Onyx tiles with a difference! 3D Shadow is an innovative collection of onyx effect porcelain tiles which includes a variety of incredibly realistic reproductions of popular onyx stones ranging from cool White Jade to rich River Onyx. The latest 3D digital printing technology gives these onyx tiles stunning depth and detail and the extra-large 180x60cm and 90x90cm formats further enhance the illusion of large slabs of natural onyx. Onyx effect porcelain tiles measure only 5.5mm in thickness but are nearly twice as strong as a standard porcelain tile and can even be used outside, making these beautiful onyx tiles the perfect durable and cost effective alternative to natural onyx tiles.
