that also are having ear piercing infections. They are also kind of flexible, so I find them more conformable to sleep in. I bet they would be great for second or unusually placed piercings.
