These are lovely little earrings with a lot of sparkle.  They're very eye-catching in direct sunlight.  They seem to be quite a beautiful princess cut, though to be honest the earrings are so tiny that I can't see as much detail as I'd like.

Because of their size, I'd recommend these to someone with multiple ear piercings, as accent earrings that will catch the eye and yet not draw attention away from the main earrings.  They'd catch the light very well at a theatre or a museum, somewhere where there are many bright lights.  As primary or solitary earrings for an adult, I think they're a bit small.  I've uploaded photos that show the size of the earrings in an adult ear.  They'd also work for a child, if that child requires gold because of sensitivity to other metals (and if the child can be trusted with real diamonds!)

7/2/12 update: As another reviewer has pointed out, these earrings shipped with no gift box.  They shipped flat in a thin box which would normally be used for a CD or DVD, and the ones I received were both bent as a result.  (*~ Sunshine ~* has uploaded a photo of the packaging.)  We both received these earrings through the Amazon Vine program, so packaging may be different for a regular purchase.  The description claims "Package: Regal Blue Sueded-Cloth Box", but I can't seem to confirm that with Amazon.  It might not be a bad idea to check with Amazon before buying these earrings.
