The scroll work on the sides is probably done in royal icing on top of the fondant.
I posted about something similar last month, and someone suggested punching out gelatin sheets and adhering the punched circles with a drop of clear piping gel, with another little bead of gel on top of the circle. Here is a link to that thread, I hope:

I haven't a clue about the sparkly crystals.
It looks to me like the scroll work is done with clear piping gel.
You can buy edible pearls in several sizes and several colors for a reasonable price from: http://www.confectioneryhouse.com/product.php?productid=3414&cat=307&page=1
I have made my own glitter gel by mixing hologram dust with piping gel. See this cake: http://www.cakecentral.com/modules.php?name=gallery&file=displayimage&pid=102133
Leah - Where do you get your glitter gel?
It's a new BakeryCrafts product. They wholesale only, but surely someone besides sugarcraft.com sells it retail. It comes in a 5 # bucket, and i thought that would be a lifetime supply, but I'm finding all kinds of ways to use it. it also takes color well. I used it yesterday for water on a groom's cake. The water shimmered with the glitter gel.
BakeryCrafts has also introduced three new glazes. it's basically a thin edible paint. They have silver (I don't recommend it) and gold (highly recommended) and pearl (very good.)
Thank you, Leah. I found the glitter gel here http://www.pastrysampler.com/Coloring.htm I've never ordered from this company before, but it looks like a good resource - especially if you're into Ateco products! 
do any of you think that coating an entire cake in a thin layer of piping gel would be too nasty???? I mean, the stuff doesn't taste good does it?? I ask because I have to make a cake that looks like an ice cube or a block of ice and I'm planning to cover in white fondant and then airbrush pearl dust or something on it.....but piping gel over the entire thing would probably give it a super realistic icy look but do you think that would be disgusting to eat???

You'd only need such a thin coat, that I wouldn't worry about the taste. However, I'd use confectioners glaze to get a sheen. It smells pretty nasty right out of the bottle, but it dries with no odor or taste. I use it whenever I need something to shine.
Actually, now that I think about it, you may not need anything more than a little water. If you lightly moisten the fondant with a paintbrush , it will shine. And the shine doesn't go away even after the cake dries. Try it on a sample piece of fondant and see if it works!
if you take a look at my "ocean wonders" cake you can see the fondant painted with water - the orange fish, coral and grass is painted with water...
hope you find something that suits it!
