Diamonds are well-known as one of the hardest materials found naturally. But this doesn't make them indestructible - one bad blow at an unfavorable angle could crack or chip it easily.

As evidenced on YouTube by the hydraulic press channel, when 1.2 carat diamond was put under their powerful hydraulic press and it broke. This was due to diamond's unique combination of hardness and rupture toughness (approximately 3000 MPa).


Diamonds may be one of the hardest natural materials on Earth, but this doesn't make them indestructible. Under certain conditions, diamonds can still be broken and shattered into tiny shards by pressure from a hydraulic press; an incredible sight to witness! One popular YouTube channel known as The Hydraulic Press Channel specializes in crushing various objects using its 40-ton hydraulic press with slow motion recordings; they have crushed everything from Nokia phones to bowling balls and toys before taking on real diamonds recently as their latest challenge!

Diamonds are composed of carbon atoms arranged in an ordered lattice to form their structure and give them their hardness. To mark a diamond, its atoms must be moved - this requires extreme effort, with enough pressure being applied on one area to successfully move all atoms within it.

Diamonds can be difficult to scratch due to their hard surface. But it is important to remember that hardness of a diamond only measures its resistance against scratching; other means may lead to its crushing and shattering as well.

Diamonds boast an excellent tensile strength, although it may not match that of manmade metals such as steel or tungsten. A direct hit from a hammer is enough to break them very quickly due to their strong atomic bonds which outshone those of other materials.

Keep in mind that just because a diamond is hard doesn't mean it cannot be broken apart or crushed, and crushing one under certain circumstances is relatively straightforward. A powerful blow such as a hammer strike or even the weight of a car could destroy one easily.

Liquid water at high pressure can fracture diamonds. High temperatures and pressures may also shatter them; melting may occur if exposed to temperatures exceeding 3500 degrees Celsius and pressures that exceed one million times atmospheric.

Tensile strength

Tensile strength of diamonds should be an important consideration when purchasing gemstones. Diamonds are the hardest naturally occurring material on Earth and can withstand significant pressure without breaking; however, this does not apply if applied at an inconvenient point or angle; that is why having a good jewelry insurance plan in place to cover any costs due to accidental damage is so essential.

A diamond's tensile strength is determined by its carbon atom bonds, which play an essential role in its durability and resistance to breakage. Though diamonds are generally strong stones, under certain conditions they can still be crushed; indeed if hit hard enough with enough force they may even be broken by hydraulic presses!

Diamonds are extremely hard, yet not as tough as engineering materials like tungsten and steel. While they can withstand immense pressure, sudden temperature changes or direct impact may break them.

Hydraulic Press Channel on YouTube has been making headlines by breaking all sorts of objects with their hydraulic press, such as golf balls, phones, books and even diamonds donated from rich individuals. They even used their machine to break a 1.2 carat beauty donated from one such generous individual - it was quite spectacular to witness!

This video offers an excellent demonstration of how a press can break a diamond into smaller pieces, showing its atomic bonds unravelling while being crushed and its fragments emerging from its shell as small holes form on its crystalline structure. Although diamond is an extremely hard natural substance, its strength does not match that of paper.

Hertzian indentation provides an accurate measure of diamond's tensile strength, with an average value for each diamond coming out to 20 GPa on average. This figure falls far short of first principle predictions or Griffith theoretical tensile strengths of 122 GPa due to inelastic relaxation and premature microcrack failure.


Diamonds may be among the hardest natural materials on Earth, yet they're not indestructible. Under certain conditions such as high pressure and temperature extremes, diamonds can be crushed under intense strain; similarly they can also be compromised by acids or chemicals which break down carbon atoms' atomic structures, weakening their crystalline structures and ultimately leading to their breakage.

Diamonds can withstand significant pressure before breaking, though the exact amount depends on its size and quality. Shear forces tend to be less harmful to diamonds than compression forces - in fact, diamonds have greater resilience to shear forces than metal plates can withstand.

The Hydraulic Press Channel on YouTube has quickly become famous for using hydraulic presses to squash objects with force, from bowling balls to non-Newtonian fluid and even nature's hardest material - diamond. Watching their videos mesmerizing. Using a 4 ton hydraulic press capable of producing up to 144 tonnes (142 long tons; 159 short tons), they create forceful compression of objects up to an amazing 159 short tons in force.

Hydraulic Press Channel received a 1.2 carat diamond, which they placed into their hydraulic press. It's quite mesmerizing to watch as the diamond slowly meets its end - eventually cracking and shattering under pressure from this immense hydraulic press.

Scientists had predicted that diamond would crack under high pressure, yet this did not happen. Through experiments involving diamond anvils, scientists were able to compress a diamond up to 2 trillion pascals -- five times greater than Earth's core pressure-- enough to break it apart but not create new crystal structures.

Although diamonds can be crushed under extreme circumstances, this process is rarely easy. Their atomic structure protects them against scratching but not crushing. But repeated hard hits may chip off their weak points (cleavage planes). Therefore it is wise to store your diamond in a safe place when not being worn for fear of accidental impacts which could damage or destroy it completely.


Diamonds may be one of the hardest substances on Earth, but that doesn't make them indestructible. There are multiple methods by which diamonds can be broken; an interesting one being hydraulic presses. YouTube channel Hydraulic Press Channel has recently made waves by crushing everything from bowling balls and plasticine models to real diamonds in their press - even one 1.2 carat diamond!

Hydraulic Press Channel's video showcases its powerful hydraulic press in action by subjecting several objects to it and watching as they shatter before their eyes. It's fascinating and gives an incredible perspective into what happens when something reaches its limit of strength; plus it helps illustrate just how difficult it would be to break a real diamond using traditional tools.

Hydraulic Press Channel has quickly gained in popularity over recent months, as people watch in anticipation of what it can crush next. Their previous experiments involved crushing phones and bowling balls; now, however, they took on one of nature's hardest materials - diamond! Their video shows results of this experiment; be sure to watch.

People typically damage diamond jewelry through knocks and blows. While diamonds won't shatter when dropped, they may chip under strong accidental impacts; this is particularly true of sharp point diamonds which don't tightly connect with other atoms in their structure.

Diamonds can also be broken by shear forces, which cause the stone to fracture or split in two. While this doesn't happen often, it is still possible for this method of breakage to damage a diamond; therefore it is wise to wear diamond jewelry with care when lifting heavy objects or participating in physical activities that involve working out or exercising.

Diamonds can also be broken by burning or melting them. While this is rare, some conditions could allow a diamond to burn such as being exposed to fire or using a jeweler's torch on it; but, the chances of this occuring are minimal.
