How to recognize it

Tooeleite can be identified by its low hardness of 3 on the Mohs scale, which makes it easily scratched by a copper coin. It typically exhibits a green to yellowish-green color and a vitreous to dull luster. The mineral has a low density and may leave a pale green streak when tested.
