Etymology

Nickelhexahydrite is named after the element nickel, which is a key component of its chemical composition.

How to recognize it

Nickelhexahydrite can be identified by its low Mohs hardness of 2, making it easily scratched by a fingernail. It is typically colorless or white and has a vitreous luster. The mineral has a low density of 2.07 g/cm³, which is lighter than most common minerals. It does not have a distinct streak and is often confused with other soft sulfate minerals due to its similar physical properties.
