About StelleriteHide

Formula:
Ca4(Si28Al8)O72 · 28H2O
Colour:
Colourless to white, pink, orange
Lustre:
Pearly
Hardness:
Specific Gravity:
2.13
Crystal System:
Orthorhombic
Name:
Named after Georg Wilhelm Steller (1709-1746), German explorer and zoologist.
Zeolite Group.
Easily confused with the chemically similar stilbite-Ca and other members of the stilbite subgroup.
Bladed crystals may be confused with colourless prehnite.

Stellerite is a zeolite mineral in the stilbite sub-group. It is the orthorhombic, Ca-rich end member of a series consisting of stellerite, the monoclinic stilbite-Ca and stilbite-Na, plus the Na-dominant, orthorhombic barrerite.

Stellerite can be found as individual crystals, as well as fan-, bow-tie-, sheaf-like and spherical aggregates that are also typical for stilbite-Ca. Stellerite has often been tentatively differentiated from stilbite-Ca on morphology. This is not a valid method, as stilbite-Ca can have the all the same shapes as stellerite (Deer et al., 2001). The only reliable method for distinguishing stellerite from the more common stilbite-Ca is a chemical analysis capable of identifying Na, in combination with an XRD study identifying the orthorhombic symmetry.

Although normally white, stellerite can be found in several other colors. The orange, pink and salmon colors often found in Garrawalla, Australia, are due to minute inclusions of hematite. Celadonite, or other clay inclusions, may give give greenish grey colors.

The most attractive crystals are found in cavities in basalt, but stellerite is also found in hydrothermal systems in a wide variety of host rocks, such as hornfels, granites, granitic gneiss, pegmatites, amphibolites etc.
