Are diamonds softer or harder than copper?
Diamond is the hardest known natural mineral on earth, raking top or 10 on the Mohs Scale of hardness. Copper ranks 2.5-3 on the same scale, rating it as much softer than diamond.
What is softer than quarts but harder than apatite?
Topaz is softer than quartz but harder than apatite on the Mohs scale of mineral hardness. It has a hardness of 8 on the scale, whereas quartz has a hardness of 7 and apatite has a hardness of 5.
Will quartz scratch a peice of copper?
Yes, quartz is harder than copper on the Mohs scale, so quartz can scratch copper.
What is the hardness of pegmatite?
The hardness of pegmatite can vary depending on its mineral composition, but it typically falls between 6 to 7 on the Mohs scale of mineral hardness. This means that pegmatite is harder than steel but softer than quartz.
Is onyx stronger than diamond?
