Hi Elena, the material is 3cm ( Calacatta Vagli ) it comes in different varieties the client a designer and friend in the photo's paid $7,000 per slab used 3 slabs on project, here is one source link: https://ariastonegallery.com/2cm-calacatta-vagli-marble-1.html

I would also highly recommend coming to our local slab yard to pick your actual materials as natural stone varies so much. * located in Carrara, Italy; production is limited and controlled. Quarry Video: https://www.facebook.com/cmpsolmar.marmi.pregiati/videos/2762234760471059/
