Key Differences
- ◆ Diamond (hardness 10) is the hardest known mineral; quartz rates 7 on the Mohs scale.
- ◆ Diamond is pure carbon (C); quartz is silicon dioxide (SiO2).
- ◆ Diamond has an adamantine luster; quartz has a vitreous (glassy) luster.
- ◆ Diamond has perfect octahedral cleavage; quartz has no cleavage and fractures conchoidally.
- ◆ Diamond is far rarer and more expensive; quartz is the second most abundant mineral in Earth's crust.
