Lemon yellow, earthy masses of Avogadrite in a vial. The masses are around 1cm. Avogadrite is named after Amedeo Carlo Avogadro(1776 – 1856) an Italian physicist who determined the molecular theory that the number of molecules per mole of substance is exactly 6.02214076×10^23. It is otherwise known as "Avogadro constant". It is used to this day in chemical reactions. I use it all the time when I make pizza.
Avogadrite is a three locality mineral.
