A hydraulic press is a machine that utilizes hydraulic cylinders to generate compressive forces and is widely used for crushing various objects - from diamonds to copper wire.

Diamonds may be known for their hardness, but that doesn't make them indestructible - even one hit from an ordinary hammer can damage a diamond and chip or break it.


Diamonds are well-known for their hardness, or ability to resist scratching. This quality makes diamonds ideal engagement rings because their stones will come into direct contact with skin. A diamond's hardness is determined by its atomic structure - its atoms are held together through covalent bonds which make separating their atoms extremely difficult.

Mohs scale measures the hardness of diamonds. This 10 point scale ranks minerals from softest (one) to hardest (10), with 10 being the hardest. A diamond scored 10 on this scale and can only be scratched by something with higher rating on Mohs scale such as steel hammers (hardness 5 or 6).

Geologists and gemologists employ the Mohs scale to measure the scratchability of minerals. First developed by Friedrich Mohs in 1822, it has become the standard way of classifying them. Hardness is determined by comparing minerals of equal category on this scale; for instance diamond is harder than quartz.

Although diamonds are hard and resilient, they can still be broken under extreme pressure and force, possibly fractured even. Therefore, when choosing jewelry with diamonds it is crucial that consideration be given to their hardness, cleavage, and tenacity when designing jewellery pieces.

There have been several methods developed for measuring material hardness. Popular methods include the Brinell, Rockwell and Vickers tests - these involve pressing a ball of steel or tungsten carbide into a sample at specific forces and calculating how big an impression was left behind via formulas.

People frequently misunderstand the difference between hardness and toughness. Many believe that diamonds are impossible to damage, yet this is far from accurate; diamonds can fracture, splinter, or break under high pressure - for instance when hit with a metal hammer they can even become cracked or even shatter under such pressure. Unfortunately this shows how diamonds do not match their hardness with toughness as many might believe.

Tensile strength

Diamonds may be one of the hardest materials on Earth, yet they are not impervious to force. A hydraulic press may even be able to shatter one. Therefore, it is essential that we understand the difference between hardness and toughness; hardness refers to materials' ability to resist scratching while toughness refers to their resilience against falls or impacts; this explains why even one of the strongest diamonds may be broken by blunt objects like hammers.

A diamond's strength is determined by both its chemical composition and crystal structure. Diamonds consist of carbon atoms bonded together through strong chemical bonds to form crystal lattice structures; these strong chemical bonds give diamond its incredible strength; however, with enough force exerted against them from an hydraulic press or similar tool it may break one apart.

Diamond is an isotropic material, meaning that its thermal conductivity remains consistent throughout. Furthermore, it boasts an extremely low specific heat which enables rapid absorption and release of heat - this makes it a popular choice in medical heating/cooling systems.

Recently uploaded to YouTube by Hydraulic Press Channel, an experiment saw them crushing a 1.2-carat diamond with a hydraulic press to see what would happen. Unsurprisingly, the diamond disintegrated into tiny fragments before being completely broken apart by impact and crushing pressure.

People often mistakenly assume diamonds are impossible to break. It is essential, however, to understand the distinctions between hardness and toughness of diamonds - hardness refers to resistance against scratching while toughness refers to resilience against impact and fracture - although diamonds are extremely hard they do not possess the strength of minerals like quartz and basalt which have harder surfaces and therefore don't suffer the same risks of cracking as easily.

Mother Nature knows exactly how to make diamonds. She begins by using carbon atoms, then subjecting them to extreme heat and pressure - typically within "diamond stability zones" which lie about 100 miles beneath Earth's surface. Because coal does not form within these conditions, diamonds cannot be produced from it.

Fracture strength

Fracture strength of diamonds measures the amount of pressure necessary to break them apart. Diamond's dense atomic structure makes it one of the strongest natural substances on Earth; furthermore, its hardness makes it ideal for many applications. Unfortunately, even its high tensile and fracture strengths cannot prevent it from being crushed under pressure and must therefore be protected against physical damage.

Hardness and toughness should always be differentiated. A diamond may be extremely hard, yet other minerals, like corundum or quartz are much tougher. Hardness refers to a substance's ability to resist scratching while toughness refers to its resilience against shocks or other forces.

Diamond's dense atomic structure means it does not provide much room for movement or impact absorption, making it nearly impossible to break it in full. But it may still be possible to chip one by striking with a hammer; such an impact will likely shatter it into multiple small fragments rather than dissolving completely into nothingness.

Diamond is a form of carbon bonded into an orderly crystal lattice structure. This allows its carbon atoms to reflect light, making diamonds appear transparent while other carbon-based materials like coal have darker hues.

Under intense heat and pressure, diamond can form silica as it undergoes microstructure modification that increases its strength and fracture toughness. While not visible to the naked eye, an electron microscope is necessary for its detection; it has many applications in high performance electronic devices, tribological applications, structural applications as well as corrosion prevention applications.

Diamond's crystal structure consists of carbon atoms arranged hexagonally, giving it strength against extreme temperatures and pressures. Bullets may even crack it - though this should rarely occur.

Elastic modulus

Diamonds are among the hardest natural substances on Earth, yet that does not make them indestructible. Under sufficient force - for example from a hammer blow or hydraulic press - diamonds can still be crushed by enough pressure; depending on their size and quality they could even withstand thousands of pounds before succumbing to cracking.

Elastic modulus is a property of solid materials that indicates how stiff or elastic they are, defined as the ratio between stress and strain - that is, force applied and material deformation - with higher numbers representing stiffer materials. Knowing about elastic modulus properties when designing structures can help predict their behavior under load or stress conditions.

Diamond has a much higher elastic modulus than metals and polymers due to the nature of atomic bonding present within each material, along with temperature variations and duration of stress or load exposure.

Diamond has an elastic modulus of approximately 125 gigapascals, significantly outstripping materials such as titanium and tungsten which only possess 45 and 407 gigapascals respectively. This can be explained by its core material being carbon while these other substances consist of carbon dioxide and nitrogen compounds.

Diamonds may be tough but can still be cracked with enough force if hit at an angle and with enough force. This is because diamonds possess an intricate atomic structure which forms a cubic lattice structure with very few spaces between its atoms that allows movement or absorbs impacts.
