Blender Textures Importing to Unity

So say I want to make a gem or window in unity, and i make teh model for it in blender. Is there a way to import the transparency of the texture that i made in blender to unity, and can i do the same with mirror reflections.

Nope. As far as I know, you have to add them in Unity.

EDIT: Unity has some really great gem shaders available here.
