If you’ve been spellbound by the magical beauty of diamonds, let us tell you something, you’re not alone!
But, have you ever wondered how these glistening gemstones originate and what makes them so coveted? If yes, you’re in the right spot!
In today’s blog, we’ll unleash everything you might want to know about diamonds before purchasing a diamond jewel (or simply fulfilling your thirst for learning more about them). Read on to know more!
As we know, diamonds are one of the hardest materials on the Earth with a solid rating of 10.0 on the Mohs scale. However, how they originate is still a mystery for many.
Contrary to the popular assumption, diamonds are NOT made from coal. It’s time that we break the common myth surrounding diamonds; that diamonds are the result of coal evolving inside the Earth under extreme heat and pressure. In reality, diamonds are much older than the Earth’s plant material, the primary ingredient for coal creation.
So, how do these glistening gemstones originate?
Simply put, when carbon deposits inside the crust of Earth are subject to extreme heat and temperature, it results in the formation of diamonds. In this process, some stones may take shape in a matter of days while others may take millions and billions of years to materialise.
Interestingly enough, most diamonds date back approximately 1 to 3 billion years. Also, it’s important to note that diamond formation is not an uninterrupted process. Due to a change in temperature or pressure, the diamond’s formation can be disturbed. As a result, it might have to wait for hundreds to a few million years for the conditions to become suitable for growth.
The rough diamond occurring through this process can either be colourless or coloured. During the formation of diamonds, the trace elements in the surrounding are responsible for the colour of diamonds.

So, once the rough diamond is formed, it is brought to the Earth’s surface through volcanic activities. South Africa, Canada and Russia are the largest producers of natural diamonds globally.
With the advent of technology, today, lab-grown diamonds are also available in the market. These lab-grown diamonds have chemical and physical properties similar to natural diamonds. However, such diamonds may cost a little less than natural diamonds of the same size and quality.
In earlier times, there was no standard measure for assessing the quality of diamonds. The traders and jewellers used vague terms such as “water” and “river” to describe colourless diamonds and “Cape” for slightly yellowish diamonds. Similarly, a diamond’s cut quality was either considered “made well” or “made poorly”.
However, around the 1940s the concept of 4Cs was developed by the founders of GIA and gradually, it became the universally accepted method of assessing the quality of diamonds.
Let’s see what the 4Cs of diamonds are about.
The cut of a diamond is perhaps the most important in the 4Cs. It reflects how the diamond’s facets interact with light. This is determined by the various proportions, polish and overall symmetry of the diamond.
If a diamond is cut properly, it will exhibit maximum sparkle and brilliance. However, if it is cut poorly, it will seem to be dull even if it has high colour and clarity grade.
Diamond clarity refers to how pure and rare the stone is based on the visibility of certain characteristics under 10-power magnification. A diamonds’ clarity directly affects its sparkle. A diamond with a lower clarity grade would have many inclusions and because of this, it will look dull and sparkless.
The diamond clarity chart is as follows:
| FL, IF | Flawless and Internally Flawless | Eye clean |
| VVS1 and VVS2 | Very Very Slightly Included | Minute characteristics are visible on close inspection |
| VS1 and VS2 | Very Slightly Included | Minor characteristics are visible |
| SI1 and SI2 | Slightly Included | Characteristics are noticeable |
| I1, I2, I3 | Included | Characteristics are obvious |
Colour refers to the natural tint present in diamonds. Usually, almost all diamonds have a slight tint of yellow within them. However, the closer a diamond is to being colourless, the rarer and more precious it is.
The diamond colour chart is as follows:
| FL, IF | Flawless and Internally Flawless | Eye clean |
| VVS1 and VVS2 | Very Very Slightly Included | Minute characteristics are visible on close inspection |
| VS1 and VS2 | Very Slightly Included | Minor characteristics are visible |
| SI1 and SI2 | Slightly Included | Characteristics are noticeable |
| I1, I2, I3 | Included | Characteristics are obvious |
Carat refers to the weight of the diamond. Also, one carat of a diamond equals 0.20 grams. However, it must not be confused with the size of diamonds.
For instance, a diamond can have a higher carat weight without actually appearing larger. Similarly, two diamonds of the same carat weight can differ in size based on how deeply cut the one is.
For centuries diamonds have been a symbol of wealth and affluence in society. The world’s craze for diamonds is said to begin in India where diamonds were gathered from the country’s rivers and streams. As per some estimates, diamonds were traded in India around the 4th century BC. Usually, these yielded gemstones were limited and possessed by the creamy layer of Indian society. Gradually, Indian diamonds found their way into European markets where they were becoming a part of accessories of elites.
By the 1700s, India’s diamond supply began to decline and on the other hand, Brazil emerged as an important source of diamonds. Brazil went on to dominate the diamond market for more than one and a half centuries. As and when the sources of diamonds were changing, the diamond market was also experiencing a change. The ruling class- the elites- the major consumer of diamonds were on the decline due to the French Revolution which caused massive political upheaval in Europe.
The 1800s saw the emergence of western Europe and the US as the major diamond suppliers. Later on, explorers unearthed several precious diamonds from South Africa too. Today, Russia, Botswana, Canada, Democratic Republic of Congo, among others are the major suppliers of diamonds in the world.
Lab-grown diamonds are synthetic diamonds that are created in a laboratory setting. They are made of the same material as natural diamonds and have the same physical, chemical, and optical properties as mined diamonds. However, they are produced using advanced technology, such as high-pressure high-temperature (HPHT) or chemical vapor deposition (CVD), in a controlled environment.
Lab-grown diamonds have become increasingly popular as they offer a more ethical and environmentally friendly alternative to mined diamonds, while still providing the same stunning beauty and brilliance of natural diamonds. They are also often more affordable than mined diamonds, making them a popular choice for those looking for a budget-friendly option for diamond JEWELLERY.
As natural diamonds and lab-grown diamonds cannot be differentiated with naked eyes, be sure to get your lab-grown diamond report from SGL Labs.
The primary reason why diamonds are so expensive is due to their rarity and the time it takes to form a rough diamond. It takes hundreds, millions and sometimes even billions of years for diamonds to form in the Earth’s crust. Moreover, the process of mining them is time-consuming as well as resource driven. Additionally, around 50% of mined diamonds are not of suitable quality to be sold in the market. All these factors contribute to making diamonds an expensive purchase. Although treated diamonds cost a little less than flawless diamonds.
Apart from their elegance, durability and rarity; here are a few strong reasons for people’s love for diamonds –
