Kininiowy

Kininiowy is a rare and unique mineral that was first discovered in the late 19th century in the Kini Hills of Tanzania. It is a form of calcium silicate with the chemical formula CaSiO3. The mineral is typically colorless or white, but can also exhibit shades of yellow, green, or blue due to impurities. Kininiowy is known for its translucent to transparent appearance and its vitreous luster.

The mineral is orthorhombic in crystal structure and can be found in metamorphic rocks, particularly in contact metamorphic zones. It is often associated with minerals such as diopside, tremolite, and calcite. Kininiowy is relatively soft, with a Mohs hardness of 5 to 5.5, and has a specific gravity of approximately 3.2 to 3.3.

Due to its rarity and unique properties, kininiowy is of interest to mineral collectors and geologists. However, it is not commonly used in industry or jewelry due to its softness and lack of significant aesthetic value. The mineral's name is derived from the Kini Hills, where it was first discovered, and the suffix "-owy," which is a common ending for mineral names in Polish.
