This is the most desired riven slate in the market and we’ve got it! Direct from our suppliers in China, it is very consistent ensuring a smooth, sleek finish. These black slate tiles offer a sophisticated option that suits both modern and traditional dwellings. Unlike our competitors, we do not sell tiles that have great variations in thickness, our thickness consistently ranges between 8-15 mm, whereas others will vary between 6-20 mm – which will leave you with an uneven finish and disjointed look.
