A diamond shape is simply the outline of the diamond as it looks from top to bottom. The popular shapes of diamonds are round, emerald, oval diamond, pear shape diamond, heart-shaped, and so on. You may be already familiar with the shape of a diamond (like a square shape, rectangular shape, etc. ) but not aware of its technical name. 

But, why is the shape important? Imagine you bought the least expensive diamond cut with a large face-up area but it doesn’t add much to the overall appeal of the ring. On the contrary, a perfect shape can enhance the appeal of the diamond and magnify the radiance of your ring! 

So, what factors to consider while selecting a perfect diamond shape? Though there isn’t any hard and fast rule, you can consider the shape with a heart capturing spark, or the shape of your partner’s finger, or on a more practical note, your budget. 


In simple terms, diamond-cut exhibits the symmetrical design, proportions, polish, and design of the diamond. The ‘Cut’ of a diamond is a part of the 4'cs diamond (used for assessing the quality of a diamond) along with Carat, Clarity, and Colour. 

There are a variety of cuts of diamonds from which you can choose such as cushion-cut diamonds, emerald-cut diamonds, fancy-cut diamonds, pear cut, Trillion-cut diamonds,radiant-cut diamonds, marquise-cut diamonds, oval-cut diamonds, heart shape diamonds, etc.

But, why is the cut important? The cut determines the degree of sparkle and ultimately the overall brilliance of the diamond! 

The SGL Labs assigns a diamond cut grade by considering several factors on a scale of poor to excellent. Usually, very good and excellent are the desired diamond cut grades.
