Etymology[edit]
From French aplome, from Ancient Greek ἁπλόος (haplóos, “single, simple”). Coined by French priest and mineralogist René Just Haüy in 1801.[1]
Noun[edit]
aplome (uncountable)
- (mineralogy) A brown or green variety of andradite containing manganese.
- 1912, Edward Salisbury Dana, A Text-book of Mineralogy with an Extended Treatise on Crystallography and Physical Mineralogy, New York: John Wiley & Sons, E.2.(b), page 417:
- Aplome (properly haplome) has its dodecahedral faces striated parallel to the shorter diagonal, whence Haüy inferred that the fundamental form was the cube; and as this form is simpler than the dodecahedron, he gave it a name derived from ἁπλόος, simple. Color of the original aplome (of unknown locality) dark brown; also found yellowish green and brownish green at Schwarzenberg in Saxony, and on the Lena in Siberia.

- Les stries dont leurs faces sont sillonnées, semblent indiquer qu’ils ont pour forme primitive un cube, qui passe au dodécaèdre rhomboïdal, en vertu d’un décroissement par une simple rangée sur tous ses bords ; résultat qu’aucune autre substance n’a encore offert complétement, c’est-à-dire, de manière que le décroissement atteignît sa limite ; et comme il est en même temps si simple et si élémentaire que je l’avois choisi pour le premier de tous, en exposant la théorie relative à la structure des cristaux (I), j’en ai déduit le nom d'aplome'’, dont on pourra se servir, en attendant que des observations plus décisives ayent marqué à la substance qu’il désigne sa véritable place.
