In fact, it is the most-popular dimension stone that is widely used all over the world.
What is the most hardest stone?
Diamond is the hardest natural material in the world. However, it’s also brittle. Scientifically speaking, hardness measures the ability to resist scratching, nothing more.
What stone is harder than granite?
Both granite and quartzite are very hard, but on the Mohs scale of hardness (from 1 to 10, with 10 being hardest) quartzite has the slight edge. It measures around 7 whereas granite measures around 6 to 6.5. While quartzite is slightly harder than granite, it’s important to understand that it’s not bullet proof.
Will a fake diamond sink in water?

Are Diamonds bulletproof?
It doesn’t seem unreasonable to wonder whether diamonds are bulletproof, since diamond is the world’s hardest natural material. Diamonds are not however bulletproof in general, as while they are hard, they are not particularly tough and their brittleness will cause them to shatter when struck by a bullet.

What rocks explode in fire?
The Most Dangerous Rocks in a Campfire Very porous rocks should be avoided, such as limestone, pumice, shale, and sandstone. Even these rocks have varying densities (even throughout a single rock), which means that some water could very easily get trapped inside, and crack or explode when heated.
What is the weakest rock?
Sedimentary rocks tend to be the ‘weakest’ of the three, as Igneous and Metamorphic rocks both undergo extreme pressures to form.
What is the rarest rock?
Painite : Not just the rarest gemstone, but also the rarest mineral on earth, Painite holds the Guinness World Record for it. After its discovery in the year 1951, there existed only 2 specimens of Painite for the next many decades. By the year 2004, there were less than 2 dozens known gemstones.
What is the only thing that can cut a diamond?

Can you melt a diamond?
In the absence of oxygen, diamonds can be heated to much higher temperatures. Above the temperatures listed below, diamond crystals transform into graphite. The ultimate melting point of diamond is about 4,027° Celsius (7,280° Fahrenheit).
What is harder than marble?
For instance, quartzite is a harder material than marble making it less prone to wear regarding staining and scratching. This may be important for areas like kitchen countertops where there is high traffic.

What can damage a diamond?
Sudden extreme temperature changes can cause damage, however. Diamonds can chip or fracture from hard impact, especially in areas where the carbon atoms are not tightly bonded. These areas, called cleavage planes, are the major source of damage to diamonds (figure 2).
What stone is better than a diamond?
White Sapphire is the clear winner in terms of a natural diamond alternative. Those choosing White Sapphire should expect white sparkle only as compared with the white and colored sparkle diamond offers.
