caulk/silicone for waterfall

I need opinions on a silicone or caulk that will withstand water submersion without peeling. My masonry guy built a waterfall on our spa spillway out of flagstone; one flat piece for the water to run off & two vertical sides. I would like to caulk the seams between the side walls and flat base piece. Any suggestions? The flagstone is gray, so I would want a colored gray caulk. Thanks in advance!
