Caulk on quartzite?

J B
last month

The grout between the backsplash and countertop behind my sink has crumbled. I was thinking of scraping what is left out and filling in with silicone caulk. The quartzite is porous- Mount Blanc, around the rim of the sink there are some water stains. If I seal the backsplash with silicone caulk, do I need to be concerned with something in the caulk staining the quartzite?
