harmotome
Extremely rare, technical/scientificSpecialized scientific/mineralogical
Definition
Meaning
A rare, complex hydrous barium aluminosilicate mineral characterized by its distinctive cross-shaped twin crystals.
Historically significant in mineralogy as the classic example of a 'cross-stone' due to its cruciform twins. It is primarily of interest to mineral collectors and specialists in zeolite group minerals.
Linguistics
Semantic Notes
The term is almost exclusively used within mineralogy and historical texts on crystallography. It carries no figurative or extended meanings in general language.

FAQ
Frequently Asked Questions
No, it is a mineralogical curiosity prized by collectors for its crystal form, but it has no significant value as a gem material.
It occurs in hydrothermal veins and cavities in volcanic rocks, with classic localities in Scotland, Germany, and Japan.
It derives from Greek 'harmos' (joint) and 'temnein' (to cut), referring to the appearance of its twinned crystals.
It would be highly unusual and likely confusing unless you are speaking with a mineral enthusiast or geologist.
