After debating Silestone vs soapstone, it came down to money - which we don't have much of at this point - and resale potential.
Hubs and I both love soapstone, and will probably install it in our "forever" house (if there is such a thing). It's old. It's gorgeous. It ages naturally. It is quite common in Europe.
Silestone, on the other hand, looks more like granite. It's been featured in all kinds of home decor magazines, as well as the street of dreams. It has no VOC emissions and offers consumers the joy of preparing food on a antimicrobial surface (sort of freaks me out but whatever). It's also one of those counter tops that is more appealing to the masses.
And the real kicker - the Silestone, thanks to two promotions running simultaneously, is MUCH more affordable.
