Choosing your diamond wisely: what criteria should you consider?

Would you like to purchase a diamond, but lack experience and don't know how to choose? Follow our expert gemologists' advice to understand the criteria to base your diamond purchase on.

Does choosing a diamond on impulse work?

First, it is often said that to buy a diamond or any stone or piece of jewelry, you should be guided by your heart's desire. This is true, but that initial attraction is not the only criterion to consider! It is also important to take into account the diamond's quality, especially if you plan to resell it in the future. Choosing a diamond thus involves a subjective aspect (everyone has a different vision of what a "beautiful" diamond is), but it still requires some careful thought.

A diamond's quality is mainly determined by what is known as the 4Cs:

• Carat (the weight of the diamond in carats)
• Color (whether the diamond leans more towards white or yellow)
• Clarity (the degree of purity of the diamond)
• Cut (the quality of the diamond's cut)

You will find the diamond's ratings on these 4 criteria on its certificate of authenticity, usually issued by one of the world's main gemological laboratories: IGI, GIA, HRD...

Generally, one will choose mainly based on the diamond's weight, as it is the factor that most influences the stone's selling price. However, the diamond's weight must be weighed against the other criteria to make a good choice. Indeed, for a diamond to be "beautiful," it must shine optimally. Criteria beyond the 4Cs come into play and determine how the diamond shines:

• The diamond's shape: even though the most classic diamond is the round brilliant cut, there are multiple diamond shapes, and each person will choose based on their tastes and preferences: cushion, princess, oval...
• Fluorescence: a fluorescent diamond will appear bluish under UV light;
• Symmetry;
• Polish.

How to choose a beautiful, brilliant diamond on a reduced budget?

A good-quality diamond with optimal brilliance will meet the following criteria:

• A Round brilliant cut or, for a lesser budget, an Oval or Cushion cut;
• A cut quality rated Excellent or Very Good;
• A color between D and H (after H, the diamond will lean towards yellow);
• A clarity ranging between SI1 and VS (or, if your budget allows, VVS or even IF), ensuring a minimum of visible inclusions on your diamond. Beware that some diamond shapes, such as the Princess cut, require a clarity rated at least VS, as inclusions tend to be more visible;
• Low or no fluorescence.
