All our slabs arrive pre-resined and polished direct from Brazil to our RIOSTONES yard and showroom so they are all ready for cutting according to the template you require.

At RIOSTONES we make a point of treating all our clients as if you were our very first customer. We know that it can be difficult at times to finally decide on any particular color and pattern of natural stone slab when there are so many beautiful and unique samples to choose from.

We will do everything we can to help you to narrow down your choice by answering all your questions honestly and openly, and will explain all we know about the most appropriate uses for each type of natural or prefabricated stone.

We will also show you samples of the different depths of slabs, types of edgings and joints so that you can make the decision how best to finish your specific project, depending on the look you want to achieve.
