Can hematite scratch quartz?
No. Hematite (crystallized iron oxide) is 6.5 on the MOHS scale. Quartz (silicon dioxide)is 7.0.
Which of these is a mineral element gold hematite calcite quartz?
Gold, hematite, calcite, and quartz are all mineral elements.
What minerals are oxides?
Many minerals are oxides such as quartz and hematite.
Is hematite more expensive than smokey quartz?
Yes!
Can other minerals scratch the hematite?
Yes, other minerals can scratch hematite. Hematite has a hardness of 5.5-6.5 on the Mohs scale, so minerals with a higher hardness (like quartz or corundum) can scratch hematite.
