What are the top 5 hardest rocks?
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’s the hardest rock to break?
Since all minerals are also rocks, diamond is the hardest rock. Rocks that contain more than one mineral can't really have a single 'hardness' rating because each of the minerals they are comprised of will have a different hardness. For example, most granite is made up of quartz, feldspar, and mica.
What is the second hardest rock?
Corundum is the second hardest natural mineral known to science (1/4 the hardness of diamond). Gem varieties are sapphire and ruby.
What is the second hardest stone?

What is harder than a diamond?
The scientists found Q-carbon to be 60% harder than diamond-like carbon (a type of amorphous carbon with similar properties to diamond). This has led them to expect Q-carbon to be harder than diamond itself, although this still remains to be proven experimentally.
What is strongest stone?
Diamonds Diamonds are the hardest stone, while talc (for example) is a very soft mineral. The scale by which the hardness of minerals is measured is the Mohs Hardness Scale, which compares the resistance of a mineral to being scratched by ten standard reference minerals that vary in hardness.
Is Obsidian sharper than diamond?
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.
Are diamonds bulletproof?
Diamond Armor is certified bulletproof by NATO standards, waterproof thanks to nano-technology sealing and has an EMPA air conditioning system in-built to keep the wearer cool.
What’s harder than a diamond?
The scientists found Q-carbon to be 60% harder than diamond-like carbon (a type of amorphous carbon with similar properties to diamond). This has led them to expect Q-carbon to be harder than diamond itself, although this still remains to be proven experimentally.
Can obsidian cut through DNA?
They are used are used in modern medicine because the sharp blades create incisions which heal faster.
Is obsidian rare?
Obsidian is relatively unstable from a geologic perspective. It is rare to find obsidian older than about 20 million years, which is very youthful in comparison to most continental rocks that form the Earth's crust.
Is it possible to break a diamond with a hammer?
To say something is “hard” is not the same as saying it is “strong”. 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. Whether something is hard or strong depends on its internal structure.
Can anything break diamonds?
Diamonds are the hardest naturally occurring substance on earth. More information on diamonds. Diamonds are the most popular choice for engagement and wedding rings because they are almost indestructible, meaning it is nearly impossible to break a diamond.
What can destroy a diamond?
In a stream of oxygen gas, diamonds burn initially at a low red heat. They will gradually rise in temperature and reach a white heat. Then, the diamonds will burn uninterruptedly with a pale-blue flame, even after the removal of the oxygen heat source.
Is diamond sharper than 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.
Is obsidian used in eye surgery?
This month, Hardenbergh plans to begin using obsidian blades in a series of eye operations, primarily cataract procedures. Obsidian is a relatively rare product of volcanic eruptions. "It requires very specific conditions to form," Sheets says.
Is Crying obsidian real?
Crying obsidian is a decorative block that is used to create respawn anchors. They appear like purple blocks and these blocks produce purple dripping particles as if it is "crying".
Is blue obsidian real?
Blue Obsidian is a less common variety of Obsidian stone. In its natural form, it is a beautiful silica-rich volcanic rock. Blue Obsidian stones appear quite different from Black Obsidian and appear in a pale blue hue. It is a natural volcanic glass.
Can diamonds burn?
Although diamond requires a higher temperature to burn, it does indeed burn via normal carbon combustion. You can even burn diamond in a regular flame if you are patient and conditions are right. To accelerate the burning of diamond, you can give it more heat and more oxygen.
Can you burn a diamond?
Although diamond requires a higher temperature to burn, it does indeed burn via normal carbon combustion. You can even burn diamond in a regular flame if you are patient and conditions are right. To accelerate the burning of diamond, you can give it more heat and more oxygen.
Can lava melt diamonds?
To put it simply, a diamond cannot melt in lava, because the melting point of a diamond is around 4500 °C (at a pressure of 100 kilobars) and lava can only be as hot as about 1200 °C.
Can the sun melt a diamond?
However, you needn't worry about leaving a diamond in the sun. It would take a temperature of 700-900°C before it started to burn, since the carbon atoms in a diamond are in a tight three-dimensional array that's very hard to disrupt.
Can obsidian cut diamonds?
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 centimetre — an obsidian scalpel can equal diamond in the fineness of its edge.
Can obsidian cut your DNA?
They are used are used in modern medicine because the sharp blades create incisions which heal faster.
Can crying obsidian hurt you?
When mined, it will teleport/warp you to your spawn point. However, it will cause major fall damage (perhaps half health without feather falling) and if you attempt to teleport in the nether or end, it will kill you. If you die when attempting to teleport, your items will be lost.
Can you make a portal out of crying obsidian?
In survival mode, crying obsidian can only be mined with a diamond or netherite pickaxe, so be careful about that. Crying obsidian can't be used to make a nether portal. 1 Cracked Stone Bricks 55 Stone Bricks This portal can then be mined, providing a way of obtaining obsidian renewably.
