Knife block made of Nero Impala with a holding hole for wooden spoons

Nero Impala impresses at first glance with its elegant, uniform appearance. This natural stone is an anthracite-colored to black natural stone and belongs to the Gabbro rock family. From a petrological point of view, it is also a norite. Norites are formed from metal-containing melts in the upper earth's crust. The South African rock plate, which also contains Nero Impala as a rock material, extends over a huge area of 66,000 km² and is one of the largest rock deposits of its kind with the world's largest raw block mining volume of a hard rock of 150,000 m³, but only 10 to 12% of the mined rock volume consists of Nero Impala and can be used for further processing. The predominantly 90% mined norite rock from this huge rock formation contains large ore deposits, the largest known deposit of platinum in the world, and over half of the world's chromium deposits as well as the world's largest vanadium deposit.
