Notes. Like rutile, ilmenite is quite variable in nature.Actually, more variable since it would likely come from the same deposit, it being the more iron-stained part. You can tell the difference between granular rutile and granular ilmenite by doing a smear test against an abrasive surface (i.e. an unglazed white tile).

Ilmenite is a black mineral found in mafic igneous rocks and pegmatites. It belongs to the iron titanium oxide minerals group, which also includes rutile, anatase, brookite, and perovskite. Ilmenite has a hardness of 5.5-6 on the Mohs scale, making it durable enough for use as an abrasive or gemstone polish.
