This simple earring by Kristin Perry is a nice way to dress up the curve of your ear (what, you never thought that cartilage needed a bit of flash?).
It’s a very reasonable USD $28, and is made of rhinestones set into gold plated base metal. My only quibble is how poorly the stones seem to be set; when enlarged, it seems you can see gaps between the crystals and the setting. But for the price … eh.
Note that this is meant to be worn in the left ear only; there is no matching earring for the other ear.
