What is the strongest rock in the world?
The strongest rock in the world is diabase, followed closely by other fine-grained igneous rocks and quartzite. Diabase is strongest in compression, tension, and shear stress. If mineral hardness is the determining factor of strength then diamond is technically the strongest rock in the world.
What causes scratches on glass?
Scratches are the most common damage that your exterior window glass can incur. Scratches can be caused by several elements such as tree branches rubbing against the exterior glass. They could be caused by children, pets, or even be the aftermath of recreational activities.

What is the hardest precious stone?
A stone’s Mohs rating provides a measure of its scratch resistance to other minerals. Diamond is known to be the hardest and can scratch any other stone. Talc is the softest. Reference minerals in between include gypsum, calcite, fluorite, apatite, orthoclase feldspar, quartz, topaz, and conundrum.
What stone is harder than diamond?
Moissanite, a naturally occurring silicon-carbide, is almost as hard as diamond. It is a rare mineral, discovered by the French chemist Henri Moissan in 1893 while examining rock samples from a meteor crater located in Canyon Diablo, Arizona. Hexagonal boron-nitride is 18% harder than diamond.
Will diamonds scratch glass?
The Mohs scale is a scientific measurement of mineral hardness. Glass is rated a 5.5, and diamonds, the hardest mineral, are a 10. So, genuine diamonds will scratch a mirror. On the other hand, so will quartz (7), moissanite (9.25), and cubic zirconia (8).

Quartzite is one of the most physically durable and chemically resistant rocks found at Earth’s surface.
What is the hardest thing on earth?
(PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond.
Is Obsidian stronger than diamond?
Surprising Things about Obsidian Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon’s steel scalpel. It is 3 times sharper than diamond and between 500-1000 times sharper than a razor or a surgeon’s steel blade resulting in easier incisions and fewer microscopic ragged tissue cuts.
