Crystals of scorodite can form dipyramids that look like octahedrons. These pseudo-octahedral crystals will also resemble the much harder gem mineral zircon . The color of scorodite is variable but it is most known and revered for its bright green or blue colors that really establish scorodite as a wonderful display mineral. Color is colorless, white, green, blue, yellow and brown. Luster is vitreous to sub-adamantine or greasy.
Crystals are transparent to translucent.
Crystal Habits include pseudo-octahedral crystals that are actually orthorhombic dipyramids. Also tabular crystals and fibrous and crusty coatings. Cleavage is very poor in a few directions. Fracture is conchoidal. Hardness is 3.5 - 4.
