He sent samples of this stone to the famous German mineralogist, Abraham Gottlob Werner. He named this stone zoisite in honor of its discoverer, Sigmund Zois. The name ruby comes from the Latin "rubeus" meaning red. It is an extremely hard red gemstone, which owes its color to the presence of chromium atoms. The name ruby zoisite comes from the association of these two natural stones: green zoisite and red ruby. Black spots can also be seen, which are actually inclusions of hornblende, a generic name for a group of silicates. Ruby on zoisite is sometimes referred to as anyolite stone. The ruby extracts found in zoisite stone are mostly low-quality rubies, making its price very affordable. Ruby zoisite is a mineral with very few myths or legends associated with it. However, in East African oral traditions, elders speak of a magical green stone, speckled with black and red. This stone was reputed to provide abundance to hunters and protect them from various dangers encountered such as wild animal attacks or bad weather. Some even believed that this stone had the power to make its wearer invisible. Ruby has a hardness of 9 on the Mohs scale, and zoisite ranges between 6 and 6.5 on the same scale. Ruby zoisite owes its other name anyolite to a significant deposit discovered in Tanzania in 1954. Its name is derived from the Maasai "anyoli" meaning green. It has been mainly used for setting jewelry or being carved into ornamental or religious objects. Zoisite is composed of aluminum and calcium silicates, while ruby inclusions are composed of aluminum oxide and belong to the corundum group. Nowadays, ruby zoisite is mainly used in the manufacture of jewelry (pendants, bracelets, etc.) or objects in lithotherapy. Indeed, it is particularly appreciated in lithotherapy due to its blend of stones with multiple benefits. The main deposits are located in Tanzania, Australia, India, Mexico, etc. In lithotherapy, ruby zoisite is a stone that stimulates vitality and provides motivation.
