Round-Shaped Diamonds

Everything you need to know about round-shaped diamonds

Are you planning to buy a diamond but don’t know from where to start? Diamonds are classy, elegant, and exquisite; they are the most precious and sought-after jewellery that everyone aspires to have. But it is not easy to buy the right diamond, especially if you’re shopping for it for the first time. 

What you need to know about round diamonds, and how to choose the right one

Many people buy a diamond based on its shine. However, not every shining diamond is worth the money you’re paying. 

There are many factors that you should consider when buying a diamond. These include colour, clarity grade, carat, and cut. Amongst all these, the cut is the most important factor you should consider when buying a diamond as it will determine its shine. Diamonds come in various shapes, and every shape is unique and exemplary. But, the most classic and expensive one is the round shape. 

Why are round diamonds so popular?

A round diamond is also known as a brilliant diamond. Brilliance determines how a diamond will shine. It is defined as the amount to white light a diamond reflects. The round shape is an ideal cut, having 58 facets. Due to this, rounded diamonds yield the maximum shine when compared to all other shapes.

Approximately 73% of all diamonds sold are round. With a brilliant cut, a round diamond showcases an incredible amount of fire. The ‘fire’ of a diamond is the amount of coloured light that it scatters.

Round diamonds have been in style for centuries and that’s not going to change, they’re an enduring classic.  With its 58 facets and elegance, it is the most expensive diamond. If you can afford to buy a round diamond, then it is the best bet to please your loved one; it is a shape that everyone cherishes.  

Round diamond cut quality

The round shape is the only shape that the GIA grades for cut. Check out this table to understand how GIA grades Round Brilliant Cuts:

L/W Ratio1.00-1.011.02>1.02

Apart from cut quality, don’t forget to check how deep the cut is. If they are too shallow, the light will pass through the sides without hitting the pavilion. As a result, the diamond won’t be able to yield the maximum sparkle at the table. On the other hand, in the case of deep cuts, the light exits through the bottom of the diamond as it strikes the pavilion at a sharp angle. In both cases, the diamond will sparkle less. In order to get the maximum fire and brilliance, make sure that the light strikes each pavilion and reflects back through the crown and table.

Round shape diamond colour

Today, the demand for coloured diamonds is increasing day by day. But it depends on individual choice. Many people love to have colourless diamonds, while others are interested in buying the diamonds that come with a special hue like pink, blue, yellow, or purple. If you’re looking to buy a pink colour round diamond, then its price will vary with supply and demand. The coloured diamonds with high colour grading will be less expensive compared to lower colour grade diamonds. Check out this table to evaluate the colour grading of round shaped diamonds.

Round shape diamond clarity grade

The clarity grade is another factor you need to consider when buying a round shape diamond. Clarity grade refers to the number of blemishes and inclusions present in a diamond. Since the assessment of clarity is done based on inclusions or surface flaws or blemishes, which can be observed through a microscope, which clarity grade you choose for a diamond solely depends on your personal choice.Though round diamonds are cut in a brilliant facet, the light is reflected from many angles which allows the inclusions to remain hidden. Hence, a round-shaped diamond does not need a very high clarity grade. However, in order to get the most out of your stone, it is crucial to determine if the diamond is eye-clean or not. Check out this table to understand which clarity grade is suitable for you:
 ExcellentVery GoodGoodFairPoor

How to buy the best round shaped diamond?

Apart from cut quality, colour, number of inclusions, it is essential to look for the location of inclusions. The reason behind it is that it is difficult to see the blemishes that rest on the perimeter through the diamond table. In this case, a lower clarity grade diamond can be just as beautiful as a higher clarity one.
