About Bussyite-(Ce)
Formula:
(Ce,REE)3(Na,H2O)6MnSi9Be5(O,OH)30F4
Colour:
Pale pinkish orange
Lustre:
Vitreous
Hardness:
4
Specific Gravity:
3.00
Crystal System:
Monoclinic
Name:
Named J.D. Grice, R. Rowe, G. Poirier, A. Pratt, J. Francis in 2007 in honor of Antoine Alexandre Brutus Bussy (29 May 1794, Marseille, France – 1 February 1882, Paris, France), chemist, who is co-credited in isolating the element beryllium, which is a component of this mineral, in August 1828. The "-(Ce)" suffix is in allusion to cerium being the dominant rare earth element in the species.

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. Each grain retains its interference colour (retardation) while its brightness falls to black at extinction and reaches a maximum between extinction positions.
