This paragraph introduces a discussion on the popular diamond shapes. These shapes are widely recognized and sought after in the diamond industry due to their unique characteristics 

Each shape offers its own distinct features that make it worthy of consideration, such as the brilliance of the round cut and the exceptional sparkle of the princess cut. 

Round Cut

The round brilliant cut, renowned for its radiating brilliance and sparkling fire, remains the most favored shape among diamond enthusiasts. One of the biggest pros of this cut is that it is timeless. It is characterized by its rounded corners and perfectly symmetrical design, allowing light to reflect and refract within the stone, creating a stunning display of scintillation.

The round cut’s elongated shape (it’s not actually round) gives it a classic appearance with a modern twist, making it an ideal choice for those who desire both tradition and innovation in their diamond jewelry design. With its exceptional ability to showcase a diamond’s clarity and brilliance, the round cut continues to captivate hearts worldwide. You can’t go wrong with a round cut.

Up next is the princess cut, another popular diamond shape known for its exceptional brilliance and unique square or rectangular facets.

Princess Cut

The princess cut’s sharp corners and clean lines create a modern and sophisticated look that appeals to those seeking an elegant yet contemporary style. Its square rectangular shape emphasizes the diamond’s size, making it appear larger than other cuts of similar carat weight, making it great for smaller diamonds. Because it can have both rectangular and square facets the princess adds versatility to this already enchanting choice.

Emerald Cut

In contrast, to the princess cut, the Emerald cut isa diamond shape that showcases the original clarity of the stone through its rectangular facets. This unique cut combines clean lines that reminds one of an emerald with the brilliance typically associated with round diamonds. 

The Emerald cut is favored by those who desire a more understated elegance and appreciate a diamond’s natural clarity. An emerald cut should only be done on diamonds with high clarity because of this reason.

Diamond cutters carefully craft each Emerald-cut diamond to maximize its brilliance and fire, making it an excellent choice for those seeking a timeless and sophisticated look.

Oval Shape

Oval-shaped diamonds offer a twist on the classic cuts such as the round cut. This cut enhances the elegance of long and slender fingers while exuding an undeniable grace and charm.

The oval shape is great for those seeking a unique and sophisticated diamond cut. With its elongated silhouette and rounded edges, this shape creates a sense of symmetry and balance and is great for taller people with longer fingers and hands. 

It also maximizes the carat weight, making the diamond appear larger than it actually is.

Oval diamonds are known for their brilliant sparkle, similar to round diamonds but with a modern twist. They have become particularly sought after due to their ability to accentuate the wearer’s hand and create a soft and delicate look.

These two cuts share similarities in their ability to combine different shapes for a distinct aesthetic appeal.

Now that we have explored the characteristics of different diamond cuts, let us move on to discussing how one can choose the right shape for their desired jewelry piece without missing a step.

Diamonds in various shapes

How to Choose The Right Shape

Learning about 14 shapes can be overwhelming, and it’s not always easy to pick the right one for you. It’s ultimately down to personal preference, but one of the most important factors to look at in selecting a diamond and shape is the length to width ratio.

Why Length-to-Width Ratio Matters

The length-to-width ratio of a diamond is an important factor to consider because it can greatly impact the appearance and brilliance of the diamond. 

The ratio is simply calculated by dividing the length of the diamond by its width. This number has a significant effect on how the diamond looks on your finger.

For example, a higher length-to-width ratio creates an elongated diamond that  covers more of your finger, while a lower ratio will cover more of the band. 

Additionally, as you are now aware, different shapes have different ideal length-to-width ratios. Understanding this aspect can help you visualize how your engagement ring will look and ensure that it meets your personal preferences.

It’s worth noting that anything outside of the ideal range might negatively affect the brilliance and cut of the diamond.

Transitioning into the next section, let’s explore how diamond shape affects price…

How Diamond Shape Affects Price

The cost of a diamond is  greatly influenced by its shape, with round brilliant cut diamonds being the most expensive due to their popularity and the precision required in their manufacturing process.

Princess cut diamonds are slightly more affordable than round cut diamonds, as they use about 80% of the rough diamond.

On the other hand, fancy-shaped diamonds such as radiant, emerald, cushion, and asscher cuts are more affordable because they utilize most of the rough diamond and result in fewer discarded diamond chips. Typically, the more waste there is for a cut then more expensive it will be.

Measuring the size of the diamonds

These diamonds are created in a laboratory using advanced technology that replicates the conditions under which natural diamonds form.

Lab grown diamonds possess the same physical, chemical, and optical properties as natural diamonds, making them indistinguishable to the naked eye. Lab diamonds are real diamonds.

They can be cut into various shapes just like natural diamonds and often use the same cut & shapes as natural diamonds.
