About mgs
MGS (Marble & Granite Service) is an Italian natural stone sourcing and project management company headquartered near Verona, with a Phoenix stone boutique, Galleria of Stone AZ, at 750 E. Covey Lane #145. It keeps a warehouse inventory of slabs, a library of over 200 stone colors, and offers cutting, finishing, on-site measurement and installation for architects, designers, builders and private clients.
A supplier, not an installer
mgs sells slabs. It does not cut or install countertops itself, so it will not quote you for a finished kitchen. Choose your stone here, then hire a countertop fabricator to template, cut and install it. Ask the fabricator first whether it will work with a slab you bought elsewhere; some will only cut stone from their own yard.
