Funny thing-- I just tried to bump this thread to the top, and for some reason it didn't come up, but here-- you might be able to use this thread linked below.

The only difference is that once you're ready to bullnose the edges, you might want to take them to a stone shop, being that the equipment needed to bullnose granite is a little more expensive:

Here is a link that might be useful: Tile undermount sink

The problem is not bullnosing the granite tile - my tile vendor will do that. nd I'll then do the install/tiling. The problem is concealing the cement board and the plywood UNDER the tile but above the sink.

I found - the lost - a manufacture who make a "rim kit" and that's the name I'm looking for. But thanks for the input.
