An exquisite marble fireplace mantle has a left marble pillar (1) and a right marble pillar (2) positioned vertically on a marble slab base (3) at a predetermined distance from oppositely disposed marble front walls (4, 5) of the fireplace mantle and extended to positions of support of marble display shelving (6, 12, 22) proximate a top of the marble fireplace mantle. Vertical and horizontal components are made of marble slabs that are cut to shape and grooved for tongue-and-groove fitting of adjoining joints of all-marble components that can have ground and polished visible surfaces. Selected vertical components that rest on horizontal surfaces are location-pinned in place.
