Lesson 2 - Clarity

The clarity of the diamond is the main aspect to consider when determining the price of a 0.4 carat marquise diamond ring.

⊗ Up to $780 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

Clarity is a word used to describe the imperfections in a diamond that can be seen. However, it's important to remember that these imperfections are usually only visible when you look at the diamond through a 10x magnifying glass. Diamond clarity ranges from "flawless" to "included". In between, you'll find classifications like VS1, VS2, and SI1. These diamonds may have imperfections that can only be seen with 10x magnification. To the naked eye, they look completely perfect, so nobody will be able to see any flaws when they admire your ring!

Optimal Clarity Range for a 0.4 carat marquise diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 0.4 carat marquise diamond ring can result in significant savings, potentially reducing the total price by as much as $780. When considering the clarity options, we strongly suggest opting for a VS2 diamond due to its favorable combination of price and clarity. However, it is important not to disregard SI1 diamonds. By dedicating just a few minutes to carefully examining different diamonds, you can easily find SI1 stones that appear nearly flawless.

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

The color of a diamond is another important factor in deciding the price of a 0.4 carat marquise diamond ring.

⊗ Up to $271 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 GIA grades them on a scale from D (colorless) to Z (yellow or brown). When it comes to jewelry, diamonds typically have a subtle color and fall within the G-H range. You can only really see these faint color differences when comparing them to higher grade diamonds like D, E, or F. The variation in color is more noticeable in larger diamonds. However, even a marquise diamond in the G-H range will appear almost colorless and be less costly than a completely colorless diamond, such as one with a D-grade.

Optimal Color Range For A 0.4 Carat Marquise Diamond Ring

Opting for the appropriate color grade for a 0.4 carat marquise diamond ring can lead to significant cost reductions. Instead of shelling out for high-priced D-F graded diamonds, contemplate selecting a diamond falling within the G-J range. This decision can still yield an exquisite piece while saving you up to $271 in addition to potential savings from shrewd choices concerning clarity. When it comes to more intricate designs like a halo diamond ring, adorned with numerous smaller diamonds encircling the main stone, it is advisable to opt for a central diamond falling within the G-H color range. This approach helps steer clear of any noticeable color contrast that may arise when comparing I-J graded diamonds to the smaller, generally colorless or near-colorless diamonds within 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 $700 on your 0.4 carat marquise diamond ring by opting for a lab grown diamond.

Lab-grown diamonds, made through artificial means, possess identical visual characteristics to their naturally occurring counterparts, yet they are produced in a manner that is more environmentally friendly and morally sound. Moreover, their enhanced accessibility offers a more economical option, as a lab-grown diamond can be up to 85% less expensive than a similar naturally formed diamond.

Opting for a lab-grown diamond when selling your 0.4 carat marquise diamond ring can reduce your financial loss.

Opting for the appropriate color grade for a 0.4 carat marquise diamond ring can lead to significant cost reductions. Instead of shelling out for high-priced D-F graded diamonds, contemplate selecting a diamond falling within the G-J range.

Lesson 5 - Carat / Size

Focus on the carat weight when you're shopping for a diamond ring.

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. 

This Carat Range is the Ideal Option for a 0.4 carat marquise 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 marquise 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?

The secret behind a remarkable 0.4 carat marquise diamond ring lies within the diamond's cut. It all boils down to the flawless and meticulous shaping of the diamond's facets, which directly impacts its overall shine and magnificence.

What diamond companies don't want you to know

In some cases, the belief that an 'Ideal' cut diamond, which is famous for its flawless sparkle, must always be the most expensive is not necessarily accurate. It's actually surprising that a 'Fair' cut diamond with the same carat, color, and clarity can sometimes cost even more. It may sound strange, but diamonds that are poorly cut can appear larger while lacking the desired sparkle and brilliance. It's like having a guitar without strings when you have a diamond without any sparkle.

Last but not least, make sure to go for GIA Certified Excellent Cut Diamonds (sometimes referred to as "Ideal" Cut).

Lesson 7 - Shape

Some diamond shapes are more sparkly & some make 0.4 carat marquise diamond rings look more expensive.

What is Diamond Shape?

The diamond shape showcases the unique style of the diamond, such as round, oval, or marquise. Certain shapes can give the illusion of a bigger diamond, while others add extra sparkle and a timeless, classic look. Take advantage of our shape tool in this section to explore a range of 0.4 carat diamond rings with various shapes.

What shape to choose?

Different diamond shapes can create the impression of being bigger, and some shapes are trendy at the moment. However, the main thing to focus on when making your choice is what makes you the happiest. If you're not sure, you might want to look into the brilliant cut diamond, which includes shapes like Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant. Among these options, Round diamonds are the most popular, but Oval and Marquise shapes can make the diamond look bigger even if it has the same carat weight.

Lesson 8 - Setting

The band has the ability to completely transform the appearance of a 0.4 carat marquise diamond ring.

What is setting?

Often referred to as the band, the setting is the metallic component of a diamond ring. Typically, it is made of gold and comes in white, yellow, or rose gold variations. Alternatively, you can opt for a platinum band. The setting greatly influences the overall appearance of your 0.4 carat marquise diamond ring. It provides an opportunity to showcase your individual style. We have gathered the three most favored settings for you. Regardless of your choice, it is recommended to go with 14k gold. Continue reading to discover the reasons behind this advice.
The setting or band is really important for making your diamond look bigger and better. 

It's always best to go with 14K Gold when selecting your ring band.

This is a really important rule to keep in mind. Avoid using 18k or 24k gold for your jewelry setting. Instead, go for 14k gold. It's important to mention that even though 18k and 24k gold are purer, they're much easier to bend and reshape. If the setting holding your precious diamond is too flexible, there's a much higher chance of the diamond falling out. It's a common problem that many people have experienced.

Solitaire Setting - A Slim Band Accentuates the Look of a Larger Diamond

Based on surveys, a significant number of women desire a large diamond. Elevate the visual appeal of a 0.4 carat marquise diamond ring by selecting a Solitaire setting with a thin and delicate band. The difference between the dainty band and the impressive diamond can create the illusion of a bigger gem. To enhance the ring further, consider settings that incorporate small accent diamonds along the band, enhancing its attractiveness without diverting attention from the main diamond.

Halo: Boost Your Diamond's Volume with Many Small Gems

Looking to make your 0.4 carat marquise diamond ring appear larger? A halo setting could be the solution. This type of setting features smaller diamonds surrounding the main gem, which creates a stunning effect and gives the illusion of a bigger diamond. For an even more impressive look, consider a double halo setting. When combined with a slim band, it can make a smaller diamond appear much larger, adding a touch of extravagance to your ring.

Maintain the Main Diamond's Dominance

Many women desire a diamond that looks big and impressive. A band that is overly decorative or wide might take away attention from the diamond, making it seem smaller. If you want to showcase your 0.4 carat marquise diamond ring, a plain band would be a good option. However, if you value the overall design of the entire ring, a more detailed band might be the right choice for you. Just remember, this could diminish the diamond's standout quality.
