Know how to recognize them



Leucophanite is an inosilicate mineral with a complex composition, (Na,Ca)2BeSi2(O.OH.F)7. It may contain cerium substituting in the calcium position.

It occurs in pegmatites complexes as yellow, greenish or white triclinic crystals and has been found in Norway.

It was first described from the Langesundfiord district of southern Norway in 1840. The name is from the Greek leucos for "white" and phanein for "to appear" in allusion to the common white color.
