Diamonds may be one of the hardest materials on Earth, yet they're still susceptible to destruction; even with enough force a hydraulic press can crush them.

However, it should be remembered that hardness doesn't equal toughness: even with just one drop from a hammer a diamond can easily chip due to cleavage planes within its composition.


While diamonds are hard, they can still be fractured with enough force from blunt objects like hydraulic presses. While hardness measures the ability to resist scratching and breakage, toughness refers to resistance against breaking and bending.

Diamonds are one of the hardest naturally occurring minerals on Earth, making them perfect for cutting and polishing other minerals to enhance their beauty. Although expensive, diamonds can be found worldwide and made with hydraulic presses; however, you should first learn some key information before trying your luck at creating your own diamonds with one.

The Mohs scale is a standard that ranks minerals and metals according to how hard they are, with diamond being given 10 points while talc rated 1. Other minerals like ruby and sapphire also rank on this scale, though their hardness ratings are less intense than that of diamond.

As part of your decision when purchasing gemstones, it is essential to take note of their Mohs hardness rating as well as cleavage and tenacity. A mineral's hardness can be determined by its atomic structure - for instance in diamonds where carbon atoms are linked together into a cubic lattice structure which means each atom is relatively hard as there is little space for movement or impact absorption, making diamonds very resilient against knocks.

Minerals can be tested for hardness using a device known as a Shore scleroscope. This consists of a hollow glass tube mounted on a stand, into which an diamond-tipped hammer is dropped onto the sample and measured for its bounce height - with higher returns indicating harder materials.

The Hydraulic Press Channel is an immensely popular YouTube channel featuring people using industrial-sized hydraulic presses to squish everything from bowling balls and non-Newtonian fluid to precious stones in industrial-sized hydraulic presses. Their videos have amassed millions of views. One video in particular showcased them testing a diamond against their press, leading them to crush it predictably as expected; going viral, with many requests coming in for further tests of precious stones in their press.


Diamonds are widely recognized as being among the hardest materials on Earth, making them invaluable tools in law enforcement investigations and scientific laboratories alike. Detectives use diamonds to verify authenticity while scientists use them in laboratories to create indestructible industrial parts. But it's important to distinguish between hardness and toughness when discussing diamonds: hardness refers to an object's ability to resist scratching while toughness measures how easily something breaks or cracks; although diamonds are generally quite hard, they may still break or crack under sufficient force or at an incorrect angle or angle - an effect known as toughness which measures material's resistance to breaking or cracking; toughness measures how easily materials break or crack; while diamonds can withstand breaking or cracking even under extreme force compared with harder materials like talc or quartz;

Mohs scales are commonly used to measure the hardness of diamonds. This system rates materials according to how easily they scratch other materials; 1 (talc) to 10 (diamond), with 9 being softest and 10 being hardest. Only diamonds themselves can scratch other diamonds - though even then it would require considerable force!

One effective way of measuring diamond toughness is observing its rate of fracture under pressure. Each diamond contains four cleavage planes - points where its crystal structure weakens more readily - where breaking is more likely, yet even when struck at these weakest spots it still requires great force for breaking to occur.

One of the most intriguing methods by which diamonds can be broken is with a hydraulic press, as shown in this YouTube video with over 11 million views. By placing a 1.2 carat diamond under a hydraulic press and applying force from it to fracture it, scientist shows how even though diamonds are extremely hard, they can still be fractured by direct impact of a hydraulic press. While this experiment shows fractureability rather than toughness of diamonds it does show how easily one may fracture under pressure as any rough stone used will likely fracture under similar force as any faceted stone does due to its multiple faces redirecting and softening its impact force from hydraulic press pressure applied directly onto it by direct force of hydraulic press hydraulic press force applied directly onto it by redirecting force of hydraulic press to lessen its impact by redirecting force with ease into smaller impactful surfaces thus reducing impactful pressure applied directly on diamonds used herein.


Diamonds are among the hardest substances on Earth, composed of carbon atoms arranged into an intricate lattice held together with strong chemical bonds. While this makes them extremely hard, but also fragile - they can be crushed under pressure! - this makes diamonds extremely valuable and yet vulnerable.

Recent videos uploaded to YouTube have caused quite the buzz after showing a 1.2-carat diamond being crushed by a hydraulic press - this time for real. Diamonds typically have rupture toughness between 3000-3500 MPa - enough pressure to easily crush cars!

Before assuming that a hydraulic press can make diamonds, you should know that their material is not indestructible. To become diamonds, these materials must withstand massive stress and pressure to create their diamond form - this pressure exists everywhere we work and live, whether at work or home - it is important to remember that when utilized properly it can help us achieve success and help shape the future.

HPHT and CVD are two primary approaches to creating diamonds: both processes simulate conditions found deep within Earth's core where diamonds naturally form; both involve high temperatures and intense pressures to replicate this natural process.

These pressures typically range between 100 million and 1 billion pounds per square inch, and are necessary for forming diamonds as it causes carbon atoms to crystallize into an intricate structure.

Coal does contain carbon, but also includes elements such as hydrogen, nitrogen, oxygen, sulfur, arsenic and mercury that prevent its transformation into pure diamond. As such, it is not possible to craft diamonds from coal (although Superman appears to have done it through his hands).

To create lab-grown diamonds, an HPHT or CVD machine that can create the appropriate temperature and pressure is essential. There are various designs for these machines; belt presses are among the most widely used; they use upper and lower anvils to generate pressure of over one million pounds per square inch and can produce diamonds of different qualities in just a single cycle, but may take longer before reaching gem-quality sizes.


Diamonds may be the hardest natural substance known to humanity, yet they're not impervious to damage. A direct hit with a hammer or even light tapping against hard surfaces can chip or shatter them due to their inherent fragility due to being composed of carbon atoms bound together in such an unconventional fashion.

This unique bonding also helps determine a diamond's tensile strength, or amount of pressure it can endure before breaking. Tensile strength ensures a diamond does not crack from sudden impacts such as being dropped from height onto hard surfaces or crushed in hydraulic presses.

Shape, diameter, table size and depth all play an integral part in determining a diamond's overall size. For instance, a round-cut diamond with 5.5 mm diameter weighs 0.50 carats; its width at its widest point makes an impactful statement about its overall dimension.

The table size refers to the flat surface atop a diamond, typically measured in millimeters. Depth refers to the distance from its girdle to culet and also plays an influential role when considering diamond size.

Measuring a diamond's size requires extreme care, precision, and accuracy. A scale capable of accurately measuring in milligrams or an integrated diamond weighing tool with both grams and milligram readings must be used when taking measurements for size determination. Knowing its dimensions (length and width) is also crucial, with an ideal ratio between 1.25-2.25 serving as an indication of quality for an optimal length-to-width ratio that allows light transmission more effectively and increases brightness and sparkle of gemstone. Any diamond that falls outside this ideal range will look out of proportion; while too short may have shallow characteristics resulting in its size being affected.
