What is a Diamond?

Diamonds are a type of gemstone with a lustrous, dark sheen. They are often used to represent value and wealth because they are very rare and durable. Diamonds come in many shapes and sizes, some as small as a pea or as big as an orange. They have been mined since ancient times, but it was not until the 1700s that a German scientist, Daniel Eulenstein, discovered how diamonds were created when he studied graphite ore.

Diamonds are the most famous gems and are the best way to show your love. The crystal called 'diamond' is formed from carbon atoms, with pure carbon being the hardest substance on earth. Growing the diamond is complicated and takes long periods of time. A single diamond can take up to 50 years to grow completely in size.

How to Tell if a Diamond Was Real or Not?

Real diamonds are often thought of as a luxury commodity. But in reality, diamonds are not all that expensive. The price of a diamond depends on the size, cut, clarity and colour of the diamond. Real Diamonds come from the earth and are mined from deep within the Earth’s crust.

What Does a Diamond Look Like?

The properties of diamonds are described in terms of four Cs: cut, colour, clarity, and carat. Diamonds with high crown qualities make them more valuable. A diamond's value also depends on the level at which they are found in the ground. A real diamond is usually made up of carbon atoms that are bonded into a molecular structure called a crystal lattice. The hardness and density of a diamond depend on the arrangement and strength of its molecular bonds. Diamonds can be classified into different categories according to these qualities.

Diamond Certificate of Authenticity

A Diamond Certificate of Authenticity (or COA) is a document created by an authorised retailer that confirms the genuineness of the diamond. While a Diamond Certificate of Authenticity is not legally required, it can help to protect the buyer from purchasing a fake diamond.

The certificate includes information such as the weight and cuts of the diamond, colour grade, certification number, country where it was sourced from and other identifying features. Some certificates will also include an appraisal telling you how much your diamond is worth.

Diamond Reflection Test

Diamonds are one of the most popular jewels that people buy. But there are many fake diamond sellers who offer a similar-looking product at a much lower price. So, how can you identify if the diamond is real or fake? One way is to perform the Diamond Reflection Test.

One of the simplest ways to check if a diamond is real or not is by performing the Diamond Reflection Test. This test requires you to hold a mirror close to your diamond and check for its reflection. If it has one face and two triangular faces, then it's probably genuine. But if it has one triangular face with two faces there, then it's not a real diamond.

Durability Test

Diamonds are expensive, and not everyone can afford them. That is why the question of whether a diamond is real or fake is one that many people have asked themselves. The truth is, it’s virtually impossible to tell the difference between a real diamond and a fake one unless you test their durability.

The hardness test will tell you if your diamond isn't real because this test measures how much pressure it takes for diamonds to chip or scratch another material, such as glass. A softer rock (such as limestone) will be scratched by harder materials (such as quartz) when under pressure.

Some Tips Before Buying a Diamond Jewellery

Shopping for Diamonds

A diamond is always in demand. But if you don't know how to buy one, then you can be taken for a ride and lose a lot of money. Here are some tips before buying diamonds or diamond jewellery:

  • Check if the jeweller is certified by GIA (Gemological Institute of America) and if they have the Diamond Mark.
  • Make sure that the diamond you are buying is worth its price tag. That means it should be in good condition, not chipped or scratched, and it should have high-quality clarity without any visible flaws from 10x magnification.
  • Consider your budget first before you go around looking at diamonds with an unrealistic budget in mind. There are plenty of other stones that can fulfil your needs at a much lower price than diamonds, like moissanite or cubic zirconia.
  • Find out about any hidden fees that might come up, like set-up fees and shipping costs.


Diamonds are one of the most popular jewellery items on the market today. They come in many shapes and sizes, and their colour can change depending on the light that hits them. Because they are so valuable, it is important to be careful when buying them. 

Make sure that you are well prepared and have read some tips or guidelines for identifying real diamonds. However, if you are still not sure if what you are buying is real, you can try checking out Astteria. They only offer legit jewellery with real gemstones!


What is the difference between a real diamond and a synthetic diamond?

A diamond is a mineral that is mined from the earth and captured in many colours, which are caused by impurities. It has long been used as an engagement ring to symbolise eternal love. With recent advances in science, there are now synthetic diamonds (man-made diamonds) that have indistinguishable properties from their mining counterparts.

The most common reason for this fraud is purely financial - synthetic diamonds are significantly cheaper than natural diamonds. One way to make sure that you are buying a real, mined diamond is if it's certified by a reputable company.

What is a fluorescence diamond?

Fluorescence diamonds are diamonds that emit fluorescent light. This results from fluorescence emissions and resonance in the diamond's crystal structure.

They are rarer than normal diamonds and can offer contrasting colours making them highly desirable. The process of inducing fluorescence in a diamond starts by using ultraviolet radiation to create "excited states" in the mineral. When these excited states decay, they release excess energy as light with a distinctive blue hue that causes the floats to glow blue or purple.

What are the 4Cs in Diamonds?

Diamonds are a very desired and expensive gemstone. Diamonds are graded on the 4C’s: colour, clarity, carat weight and cut.

Colour is the least important factor when evaluating diamonds, but it should still be taken into consideration. Clarity is how clear a diamond is; this can be described in terms of inclusions or blemishes that might impair the diamond’s beauty. Carat weight is the size of the diamond. Cut refers to how well-formed a diamond is when it has been cut for jewellery purposes.
