Dear Tim:
Two things:
Verde Peacock is too dense a stone (charnockite) to absorb any impregnating/sealer/color-enhancer.
Second, stone is not polished by slapping some sealer on it, but by abrasion and friction, like gemstone.
Charnockite is not the kind of stone that should be installed outdoors and expect that it will remain like brand-new forever. Granite and many other “granites” are suitable; charnockite is not.
The weather will eventually exact its toll and there's nothing that you can technically do about it.
Your best bet is to apply periodically a good-quality paste car wax to your stone.
May I ask you now to please read and e-sign our Statement of Purpose at:

Ciao and good luck,
Mauri
