Very nice earrings, however I wish they were more clear on which diameter they are referring to. I've ordered hoops from another company and always got 8mm (inside diameter). So I ordered the 8mm from this company, and it turns out the are measuring the full diameter of the earring (outside diameter), meaning these are about a 6mm inside diameter - much too small to use in my cartilage. (Unless I completely missed the clarification somewhere on the listing.) But other than clarity on the diameter, these earrings are very nice like the ones I usually purchase and keep in for years at a time.
