Nekoite is a triclinic, white silicate mineral consisting of calcium, silicon, oxygen and water. Its discovery was first published in 1956. ^{[2] [3]}

Etymology

Its name derives from reversing "Oken" from Okenite (named after the German naturalist Lorenz Oken), which it was originally mistaken for due to their similar appearances. ^{[3] [2]}

Properties

This translucent crystal is described as having a pearl white color. It is also said to have a vitreous (glass-like) lustre. ^[3]

Location

Nekoite is a very rare mineral, but has been found in Landsman Camp in Arizona; Crestmore Crestmore Heights in California; Koch-Bulach in Uzbekistan; and Caxias do Sul in Brazil. ^{[3] [4]}

Media appearances

It is featured in Stardew Valley as a minor item obtained from geodes.
