Source: English Wikipedia. (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.

What is the toughest material?
Diamond is the hardest known material to date, with a Vickers hardness in the range of 70–150 GPa. Diamond demonstrates both high thermal conductivity and electrically insulating properties, and much attention has been put into finding practical applications of this material.
Do fake diamonds glow under UV light?
Fake diamonds may stay fogged for 2 seconds or longer according to National Jeweler’s Supply. Ultraviolet Light: About 30% of diamonds will glow blue under ultraviolet lights such as black light. Fake diamonds, on the other hand, will glow other colors or not at all.
What is the most strongest thing ever?
The World’s Strongest Stuff
- Diamond. Unmatched in its ability to resist being scratched, this much-loved gemstone ranks the highest in terms of hardness.
- Graphene.
- Spider silk.
- Carbon/carbon composite.
- Silicon carbide.
- Nickel-based super-alloys.
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 is the strongest mineral in the world?
Diamond is always at the top of the scale, being the hardest mineral. There are ten minerals in Mohs scale, talc, gypsum, calcite, fluorite, apatite, feldspar, quartz, topaz, corundum, and for last and hardest, diamond.
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 strongest natural material in the world?
Diamonds. According to the Mohs scale, the diamond is the hardest known natural mineral found on the planet. Coming in a various amount of colors, diamonds are used in a wide range of industries including, manufacturing.
Which gemstone is most powerful?
Diamond. It is not only one of the most expensive gemstones, it’s the strongest one.
What is the hardest mineral on Earth?
Diamond is the hardest known mineral, Mohs’ 10.
What Crystal is the hardest?
The Mohs Scale of Hardness
| 10 | Diamond |
|---|---|
| 9 | Corundum (rubies and sapphires) |
| 8 | Topaz |
| 7 | Quartz [Example: It scratches window glass] |
| 6 | Feldspar [Example: A steel file will scratch it] |
Is Obsidian a real thing?
Obsidian, igneous rock occurring as a natural glass formed by the rapid cooling of viscous lava from volcanoes. Obsidian is extremely rich in silica (about 65 to 80 percent), is low in water, and has a chemical composition similar to rhyolite.

What is the most unbreakable thing in the world?
Graphene, even in an imperfect form, remains the strongest material in the world, according to new research from Columbia University, which found that the single layer of latticed carbon atoms is virtually unbreakable even when stitched together like a quilt. Graphene is a one-atom-thick carbon layer.
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.
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).
Can you break a diamond with a hammer?
As an example, you can scratch steel with a diamond, but you can easily shatter a diamond with a hammer. The diamond is hard, the hammer is strong. This makes the diamond incredibly hard and is why it is able to scratch any other material.
What is the strongest material in the universe?
They found that nuclear pasta is the strongest material in the universe, which makes it possible for neutron star crusts to have crustal mountains that are tens of centimeters high.
What is the weakest material in the universe?
Talc is the softest mineral on Earth. The Mohs scale of hardness uses talc as its starting-point, with a value of 1.
What is the strongest animal on earth?
In brute strength, elephants are the strongest mammals and the strongest land animals. African elephants can weigh up to 6,350kg and they can carry up to 9,000kg, the weight of 130 adult humans.
What is the softest rock on Earth?
The name for talc, a sheer white mineral, is derived from the Greek word talq, which means “pure.” It is the softest rock on earth.
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.
Is there a material harder than diamond?
Diamonds remain the most scratch-resistant material known to humanity. The structure of boron nitride in its wurtzite configuration is stronger than diamonds. Boron nitride can also be used to construct nanotubes, aerogels, and a wide variety of other fascinating applications.
Can diamonds shatter if dropped?
Answer: It is very unlikely that a diamond would crack or break just by dropping it. Under the most severe circumstances, a diamond would probably chip under a hard blow. Don’t worry, it’s not a crack or a major inclusion that you missed when buying the diamond.
