Diamonds may be one of the hardest natural substances on earth, but that doesn't make them indestructible. A single blow from a hammer could shatter an exquisite gem into bits of rock dust in no time at all.

People often confuse hardness with toughness. While hardness relates to scratchability, toughness refers to how far materials can be pushed before snapping or breaking.


Diamonds are known to be some of the hardest materials on Earth, yet hardness doesn't equate to indestructibility. A diamond can still be crushed under sufficient force. That is why it is essential to understand the distinction between hardness and toughness; hardness refers to materials' resistance against scratching or chipping while toughness measures whether an impact reaches breaking point and cause deformations or cracks within them.

Although there are multiple methods of testing the hardness of minerals, one of the most popular ways is using the Mohs scale. This system ranks minerals based on their ability to scratch other materials - for instance if rock scratches something higher on the scale such as talc it is considered harder than its target material and considered harder than it. This testing method has become immensely popular and is used widely by geologists, geographers, gemologists, metalworkers and geological professionals worldwide.

The Hydraulic Press Channel is a popular YouTube video channel featuring one man and his 40-ton hydraulic press. They have posted videos showing it crush everything from bowling balls to non-Newtonian fluid, but their most captivating video shows it crushing an actual diamond within fractions of seconds! It truly amazes viewers to watch.

Cracked or chipped diamonds may be possible to break, but this process remains extremely difficult due to their unique atomic structure that forms an impenetrable lattice, meaning their atoms have little room to move or absorb an impact, thus shattering into many smaller pieces rather than cracking or chipping altogether when hit hard enough.

Hydraulic Press Channel provides an outstanding example of this. A 1.2 carat diamond was donated to them, and put under pressure with a 40-ton hydraulic press. While watching such destruction of diamonds may be fascinating, it should also serve as a reminder that diamonds aren't impervious and can be crushed with sufficient force from any source.


Diamonds are well-known as one of the hardest naturally occurring minerals on Earth, boasting a Mohs hardness rating of 10 on the Mohs scale of mineral hardness and possessing one of the strongest gemstones that can be formed into jewelry pieces. Though they possess such strength, diamonds can still be crushed under pressure with enough force, such as from hydraulic presses.

Answering this question with certainty doesn't involve breaking diamonds; rather, the reason a hydraulic press can break one is due to their toughness. Hardness refers to surface properties while toughness refers to their ability to absorb energy without cracking under stress.

Though diamonds may appear strong and resilient, due to their carbon crystal structure they are actually quite brittle and must be cut with each facet aligning approximately with an octahedral plane in order to avoid being crushed. Other minerals can be rotated and turned in order to create more favorable orientations but diamonds cannot do this as this would eventually weaken or chip them.

Due to this property, diamonds can actually be more easily crushed than many other materials such as coal and steel. Though some natural occurring minerals may be harder than diamonds, their lower tensile strengths render them more vulnerable to cracking under pressure than their counterparts.

Hydraulic Press recently conducted an experiment to demonstrate this truth; testing a 1.2 carat diamond with their hydraulic press revealed no surprise as the stone quickly disintegrated into dust.

As it turns out, diamonds aren't uncrushable after all - several naturally occurring and man-made materials such as tungsten and lonsdaleite have higher rupture toughness than them - yet hydraulic presses still make for powerful tools capable of breaking apart almost anything regardless of strength or hardness.


A hydraulic press is an efficient machine that relies on hydraulic fluid to generate and transmit force, used for flattening metal sheets, pressing bearings into casings, straightening bent metal pieces and creating intense downward pressure that can crush objects - an invaluable asset when producing diamonds in lab settings. It can flatten steel sheet, press bearings into casings or straighten bent pieces without creating damage to other objects in its path - among its many applications. However, its most notable application may be creating intense downward pressure that crushes objects - making this machine perfect for creating diamonds in lab settings!

There are various techniques used in laboratories for creating diamonds. Two popular methods include High Pressure, High Temperature (HPHT) and Chemical Vapor Deposition (CVD), both using extreme temperatures and pressures during their creation processes; these mimic the processes that occur naturally deep underground to produce natural diamonds. Both processes require large equipment capable of creating such conditions to enable diamond growth.

Diamonds are among the hardest naturally occurring minerals on Earth, but that doesn't make them indestructible. A well-placed hit from a hammer can crack or chip them due to their dense crystal structure which prevents its atoms from shifting or absorbing any impacts to it.

Diamonds are so fragile that it's possible to smash them with a hammer, as their low tensile strength means they have only very limited tensile strength. Other materials, like tungsten and steel are much stronger as their elastic modulus measures how far a material stretches before breaking.

YouTube user jaxman88 posted an excellent video showcasing a 1.2-carat lab created diamond being crushed using a hydraulic press, to incredible results, with over 11 million views! The diamond broke apart into pieces of dust proving its fragility despite being extremely hard.

Understanding the differences between hardness and toughness when discussing stones is essential. Hardness refers to surface properties while toughness measures how well a material withstands impact; although a diamond may appear hard enough for impact resistance, its toughness won't protect it against blows from hammers.


Hydraulic presses have the capacity to generate very high temperatures due to the pressure exerted. This is an essential factor as temperature has an indirect influence on material strength - high temperatures tend to weaken materials while low temps strengthen them further.

Temperature also has an enormous influence on how hard materials are, such as diamond, which is both hard and brittle; when hit with a hammer it disintegrates into piles of very small diamond dust. But when put through a hydraulic press it becomes much tougher - making it almost impossible to break even when hit with an enormous sledgehammer!

Because diamond's carbon atoms are bonded together tightly, in order to break it you need extreme forces and temperatures; making it nearly impossible to crush with a hammer alone but feasible with hydraulic presses.

Hydraulic Press Channel, an immensely popular YouTube channel, recently acquired a diamond and decided to crush it using their hydraulic press. They recorded this event using slow motion videography with macro lens captures; and the results are truly fascinating!

After using a thermal camera to monitor how crushing forces affected the temperature of a diamond, they used a hydraulic press to crush steel balls, box sections and smaller steel tubes with smaller surface areas than its larger counterparts. After crushing all three, a temperature change occurred that went from room temperature to above 140 degrees Fahrenheit for each object - with smaller objects heating up more due to having reduced surface area for heat dissipation.

Notably, this diamond is lab-created and while this video may be entertaining, it does not accurately represent what happens to natural and lab-created diamonds in real-life settings. Diamonds can become damaged from everyday wear and tear so having jewelry insurance in place for your diamond can protect it against unexpected problems.
