The price of diamonds have surged by fifty percent in the last few years. Therefore, before investing in these metals, make sure that the jewelry has an IGI certification. IGI, i.e., International Gemological Institute, tests whether the diamond you are buying is authentic or not. The world’s famous diamond producers and jewelers get their diamonds certified from this certification organization.

In IGI, a diamond needs to go through 14 different types of tests, out of which four of them are based on carat, cut, color and clarity.

You need to be aware of the fact that there exist no reliable DIY tests to gauge the diamond’s authenticity. The best way to check its authenticity is by getting it checked by a gemologist or by checking its IGI certification.

Factor #2: The “4C” Theory:

When buying a diamond, it is essential to pay attention to the below mentioned 4 things which are jointly called 4C.


Diamonds have a light yellowish color and they are almost colorless. A good diamond is one whose color is faded. In this sense, the best diamond is a colorless one. According to the color of these metals, they are awarded different grades.

These grades lie in between ‘D’ to ‘V.’ The best grade is considered ‘D,’ that is given to colorless diamonds.


There are three types of cut: Propositional, Shallow, and Deep. Propositional cut diamonds are considered to be the most expensive ones.

Diamonds generally come in many sizes. Some of these famous shapes are – Marquis, Princess, Pear, Heart, round brilliant and Oval. Round brilliantly shaped ones are regarded as one of the best quality diamonds.


A diamond’s price and quality depends on its clarity to a large extent. The clarity of a diamond is divided into four categories such as IF, which stands for internally flawless, VS which stands for Very Slightly Inclusive and VVS  which means Very Very Slightly Inclusive.

Most diamonds are of VVS quality. IF quality ones have no marks or defects, so they are very high in demand and costly.


The size of the diamond is called carat. One carat diamond weighs 0.2 grams, and a 5 carat diamond weighs 1 gram.

Factor #4: Ask For A Guarantee card

After purchasing the diamond jewelry, ask for the purchase card and a guarantee card from the shopkeeper. However, the shopkeeper is not legally required to provide such a card with diamonds but some well-known jewelers give a guarantee card on their behalf. You can find the 4C detail of the diamond mentioned in this card. Based on this, customers can get an idea of every aspect of the jewelry they are purchasing.

When purchasing diamond jewelry, the inclusion of a guarantee card can significantly enhance buyer confidence. Esteemed jewelers, including different online retailers, often provide these cards, although they’re not mandated by law. A review Brilliant Earth provides and its approach reveals that their guarantee cards are particularly informative. These cards typically detail the 4C’s of the diamond – cut, color, clarity, and carat weight – offering buyers a transparent view of their investment.

You can exchange your old diamonds to buy a new one. By doing so, a certain amount of money is waived off, and then you need to pay for the rest of the price. Back in the day, people hesitated a little while buying diamonds due to a lack of guarantee of resale value. However, today many jewelers promise a 100% buyback policy in the market. Look for one that offers an exchange and buyback policy.

Factor #7: Compare The Diamonds

Now that you have selected two or more jewelries, compare them before buying one. Consider factors like which diamond appears more brilliant, which one has a lower price, and which one is more eye-clean. These factors will help you make an informed choice.

Also, you can choose not to buy mined diamonds. Instead, look for lab-made ones. Their popularity is growing exponentially, and while they have the same beauty as that of mined diamonds, lab-made ones cost you almost thirty percent less than the mined ones. However, if budget is not a constraint then you can choose to ignore these factors.
