It stamps really nicely on vellum. Look here at the punched flower card - very pretty:

It also works as a 'resist' ink - do a search for 'Brilliance resist' and I'm sure you'll find ideas and samples. I use mine a lot - love the shimmer effect and the colors it comes in. I have lots of samples in my gallery using Brilliance, but the pics/photos seldom show the true shimmering results, either using the scanner or camera, sorry.
