Can You Make a Diamond With a Hydraulic Press?

Diamonds are famously hard, so can it really be possible to crush one with a hydraulic press? This video from Hydraulic Press Channel proves it can indeed happen!

However, it's important to keep in mind that hardness and strength are two distinct concepts. Hardness refers to how much a material resists being scratched while tensile strength refers to how far a material can stretch before breaking.

How to Make a Diamond

Hydraulic presses have long been revered on the Internet, and for good reason: their sheer power is impressive. Here, a video from Hydraulic Press Channel showcases one such press in action - crushing an exquisite diamond to dust in seconds flat!

The diamond in question is a 1.2 carat jewel worth at least $4,000 donated by a diamond retailer eager to capitalize on viral video trends. Unfortunately, its beauty and value won't make up for being featured by media.

Diamond is composed of carbon and is one of the hardest naturally occurring substances on Earth, yet hardness does not equate to strength, and even diamond can crack or break under pressure.

To understand this phenomenon, consider that diamond's atomic structure consists of an intricate cubic lattice that leaves little room for individual atoms to move or absorb impacts, making the stone extremely fragile and vulnerable to being broken by hitting it with a hammer or becoming caught up in jeans. This makes the diamond very brittle - thus leading to easy breakage when hit by external sources or caught between garments.

This also explains why even faceted diamonds may crack upon being dropped from great height. Ultimately, the force and angle at which it hits the ground will determine its degree of damage.

Lab-created diamonds can also be cracked or crushed when exposed to strong impacts; indeed, their fragility is even greater due to their vertical growth pattern, leaving less room for stretch-and-compression elasticity compared with natural counterparts and increasing risk of cracking or chipping under strong impact conditions.

So while it may seem miraculous that a diamond can be crushed by a hydraulic press, any material with enough pressure can indeed do just that. That is why man-made metals such as tungsten and steel are far stronger than diamonds; their higher tensile strength enables them to withstand more stress before breaking.

The Process

Diamonds may be one of the hardest materials ever known, yet that doesn't make them indestructible. Under enough pressure a diamond may crack or shatter; as evidenced in the video below by Hydraulic Press Channel's footage of a 1.2 carat diamond being broken up in their hydraulic press. Watching this incredible spectacle unfold is truly fascinating viewing!

Diamonds are first cut into smaller pieces using a saw with a blade impregnated with diamond powder, to cut them apart slowly and carefully. Once broken up into fragments they can then be rounded out using a lathe and later polished before becoming jewelry or an abrasive granule for cutting or grinding tools.

To create diamonds, extreme pressure and temperatures must exist simultaneously. Such conditions exist naturally within Earth's mantle where molten iron and carbon combine under immense pressure to form diamonds - an effect which scientists have replicated in their laboratories in order to produce gem quality diamonds.

HPHT stands for High Pressure High Temperature, and involves placing carbon into an extremely hot environment and applying very high levels of pressure. HPHT-produced diamonds have various applications ranging from drill bit abrasives and computer heat sinks to windows that withstand higher temperatures.

Regarding diamonds being crushed by hydraulic presses, it's important to remember that "hardness" doesn't equal "toughness". Diamond is actually quite fragile and will easily crack or chip under pressure from hard objects hitting in just the right spot; for instance, an aggressive blow from a hammer could shatter it like glass.

Though it is impossible to produce diamonds from coal, it can still be fascinating to explore what might happen if one attempted. Coal contains impurities such as water, hydrocarbons, silica, sulfur mercury and iron that prevent its creation as diamonds; however, under extreme pressure under a hydraulic press at very high temperatures it might still form diamonds; though this would take an inordinately long period of time for completion.

Materials

Diamonds are the hardest naturally occurring material on Earth, yet can still be crushed with enough force, such as from hammers or hydraulic presses. Watching videos by The Hydraulic Press Channel might show them taking down bowling balls or non-Newtonian fluid; here they tackle nature's hardest gem!

To create a diamond, carbon is needed. Carbon can be found naturally in coal, oil and trees but to turn carbon dioxide into diamond, you must submerge it deep within Earth's mantle and subject it to extreme heat and pressure - this creates an extraordinary network of carbon atoms bonded together in tight networks which gives diamond its strength but makes it nearly impossible to cut with traditional tools.

Chemical vapour deposition is an intricate and expensive process for creating synthetic diamonds, and requires large facilities and millions of dollars in investments to begin. While gem-quality synthetic diamonds can be produced using this process, some imperfections may still arise during production; for instance, if temperature or pressure during growth cycle is not precisely maintained then crystals could stop growing, become heavily included with impurities, or break off half way through their growth cycle.

Apart from its complexity, creating diamonds requires many steps and materials which are far too costly and energy intensive to be attempted at home or even in lab. Due to these restrictions, this research only occurs with limited scientists across the globe.

Hardness and toughness are often confused, with one another being measured differently. Hardness measures how easily a material scratches or breaks. A nail, for instance, is very tough and cannot be crushed with hydraulic press; however it could still be scratched by diamond.

Equipment

The diamond industry utilizes various equipment types to produce gem-quality diamonds of high-grade gem quality. All are based on a common principle, replicating conditions found deep within earth where natural diamonds form. There are two primary technologies used to produce these stones: HPHT and CVD, both using similar equipment but differing in pressure and temperature outputs.

Hydraulic presses are highly specialized machines designed to generate extremely high levels of pressure, unlike home shop models which take too long for diamond production.

Diamonds are composed of carbon atoms bonded together in an innovative fashion to form their crystal structure, giving the gem its indestructibility. However, even their hard surface can still be scratched or chipped by strong impacts from objects like hammers or even gradual pressure buildup over time. However, that doesn't make diamonds invincible! These objects can still be damaged with enough force; crushing may occur from being hit too hard, chipped from strong enough impacts, or broken under time due to buildup pressure buildup over time.

Diamonds remain one of the hardest materials on earth despite these flaws; however, many confuse "hardness" with "toughness": while diamond is certainly hard, its relative toughness compared to steel or titanium materials is somewhat lesser; crushing one would most likely shatter into multiple pieces since diamonds are fragile materials.

Due to this reason, diamonds are not indestructible and a hydraulic press can easily crush them. Diamonds can even be broken with normal hammers or by dropping them onto hard surfaces like granite. Furthermore, diamonds aren't nearly as resilient as the latest iPhone screen which could easily crack or scratch it when dropped on.

Hydraulic Press Channel YouTube videos don't aim to show how easy it is to make diamonds with hydraulic presses; their main goal is rather to showcase what amazing things their 40-ton hydraulic press can do and show its popularity among viewers through creative content such as crushing objects or making gummy bears, which has helped generate advertising and donation income from viewers. They have amassed an immense following thanks to this creative content; many viewers enjoy watching these entertaining clips!
