Lesson 2 - Clarity

The price of a 0.4 carat emerald cut diamond ring is heavily dependent on the clarity of the diamond.

⊗ Up to $1,221 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

In the world of diamonds, clarity refers to how flawless they are. However, the interesting part is that these flaws are only visible under a 10x magnifier. The clarity scale ranges from 'flawless' to 'included', with classifications like VS1, VS2, and SI1 in between. Diamonds in these categories usually have imperfections that can only be seen with magnification. So, to the naked eye, they look completely clear, and nobody will notice any flaws when they admire your ring!

Optimal Clarity Range for a 0.4 carat emerald cut diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 0.4 carat emerald cut diamond ring can result in significant savings, potentially reducing the total price by up to $1,221. When considering the balance between price and clarity, we highly recommend opting for a VS2 diamond. However, it is important not to disregard SI1 diamonds. By dedicating a few minutes to sift through the available diamonds, you may be able to discover ones that possess an almost flawless appearance.

One more important tip! Always avoid "cloudy"

This one is simple. Always avoid cloudy diamonds found in the GIA certificate. This is the one flaw that really matters for brilliance.

Lesson 3 - Color

When shopping for a 0.4 carat emerald cut diamond ring, the diamond's color plays a vital role in determining its price.

⊗ Up to $209 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can have a slight yellow tint or be completely colorless. The Gemological Institute of America (GIA) categorizes them on a scale from D (no color) to Z (yellow or brown). Most diamonds used in jewelry have a small amount of color, falling within the G-H range. Any faint traces of color can only be noticed when compared to higher-grade diamonds like D, E, or F. While larger diamonds may show more noticeable color, an emerald diamond in the G-H range will still appear almost colorless and cost less than a D-grade diamond, which is completely colorless.

Optimal Color Range For A 0.4 Carat Emerald Cut Diamond Ring

Choosing the right color grade for a 0.4 carat emerald cut diamond ring can result in significant savings. Instead of paying premium prices for D-F graded diamonds, consider opting for a diamond in the G-J range. This decision can still yield a striking piece while saving you up to $209, in addition to any savings from making informed choices regarding clarity. When it comes to more intricate designs like a halo diamond ring with numerous smaller diamonds encircling the main stone, it is advisable to select a central diamond in the G-H color range. This approach helps prevent any noticeable color contrast that may arise with I-J graded diamonds when compared to the smaller, usually colorless or near-colorless diamonds in the halo.

Lab Grown Diamonds

Lab grown diamonds can often cut prices in half and no one will ever notice the difference. 

Lesson 4 - Lab Grown
Save up to 85% on your diamond ring.

Save up to $500 on your 0.4 carat emerald cut diamond ring by opting for a lab grown diamond.

Lab-grown diamonds, also referred to as man-made diamonds, offer the benefit of having the same appearance as natural diamonds, but they are produced in a way that is more environmentally friendly and morally conscious. Moreover, lab-grown diamonds are more easily accessible compared to natural diamonds, resulting in much more affordable prices. In fact, a lab-grown diamond can be as much as 85% less expensive than a similar natural diamond.

Choosing a lab-grown diamond for your 0.4 carat emerald cut ring can mitigate your financial loss when it comes time to sell.

Choosing the right color grade for a 0.4 carat emerald cut diamond ring can result in significant savings. Instead of paying premium prices for D-F graded diamonds, consider opting for a diamond in the G-J range. This decision can still yield a striking piece while saving you up to $209, in addition to any savings from making informed choices regarding clarity. When it comes to more intricate designs like a halo diamond ring with numerous smaller diamonds encircling the main stone, it is advisable to select a central diamond in the G-H color range.

Lesson 5 - Carat / Size

When searching for a diamond ring, prioritize the carat weight as the main factor to consider when deciding where to allocate your budget.

Why is Carat Important?

Take a moment to consider a diamond ring. The first thing that catches your eye is the size of the sparkling center diamond, isn't it? Well, for women, it's the same thing. They prioritize size above anything else. That's why when it comes to carat weight, which directly affects the size of the diamond, we suggest, "That's where you should allocate your budget!"
Watch us compare sizes and help you visualize what you want. 

Use this carat range as a guide for a 0.4 carat emerald cut diamond ring.

It would be a great idea to check out diamonds between 0.36 and 0.44 carats. This will help you understand the various price ranges without a significant change in size.

Lesson 6 - Cut

When purchasing your 0.4 carat emerald cut diamond ring, keep in mind that the cut of the diamond determines its sparkle and shine. Opt for an ideal or excellent cut to enhance its beauty.

Find out why cut makes diamonds sparkle and why you want ideal or excellent cut diamonds.

What is Cut?

If you want to discover an absolutely breathtaking emerald cut diamond ring that weighs 0.4 carats, you have to focus on its cut. That means you need to consider how precisely and perfectly the diamond's facets have been shaped, as it directly impacts the ring's overall brilliance and radiance.

The behind-the-scenes truth about diamonds

You might think that an 'Ideal' cut diamond, which is crafted to give maximum sparkle by having perfect proportions, would be the priciest option. However, that is not always true. Sometimes, a 'Fair' cut diamond with similar carat, color, and clarity can have a higher price tag. It may seem confusing, but diamonds that are poorly cut can actually look bigger while lacking the desired sparkle and brilliance. A diamond without sparkle is comparable to a phone with no signal.

Don't forget this important tip: always select GIA Certified Excellent Cut Diamonds (often referred to as "Ideal" Cut).

Lesson 7 - Shape

The level of sparkle in diamonds depends on their shape, and some shapes can create the impression of a pricier 0.4 carat emerald cut diamond ring.

What is Diamond Shape?

The diamond's style is determined by its shape, such as being round, oval, or emerald. Different shapes can make the diamond appear bigger or enhance its sparkle and timeless beauty. In this section, you can explore an assortment of 0.4 carat diamond rings with various shapes using our shape tool.

What shape to choose?

Sure, some diamond shapes can make the stone look bigger, and some shapes are currently trendy. But the most important thing is to choose what you love and makes you happy. If you're not sure about your preference, think about getting a brilliant cut diamond. It includes Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant shapes. Among these, Round diamonds are the most popular, but Oval and Marquise shapes can make the diamond look bigger even with the same carat weight.

Lesson 8 - Setting

The band greatly impacts the overall appearance of a 0.4 carat emerald cut diamond ring.

What is setting?

The part of a diamond ring that holds the stone is called the setting. It is usually made of gold in different colors like white, yellow, or rose. Another choice is a platinum setting. The setting is important in creating the overall appearance of your diamond ring with a 0.4 carat emerald cut stone. It allows you to showcase your personal style. Below, we have described the three most popular settings. Regardless of your preference, it is recommended to choose 14k gold. Continue reading to find out why.
The setting or band is really important for making your diamond look bigger and better. 

Think about getting a 14K gold band for your ring.

Always keep in mind this important advice. Avoid choosing 18k or 24k gold for your setting. Opt for 14k gold instead. Even though 18k and 24k gold are more pure, they are much softer and more prone to bending. If the setting that holds your precious diamond bends, there is a higher chance of the diamond coming loose and falling out. This is a problem that is commonly encountered.

Solitaire - A Delicate Ring Enhances the Size of the Center Diamond Significantly

According to polls, a lot of women desire a big diamond. Make a 0.4 carat emerald cut diamond ring with a Solitaire setting that has a thin, delicate band to make it look even more visually stunning. The difference between the smaller band and the impressive diamond can give the illusion of a bigger stone. To add more appeal, choose settings that have small accent diamonds on the band, enhancing the ring's beauty without distracting from the main diamond.

Halo: Make Diamond Look Bigger with Lots of Smaller Diamonds

To give your 0.4 carat emerald cut diamond ring a bigger appearance, you might want to think about using a halo setting. The smaller diamonds surrounding the main stone make it look brighter and appear larger. For a more striking visual trick, you could choose a double halo setting. When combined with a slender band, this can turn a smaller diamond into a lavish gem that seems much larger.

Don't diminish the significance of the main diamond.

Most women prefer their diamond to look big. A fancy or wide band might take away from the diamond, giving the illusion of it being smaller. If you want your 0.4 carat emerald cut diamond ring to be the center of attention, a simpler band would be a good option. However, if you value the overall design of the ring more, a more intricate band might be the way to go, but keep in mind that this may take away from the diamond's standout look.
