Jadeite, Nephrite & Serpentine
This is why the material was used for tools and weapons as early as the Stone Age. Distinguishing features To distinguish »Nephrite« from other jade rocks or jade-like minerals, the density can be used. The minerals of the amphibole group, which includes actinolite / tremolite / »Nephrite«, have a density of 2.9 - 3.1. The hardness is 6 - 6½.

what can amphibolite be used for
For such rock associations the name banded amphibolite was used occasionally by some authors. As rock names, even with adjectives, can not be used for mixed or juxtaposed rocks of different petrographic types, these complex rock associations may be called an interlayered amphibolite and quartzo-feldspathic gneiss, or interlayered amphibolite
