Can you help make this a better article? What good localities have we missed? Can you supply pictures of better specimens than those we show here? Can you give us more and better information about the specimens from these localities? Can you supply better geological or historical information on these localities?

Below are some preliminary notes I have made about Aramayoite. This entry and thread has been made as a place holder for information that you will hopefully contribute about Aramayoite. It should be in no way be thought of as a claim I have staked out to write about this mineral, and in fact is an invitation for someone to step forward and create the article about this mineral. If you are so inclined and have questions about the format that such an article should have, go the The welcome topic at the top of the Best Minerals forum and read what has been posted there. Also take a look at some of the more mature articles that have already been written like Rhodochrosite, Adamite, Millerite etc. You will need also to pick out other images of Aramayoite that will go into the article.



Aramayoite
Ag(Sb,Bi)S₂ Triclinic


Aramayoitye, Micro and rare species coll ections.
Ag(Sb,Bi)S2
Bolivia
Potosi, Sud-Chichas , Chocaya, Anamas Mine. Found as aggregates of broad, thin plates, showing striations and frequently associated with pyrite, tetrahedrite, mirargyrite, argyrodite and stannite. There are about ten world wide localities for this mineral but for the collector this is the only important one. Ahlfeld’s Minerals of Bolivia, 1943 edition says that the mineral is very rare and was found in the Colorada vein in small eyes and that there were no crystals found suitable for measuring.

Crystals not pistols.

NB: Many reported "aramayoites" from other than the type locality (Chocaya-Animas) are really baumstarkites.

Sainte-Marie-aux-Mines has produced nice aramayoite crystals on matrix. A very fine specimen is on display at Berlin.
