I was looking for a subtle earring that I could wear every day (and night) when I wasn't wearing nicer earrings.  This fits the bill and the diameter sizes are accurate.  I was a little confused by all of the reviews saying the earrings were too small...They are accurately measured, I guess some people just assume the stated size might be a little bigger when they should have gotten a ruler and measured out the diameter they were interested in buying before making the purchase.
