Yeah to get best results you will want to bake it if you are going to play with pearls. You can probably get pearls in acrylics and do it at home, I'm not too sure.
The OEM captiva blue has a silver pearl in it, and I got that in Acrylic, so maybe you can, but it wouldn't be as good as you think, and if you haven't tryed it before, I wouldn't be trying to paint pearl straight away, it consists of different mixing ratios that I'm not too fond of.
