History and origin
Gabbro forms from the slow cooling at depth of silica-poor magmas, resulting in crystalline grain and dark color. Many black granites on the market are actually gabbros or similar rocks, extracted in various countries worldwide. The lot origin is not indicated in the catalog; Marmi di Carrara supplies it upon request.
Look and veining
The background is black or very dark gray, with fine or medium grain and small barely visible crystals. It's among the most uniform materials, with reduced variability between slabs. When polished it becomes intense, mirror-like black; when honed or brushed it takes on a matte anthracite gray.

FAQ
Is gabbro a granite?
Geologically it is a different rock, but commercially it is sold as granite because it has similar hardness and resistance.
Is it suitable for a kitchen worktop?
Yes, it is one of the most resistant materials; however, polished black shows fingerprints and drops, so many prefer the brushed finish.
Is it used for headstones?
Yes, black gabbro stones are widely used in funerary art for clearly legible engraving and stable polishing.
