Can Obsidian cut through diamond?
Cutting edge Obsidian – a type of volcanic glass – can produce cutting edges many times finer than even the best steel scalpels.
At 30 angstroms – a unit of measurement equal to one hundred millionth of a centimeter – an obsidian scalpel can rival diamond in the fineness of its edge..
Can anything 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 the hardest thing to melt?
TungstenTungsten is known as one of the toughest things found in nature. It is super dense and almost impossible to melt. Pure tungsten is a silver-white metal and when made into a fine powder can be combustible and can spontaneously ignite.
Is there anything 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 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 can cut diamond?
Diamonds are cut with specialized tools that make use of diamond tipped phosphor bronze or diamond dusted steel blades. Such tools are used to exploit the structural weakness of the diamond by grooving and striking along specific tetrahedral planes.
What is the weakest material on earth?
According to the scale, Talc is the softest: it can be scratched by all other materials.
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 We Make Diamond at home?
Synthetic diamonds are made at about 300deg C, but usually in a pressure vessel using microwave radiation and a “seeding” crystal. You can make diamond as big or small as you want by growing them in a chemically neutral environment (nobel gas/ nitrogen) using CO2. Check out wikipedia, has an article about them.
Is there a rock harder than diamond?
(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.
Can a diamond stop a bullet?
Pound for pound, diamonds are not very good at stopping bullets. The energy absorbed by diamond shattering is much less than the energy absorbed by metals deforming. A plate of steel would be better at stopping bullets than a plate of diamond.
Do diamonds melt in lava?
The melting point of Diamond at about 100,000 atm is 4200 K, which is much higher than the temperature of lava. So, it is impossible for lava to melt a diamond. … So, if the temperature of lava is above this, the diamond will burn (not melt).
What is the hardest thing on earth?
Diamond is the hardest naturally occurring substance found on Earth. But it is not the hardest substance. Wurtzite boron nitride (synthetic) and lonsdaleite (which comes from meteorites) are both harder.
Will sandpaper scratch a diamond?
Diamonds are among the world’s hardest stones. Consequently, it wouldn’t be scratched by the rough surface of the sandpaper. The most common “fake” diamond is cubic zirconia. If you scratched it with a sandpaper it would scratch up just like any other material that is not a diamond.
What is the strongest ore on Earth?

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.
How do you destroy a diamond?
Diamonds are very brittle, they’ll crack easily if struck. You can also burn them in oxygen since they’re made of carbon. The easiest way to destroy it would probably be just to burn it in a crucible; it’s just coal. You turn it into carbon dioxide just likr burning coal.
Can a fake diamond sink in water?
Real diamonds are incredibly dense, and often outmatch the fakes in density tests. To confirm this, fill a glass up with water and drop your diamond in. A fake diamond will most likely float on top or only sink to the middle while a real diamond will sink to the bottom thanks to its density.
What is the softest mineral on Earth?
TalcTalc is the softest and diamond is the hardest. Each mineral can scratch only those below it on the scale.
What happens if you melt a diamond?
At ~700 degrees Fahrenheit the diamond will start burning. This will produce Carbon Dioxide and change the structure so that it is no longer a diamond. As diamond is made of Carbon, it would revert back to that form while losing its mass to the production of CO2. This is due to the presence of Oxygen.
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.
