These rare phosphate minerals are usually brightly colored and make wonderful mineral specimens. Some mines have been made famous by their suites of unusual and beautiful secondary phosphate minerals such as eosphorite , reddingite , sicklerite , hureaulite , fairfieldite , dickinsonite , stewartite , vivianite , salmonsite , strengite , purpurite , heterosite , phosphoferrite , wolfeite , triploidite and fillowite to name a few. This fact makes lithiophilite an appreciated mineral. Lithiophilite forms a solid solution with the often associated mineral triphylite . Lithiophilite is slightly less dense and is pinkish to greenish brown whereas triphylite's color tends toward blue and blue gray.
Color is pinkish to greenish brown.
Luster is vitreous. Specimens are transparent to translucent. Crystal Habits do not include well formed crystals because most crystals are embedded and appear as compact, cleavage masses and intergrown crystal clumps. All cleavages are at right angles to each other. Fracture is uneven.
