settingits

Settingits, also known as settingite, is a rare mineral that was first discovered in the 19th century. It is a complex borosilicate with the chemical formula (Na,Ca)2B4Si2O12. Settingits are typically found in volcanic rocks and are often associated with other minerals such as nepheline and sodalite. They are named after their setting, or location, in the host rock.

Settingits are usually colorless or white, but can also be found in shades of blue, green, or yellow due to the presence of impurities. They have a vitreous luster and a hardness of 5.5 to 6 on the Mohs scale. Settingits are typically found in the form of small, prismatic crystals or in massive aggregates.

The mineral is of limited interest to collectors and is not commonly used in jewelry. However, it is sometimes used in the production of glass and ceramics due to its unique properties. Settingits are also of interest to geologists and mineralogists due to their rarity and the geological conditions under which they form.

Settingits are not considered to be a significant source of any particular elements, but they do contain small amounts of sodium, calcium, boron, and silicon. These elements are important in a variety of industrial and technological applications.
