Triphylite

2 in the gallery

Triphylite is a lithium iron phosphate mineral that forms in elongated, prismatic crystals and commonly shows a pale brown to pinkish brown color with a vitreous to submetallic lustre. The mineral’s habit tends toward slender, sometimes zoned crystals that can be exposed on matrix, with a degree of transparency that allows light to pass through thin edges. It occurs in granitic and pegmatitic environments, and notable specimens have been reported from localities in the United States, Brazil, and Portugal, among others. Collectors value Triphyllite for its delicate crystal form, gentle color, and the way it often appears as accent pieces within a matrix rather than as standalone aggregates.
