Stellerite is a rare mineral discovered by and named after Georg Wilhelm Steller, a German explorer and zoologist.

Zeolites, including stellerite, have been studied using a dehydration process to gauge the potential use of their phases as molecular sieves, sorbents, and catalysts.

[2] Stellerite is part of the orthorhombic crystal system which means it has three axes of unequal length that intersect at 90° angles.

Stellerite is more commonly found in rounded radiating clusters or as single crystals and appears more transparent than stilbite does.

[5] Stellerite is an anisotropic mineral, meaning that it has different properties in different directions-such as indices of refraction-when light passes through it.
