Why don't you fake it for yourself?
Go to the craft store and get some
flat-backed gemstones. You find them a lot in the scrapbooking areas, sometimes in areas that have beads. You can get them self-adhering or not. Sizes 3-4mm would be about the size of the end jewelry you'd be wearing in it anyway.
Get some eyelash glue (I like the kind with a brush wand and not just a tube), apply the glue to the back of the gem, then stick it on your face. Wear it there all day, go out with it on, whatever. See if you like the way it looks on yourself for a few days. If you end up liking the faked gem, you'll probably like the real thing.
Also, you get pierced for yourself, not because other people think it'll be pretty on you. Do it because you want it. If you want outside opinions, at least get them from people you trust most, from people whose opinions matter. Not random strangers on the internet trying to judge based on a photograph.
