Pretty easy! I'm using a small glass plate I found at a thrift store years ago and a ring-tailed lemur figurine.
I chose a matte spray paint suited for use on plastics, but you can really use whatever you like.
The easiest way to do this is to apply the glue to the bottom of the figure, let sit for 30 seconds or so, and then press it lightly down on the plate in the right place.
If your figurine can't stand on it's on, you'll have to do some creative balancing because the weight of the figure will allow the glue to set properly.
Place the plate + figure in a safe, clean place where it can't be disturbed for at least overnight. E6000 can take a very long time to cure (24 hours), so it's better to be safe than sorry!
If you're using spray paint, I recommend several light coats. It'll look nicer!
This is especially important if you're using a soft plastic figurine - sometimes their colors bleed when you start painting.
You may want to apply a clear coat after if your jewelry stand gets a lot of love! Otherwise just let it dry overnight and then use it.
