Oh my god, the opal in sandstone is one of the most beautiful rocks I've EVER seen! One of my passions is geology; &, therefore, ROCKS! (=
Are all of the rocks you post in your very own, impressive collection?
Also: I was curious what exactly you mean when labelling something like "Gypsum var. Selenium".
___ var.(iant? ) ___ = ?
Howdy! Thanks, that opal is indeed a pretty great piece. And yep, almost any original photo I post is from my own collection, with the exception of a couple pieces owned by my old supervisor at the U of A.
And close; the "var." that is often written in mineral names stands for "variety". So things like Selenite and Hackmanite are specific varieties of Gypsum and Sodalite (respectively)

Fluorite var. Stink Fluss on Quartz (+/- Hematite) aka Antazonite

–
When crushed, this material releases free Fluorine gas trapped within inclusions throughout the mineral. This creates a strong smell of ozone, leading to the distinct name.
