Knife block made of Nero Assoluto with rubies in the zoisite mother rock.

The correct term for a ruby is only red corundum. Like its sister mineral, the sapphire, the ruby is very hard. With a Mohs hardness of 9, it is only one level below that of a diamond, making it one of the hardest gemstones of all. The color of ruby zoisite is green and red, with black mica stripes in the stone.
The green areas are represented by the mineral zoisite, while the red areas in the rock are rubies. On closer inspection, you can sometimes see dark to black-green or grey-black mineral inclusions, which in turn are due to the mineral pargasite. The ruby rock was found in Tanzania. The fastening is gold-plated.

The Nero Assoluto natural stone is one of the most elegant of its kind. The black stone is a gabro, a magmatic stone of plutonic origin. Also known as plutonite, these stones are formed deep inside the earth, mainly in the oceanic crust. Among the gabbros, the Nero Assoluto Zimbabwe is a rare plutonic rock with the composition of a gabbro-plutonic stone. The special feature here is that this stone appears almost exclusively in black and is covered with tiny minerals.
