Bookmatched slabs are supplied in matched Block A and Block B pairs — each pair cut and finished to mirror each other, so when installed side by side they create a continuous butterfly-pattern effect across the veining. The technique is standard in high-end natural stone installations and now available in premium Italian porcelain at 1500 x 3000mm — the largest format bookmatched porcelain currently made. Our range covers the classic marbles reproduced in porcelain — Calacatta, Carrara, Statuario, Onyx and Marquina — with the veining book-matched across paired slabs to produce continuous walls, fireplace surrounds, kitchen islands and reception hall installations that read as single sculptural surfaces rather than tiled ones. Ranges from Ariostea (Ultra Marmi, Ultra Onici), Fiandre (Maximum) and other leading Italian manufacturers. If you can't find the exact colour or finish you're looking for, please get in touch. We have access to one of the UK's largest stocks of premium Italian porcelain slabs, including many additional bookmatched designs available for fast nationwide delivery that are not yet shown online. Both blocks are ordered separately to make a matched pair. Blocks are supplied rectified. Each slab is held in UK stock, ready for immediate delivery in 4-6 working days by specialist carrier.
