What Are Rectangle Engagement Rings?

A rectangle engagement ring (aka emerald-cut engagement ring) has an elongated, rectangular shape with eight sides and clipped corners. Throughout history, people have prized the emerald cut diamond engagement ring for its unique shape. An emerald cut diamond is also appealing because it can be set either horizontally or vertically.

Unlike the round diamond engagement ring that uses a brilliant style cut, the emerald cut diamond has step cuts. These step-cuts produce a stunning hall of mirrors-like effect within the diamond for maximum brilliance and sparkle.

How Does the Step Cut Differ from the Brilliant Cut?

Step cuts and brilliant cuts are quite similar when it comes to appearance. But there are some key differences between the two that make them ideal for different uses.

The main difference between a step and a brilliant cut is their symmetry. A step cut has slices that taper off at different angles; a brilliant cut has slices that taper off at the same angle. Therefore, in a step cut, you can see one side of the diamond engagement ring from a birds-eye view. Whereas in a brilliant cut you see multiple sides of the diamond from a birds-eye view.

You will typically find a step cut used in larger diamond engagement rings with smaller carat weights. This is because they help hide flaws in the stone’s surface or structure without sacrificing too much brilliance (or shine). These diamond engagement rings also tend to be less expensive than those with more facets. Why? Because they require less work on behalf of the cutter during production.

Emerald cut engagement rings are the most popular step-cut diamond shape. But there are many other different diamond shapes that also utilize the step-cut. These shapes include Asscher-cut diamonds and baguette-cut diamond engagement rings.

How Does an Emerald Cut Engagement Ring Differ From a Princess Cut Diamond Engagement Ring?

Princess cut diamonds are well-known for their brilliance and sparkle. Much like the emerald cut, princess cut diamonds are not round or oval and have four sides.

Unlike the emerald cut’s rectangular appearance, however, the princess cut has four equal sides and pointed edges. This, coupled with a brilliant cut, creates a completely different-looking engagement ring than the emerald cut diamond shape.

An Emerald Cut Diamond Engagement Ring Will Seem Larger

Thanks to the larger surface area of the emerald cut diamond, your engagement ring will seem larger than diamonds of similar carat weights or shapes.

Consider a one-carat round diamond engagement ring next to an emerald cut diamond engagement ring. When viewed from above, the emerald cut diamond will seem larger. This is because it has a larger face and table–despite being the same carat weight as the round diamond.

Emerald-Cut Engagement Rings Are More Affordable Than Other Brilliant Cut Diamonds

Due to the precision required by jewelers to create a brilliant cut, round diamonds and other similar brilliant cut engagement rings are generally more expensive.

Despite this, your step cut emerald diamond engagement ring will still be as radiant as a brilliant radiant cut diamond engagement ring.

Emerald Cut Engagement Rings Will Make Your Fingers Look Leaner and Longer

The emerald cut engagement rings rectangular shape draws the eye upward. As a result, the ring wearer’s finger appears longer and leaner. A square radiant cut diamond engagement ring cannot achieve this illusion.

Emerald Cut Engagement Rings Offer Exceptional Clarity

A diamond cut that utilizes steps offers an unobstructed view into the center of the emerald-cut diamond. This is a wonderful feature, particularly when you invest in a diamond that has a strong clarity rating. The clarity is greatly highlighted by the diamond shape.

What Are the Cons of an Emerald Cut Diamond Engagement Ring?

An Emerald Cut Diamond Engagement Ring Has Less Brilliance Than Other Diamond Shapes

An emerald-cut diamond is often thought to be less brilliant than other brilliant-cut diamond styles. They have the same number of facets as other shapes; however, their elongated shape equals more surface area and less depth. Therefore, they tend to reflect light in only one direction while other diamond cuts reflect light in many directions.

But don’t let that stop you from considering an emerald cut diamond shape for your engagement ring! The elongated shape creates a unique look that many people love. It also gives you more room for creativity when it comes to designing the setting around your stone.

An Emerald Cut Engagement Ring Won’t Hide Inclusions or Color Like a Brilliant Cut Diamond Shape Would

Thanks to the exceptional clarity of the emerald cut engagement ring, you can clearly see the interior of the diamond. This is great as long as you buy a highly-graded clarity and color diamond.

Alternatively, if you are just in the market for something unique, color and clarity may not mean as much to you. If you believe that beauty is truly in the eye of the beholder, your emerald cut engagement ring could provide a fascinating conversation starter in the world of diamond inclusions and color.

What Is the Best Setting for an Emerald Cut Engagement Ring?

When you’re ring shopping you need to know what setting will work best with the ring’s design. There are two setting types that work best with a rectangle engagement ring: prong and bezel.

Prong Setting

The prong setting is one of the most popular because it’s the easiest to set. It consists of four or six claws that hold the stone in place. Prongs are often used for expensive jewelry because they are easy to make.

Bezel Setting

A bezel setting is another popular option for an engagement ring. This is especially true when there is a lot of detail on the side of the stone. A bezel setting consists of a lip around all sides of the diamond that holds it securely in place. It also prevents any light from leaking out from underneath it.

What Is the Best Style for an Emerald-Cut Engagement Ring?

The Vintage Style Engagement Ring

An emerald cut diamond engagement ring already brings a modern classic appeal to an otherwise vintage stone shape. Why not highlight this vintage feel with a vintage band? The result combines stylish brilliance and fashion for an engagement ring that will blow your partner away.

What Is the Best Carat Weight for an Emerald Cut Engagement Ring?

The best carat weight for an emerald cut engagement ring depends on what you want out of your ring. If you want to make a statement, opt for a larger carat weight. But if you want something more understated, choose a smaller carat weight.

Regardless of how big or small your emerald cut is, make sure it fits your lifestyle and personality.

Can a Rectangular Diamond Shape Work in a Wedding Band?

Yes, a rectangular diamond shape can work in a wedding band just as well as in an engagement ring.

In fact, the same basic principles of good ring design apply to both. You want to ensure that your ring has enough metal for durability and comfort, but not so much that the ring becomes heavy or bulky. Make sure the stone is placed at an angle that makes it look its best—which means that some stones (like diamonds) will look better if they’re set diagonally rather than vertically.

Like considering the everyday wear of your engagement ring, it’s also important to consider how you’ll wear your wedding ring. If you’re going to be wearing it on a regular basis, then you’ll probably want something durable enough to withstand daily wear; if you plan on only wearing it sometimes (or only when going out), then you might not need such high-quality materials.
