Adamantine
Hardness:
2 - 2½

Name:
Named by François S. Beudant in 1832 in honor of Joseph-Louis Proust (26 September 1754, Angers, France – 5 July 1826, Angers, France), chemist and actor, for Proust's work on the red silver minerals (proustite-pyrargyrite series). He is most famous for discovering the law of definite proportion, stating that chemical compounds always combine in constant proportions.
Dimorph of:
Proustite-Pyrargyrite Series. The As analogue of pyrargyrite.
Trigonal dimorph of Xanthoconite.
One of the so-called "ruby silvers".

Based on recorded range of RI values above.
Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.
Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.
Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars.
