Brazilianite

Brazilianite is one of a few phosphate gems.

Chemical Formula: H₄Al₃NaO₁₂P₂

Other names: Sodium trialuminium tetrahydroxide bis(phosphate(V))

Layman's explanation: Brazilianite was discovered by Alfredo Severino da Silva in 1942 and was later identified by Frederick Pough and Edward Henderson in 1945. This rare gem has been found to be pale yellow to yellow-green in color and can be found in phosphates that are rich in pegmatites. This phosphate can also occur as components of fillings in sedimentary rock and in some paleocave deposits. The mineral is generally found in the caves of Brazil, New Hampshire, Maine, and Yukon Territory, Canada.
