Dark-green crystalline masse of ferroalluaudite within red quartz from quartz core of the pegmatite. According to my microprobe data, composition of the ferroalluaodite is Na.87Ca.56Fe"2.70Mg.56Mn.37P2.94O11.98, what is more close to the old ferroalluaudite formula NaCaFe"(Fe",Mn")2[PO4]3. Associating minerals are minor dark-brown rockbridgeite rosettes, grains of arrojadite-(KFe) and unidentified yet lustrous brown transparent phosphate - all they are concentrated in outer parts of the ferroalluaudite agregate. Specimen size is 6.5x6x2.5 cm. Collected by Stephano Cushet in 1994. Pavel M. Kartashov collection (#2216), analytical data and photo.
