There are things around the world that look almost exactly the same but are very different. A very common and basic example is sugar and salt. Look the same, but we know one tastes salty and the other tastes sweet. Similarly, other things are also present around us, having similar appearances but different features and properties like diamonds and crystals.

Diamond vs Crystal

The difference between Diamond and Crystal is that diamonds are made up of carbon atoms and Harsh made in nature under very critical conditions. In contrast, crystals can be made up of anything, such as crystallization made up of sugar syrup or even salt crystals extracted by depositing ocean water.

Diamonds are a beautiful creation of nature and are very complex in themselves. Diamonds show a brilliant property of reflection of light shining and beautiful. They are also the hardest material mountain nature. Diamonds are so hard they are even used for cutting glass. At the same time, they are really expensive too.

On the other hand, Crystals are solid materials having a very well-organized molecular structure. Molecules fit together in a repeating pattern which results in giving them unique shapes. They are formed when a liquid cools down and starts hardening, and this whole process of cooling down a liquid and then hardening to become a crystal is known as crystallization.

What is Diamond?

Diamond is a rare natural mineral that constitutes carbon atoms. The covalent bonds are formed by carbon atoms in a beautiful arrangement where one carbon atom is surrounded by four other carbon atoms, making diamond a simple yet strong bonded material. 

It has many unique properties that make it a versatile substance. Diamond is known to be the hardest substance that occurs in nature. It has high chemical resistance, excellent electric conductivity as well as high thermal conductivity too. But the best property for which diamonds are so well known is their lustre. The optical properties of diamond, like high dispersion and high refraction index, make it appear so lustrous that it is very pleasing to the eye. 

Diamond being an all-rounder is used in several fields, from making speciality lenses for works that require high-performance and long durability to making the most magnificent jewellery famous worldwide. Diamonds are so hard that they are even used for cutting glass and other such materials. Although they are very costly since there is a green substance and diamond cutting and polishing are very skilled jobs that require a highly trained person who can enhance the reflecting properties of a diamond and cut them so that they become even more beautiful.

What is Crystal?

Crystals look very similar to diamonds and therefore are often mistaken. But a crystal is very different from diamonds in many ways. Crystals are seen as a special kind of material where the molecules fit together in a repetitive pattern. These are the patterns that result in giving the crystals different unique types of shapes. They can lose their lustre if left unattended for a long time.

Unlike diamonds, they are not a very good conductor of heat and electricity and therefore could not be used in any other work apart from making jewellery and other attractive structures. Crystals are also found in nature, but the process of making them is not very complex. They are simply made when a liquid cools down and then starts to harden. When they are completely hard, they become a crystal. The liquid molecules joining together in a uniform and repetitive pattern ultimately gives crystals the beautiful appearance they have. This complete process of cooling down liquid molecules and then hardening them to become a crystal finally is known as crystallization. 

They are not very expensive when compared to diamonds. Crystals are seen as the most beautiful naturally occurring substance and have a great variety. They can be simply made when water freezes into ice in clouds and comes down in the form of snowflakes. Or in industries, sugar syrup and saltwater is cooled down to form sugar crystals and salt crystals, respectively, that we use at home in daily life.

Main Differences Between Diamond and Crystal

  1. Diamonds are the hardest naturally occurring substances, while Crystals are brittle.
  2. Diamonds consist of carbon atoms covalently bonded together, whereas crystals are made when a liquid cools down and hardens.
  3. Diamonds are an excellent conductor of heat as well as electricity. Crystals are not good at conducting heat or electricity.
  4. Being a rare element and having many valuable properties, a diamond is costly. Crystals are not so expensive when compared to Diamonds.
  5. Diamonds have the best reflective index, and crystals do not. This property can be used to distinguish between the two very easily.

Conclusion

When we look at a diamond and a very well curated crystal at the same time, it might be a bit difficult to distinguish between the two. Since a lot of crystals have a very similar appearance to diamonds, it becomes a common occurrence of thinking of them like one another.

But they’re very different and have unique properties of their own. A person who deals with crystals or diamonds on a daily basis can easily distinguish between these two just by having a glance at them. Diamonds appear way brighter than a crystal and are even good conductors of heat and electricity, which makes them far more useful than a crystal.
