This is the Fianna Pendant by Ewa Kovács, a wonderfully talented Hungarian beader who graciously offers tons of awesome free patterns on her blog. The site is in both Hungarian and English, but the patterns are only in Hungarian. Luckily, her beautiful full color photos and helpful diagrams make following them easy even if you don’t speak the language. You can get this pattern here: http://ewagyongyosvilaga.blogspot.com/2011/08/fianna-medal-minta-fianna-pendant.html
In case you are wondering, those are indeed Tila beads fanning out from the centers. I love tila beads, so it's probably no surprise that I found this design absolutely enchanting. The pattern wasn't too difficult but does require that you feel comfortable enough to bezel a rivoli with peyote stitch (since there are no instructions for that part). But the rest of the pattern is very straightforward and fairly simple.
