Diamond Facts: Features and Applications


A diamond is a mineral consisting entirely of carbon. The hardest natural material known to man, diamonds have been used as both an adornment and a tool since ancient times. 

While most diamonds are found in the earth’s crust, a small number are also found in meteorites. Diamonds form deep within the earth, about 100 miles below the surface. The high pressure and temperature transform the carbon into diamonds. 

Diamonds’ distinctive hardness, brilliance, and beauty make them suitable for many applications. This is from industrial tools to the most exquisite jewelry. 

In recent years, lab-grown or “synthetic” diamonds have also been used in various applications. But what are lab-grown diamonds? Keep reading to learn more about the different features and applications of diamonds!

All About Diamonds: Facts You Might Not Be Aware Of

Diamonds are known for their high quality, clarity, hardness, and sparkle. Pieces of jewelry made from these gemstones are a great choice whether you are looking for a gift or want to buy something nice for yourself. 

There are two major types of diamonds. These are the natural diamonds that are mined from the earth’s surface and lab-grown diamonds which are cultivated in laboratories. Both have the same physical and chemical properties. But still, you might wonder, “what are lab grown diamonds?”

These are diamonds created in the lab under the same conditions as the natural ones. This process is done by using modern technology that mimics the natural process. Both diamonds are formed when the carbon is compressed under high pressures and temperatures. Thus, all diamonds share some common features:

  • A diamond’s atomic structure makes it resistant to heat and pressure
  • Its hardness makes it resistant to scratching
  • Its reflective qualities make it an ideal gemstone for jewelry.

But what exactly makes diamonds so special?

Economical Hardness

Diamond is the hardest material known to man. It can be used to make a cutting tool that can cut through any other material, including ice. Diamonds are also used in cutting tools because they can withstand high pressures and temperatures in the mines where they are mined. 

The heat and pressure of drilling through rock or ice also break apart the diamond crystal structure. This allows for greater fracture force when applied to something harder than it was originally. The diamond’s high hardness makes it useful for cutting and polishing tools and drilling hard materials such as glass. The drill bit used in glass drilling will not crack or break under normal conditions but can easily be damaged by an abrasive diamond bit.

High Electrical Resistance

Diamonds have high electrical resistance. This makes them good conductors with other materials with lower electrical resistances. For example, a diamond will conduct electricity well in a copper wire. This is because the two materials share a similar electrical resistance.

Extreme Thermal Conductivity

Diamond is one of the most heat-conductive materials in the world. Its thermal conductivity is a whopping 473 W/mK at room temperature (300 °C). It conducts heat very well compared to other materials used in electronics today. This makes it useful for applications such as infrared sensors and thermoelectric generators. Most of these require high thermal conductivity to operate efficiently.

Diamond Is Transparent to Ultraviolet Light

Diamonds are transparent to ultraviolet light due to their high refractive index. The refractive index measures how much a substance absorbs or reflects light. The higher the number, the more efficiently it reflects light. 

A high refractive index means more light is reflected back into the eye than possible with a lower refractive index material. This property makes diamonds useful in industrial applications. They can serve as windows for detecting invisible traces of chemical compounds or radioactive isotopes.

Applications of Diamond In Several Industries

Diamonds are applicable in many industries. Some of the most common areas where diamond applies include:


Diamonds have been used as abrasives and cutting tools since they were first discovered. They are used to grind, polish, shape and cut metals. Diamond is used in the construction, mining, and machining industries.

  • Diamonds can be used in applications as diverse as grinding wheels for glass polishing to surgical tools. Diamonds are harder than steel and metals, making them perfect for cutting tools and drill bits.
  • They are also used in industrial abrasives for sandpaper manufacturing. Diamond abrasives are more effective because they last longer. They do not wear away quickly like different types of abrasives.
  • Diamond-coated saw blades cut through wood, plastic, and other materials. It doesn’t create splinters or gouges.
  • Diamond-coated electric motors reduce friction, improving efficiency and reducing equipment wear.
  • Diamond-coated high-intensity discharge lamps improve light output and decrease heat generation.


Diamonds can be polished to a mirror finish and set in jewelry to make beautiful jewelry items. Diamonds have many applications in the jewelry industry, but here are some of the most common ones:


  • Diamond stud earrings. Diamond stud earrings are trendy because they’re very bold looking. You can use them for both casual and formal wear.
  • Diamond bracelets. Diamond bracelets are another popular choice for diamond jewelry because they look exquisite and expensive. 
  • Diamond necklaces and pendants. Necklaces and pendants made from diamonds can add a lot of sparkle to an outfit or outfit combination. They also look great with other jewelry like pearl necklaces or earrings!
  • Diamond ring sets. Diamond ring sets include rings that match each other perfectly. They can be worn together as a set without looking mismatched! This is especially nice because it makes it easy to coordinate outfits. You can pair your rings with other pieces of jewelry that you like wearing together, like bracelets and earrings.

Other Applications

Diamonds are not only durable and strong but can also be used in electronics. Diamonds have been used in electronics for many years. One of the most common uses is for a diamond-coated magnet on a hard drive to prevent data from being erased. 


Diamonds are also used as electrodes in batteries and capacitors because they don’t deteriorate over time as other metals. These applications use small diamonds ground up into tiny pieces and then coated with another material, such as gold or platinum.



In a nutshell, a diamond is such an appealing gem because it has many properties that man has long admired and coveted, making it a prized commodity. Its practical applications make it highly sought-after. 

In addition, diamonds come in a variety of colors, each one with its unique appeal. Suppose you’re thinking about buying an engagement ring or any other type of diamond jewelry. You’ll want to ensure you have the necessary knowledge before entering the business. Add this versatile gem to your collection!
