Lesson 2 - Clarity

If you're considering buying a 0.4 carat heart shaped diamond ring, the clarity of the diamond is the most crucial element to consider in terms of pricing.

⊗ Up to $1,114 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

Clarity is all about the flaws you can see in a diamond, but it's worth mentioning that most flaws are only visible with a 10x magnifying glass. Diamond clarity can be categorized as 'flawless' or 'included'. In between, you'll come across classifications like VS1, VS2, and SI1. These diamonds might have imperfections that can only be seen under 10x magnification. To the naked eye, they are typically invisible, so no one will notice them when they admire your ring!

Optimal Clarity Range for a 0.4 carat heart shaped diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 0.4 carat heart shaped diamond ring can result in significant savings, potentially reducing the total price by up to $1,114. While we highly recommend opting for a VS2 diamond due to its favorable price and clarity balance, it is important not to overlook SI1 diamonds. By investing a few minutes in sifting through the available options, you can easily find SI1 diamonds that appear virtually flawless for your heart shaped diamond ring.

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 heart-shaped diamond ring that weighs 0.4 carats, the diamond's color becomes an important factor in determining its price.

⊗ Up to $228 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can come in various shades, ranging from yellowish to completely colorless. The Gemological Institute of America (GIA) ranks diamonds on a scale from D (colorless) to Z (yellow or brown). Most jewelry diamonds have a slight amount of color and fall into the G-H category. These subtle color differences can only be detected when comparing them to higher-graded diamonds like D, E, or F. While larger diamonds tend to show color more noticeably, a heart-shaped diamond in the G-H category will still appear nearly colorless and will be less expensive than a D-grade diamond, which is completely colorless.

Optimal Color Range For A 0.4 Carat Heart Shaped Diamond Ring

Opting for the appropriate color grade when selecting a 0.4 carat heart-shaped diamond ring can lead to significant cost savings. Instead of paying premium prices for diamonds graded D-F, it is recommended to consider a diamond within the G-J range. By doing so, not only can you still obtain a breathtaking piece, but you can also save up to $228, in addition to any savings attained through wise decisions concerning clarity. In the case of more intricate designs, such as a halo diamond ring adorned with numerous smaller diamonds encircling the main stone, it is advisable to choose a central diamond falling within the G-H color range. This particular approach helps prevent any noticeable color contrast that may arise when comparing I-J graded diamonds to the smaller, typically 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 heart shaped diamond ring with the choice of 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.

If you ever decide to sell your heart-shaped diamond ring, choosing a lab-grown diamond can help minimize your financial loss.

Opting for the appropriate color grade when selecting a 0.4 carat heart-shaped diamond ring can lead to significant cost savings. Instead of paying premium prices for diamonds graded D-F, it is recommended to consider a diamond within the G-J range. By doing so, not only can you still obtain a breathtaking piece, but you can also save up to $228, in addition to any savings attained through wise decisions concerning clarity.

Lesson 5 - Carat / Size

Focus your money on carat weight when you are 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: The Perfect Choice for Your 0.4 carat heart shaped diamond ring.

You should check out diamonds that range from 0.36 to 0.44 carats. This will give you a good sense of the price differences without a significant change in size.

Lesson 6 - Cut

The way a diamond is cut directly affects its sparkle. For your 0.4 carat heart shaped diamond ring, make sure to choose either an ideal or excellent cut.

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

What is Cut?

If you want to find an absolutely stunning heart-shaped diamond ring that weighs 0.4 carats, it's all about the cut. The cut refers to how precisely and perfectly the diamond's facets have been shaped, and this is what ultimately affects its shine and sparkle.

The behind-the-scenes truth about diamonds

An "Ideal" cut diamond is the one that is perfectly proportioned to give off the most sparkle. People usually assume that it would be the most expensive. However, it's not always the case. Sometimes, a "Fair" cut diamond with the same carat, color, and clarity can actually cost more than an "Ideal" cut. It may seem confusing, but the reason behind it is that a poorly cut diamond often appears larger, but it lacks the brilliance and sparkle that you desire. Imagine a diamond without any sparkle - it's like a house without a solid foundation.

Here's a valuable tip: always opt for GIA Certified Excellent Cut Diamonds (also known as "Ideal" Cut).

Lesson 7 - Shape

The sparkliness of diamonds varies depending on their shape, and some shapes can add to the perceived value of a 0.4 carat heart shaped diamond ring.

What is Diamond Shape?

The shape of a diamond determines its style, like round, oval, or heart-shaped. Certain shapes can make a diamond appear bigger, while others provide a dazzling shine and a classic vibe. Take a look at our shape tool in this section to discover a wide range of 0.4 carat diamond rings with different shapes.

What shape to choose?

Yep, it's true that certain diamond shapes can give the stone a bigger look, and there are definitely some trendy shapes floating around. However, when it comes down to making a decision, concentrate on what really resonates with you and brings you the most joy. If you're not sure which shape to go for, a brilliant cut diamond could be a good choice. It includes Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant shapes. Round diamonds are classic and never go out of style, but you might discover that Oval and Marquise shapes create the illusion of a larger diamond for the same weight.

Lesson 8 - Setting

The band can drastically change the appearance of a 0.4 carat heart-shaped diamond ring.

What is setting?

The shiny part of the diamond ring, called the band, is what we call the setting. Usually, these are made of gold and come in different colors like white, yellow, or pink gold. You can also choose a band made of platinum. The setting is important in how the 0.4 carat heart-shaped diamond ring looks overall. This is your chance to show off your personal style. We've listed the three most popular settings for you. No matter which one you choose, it's always best to go with 14k gold. As you keep reading, you'll understand why.
The setting or band is really important for making your diamond look bigger and better. 

Make sure that the band of your ring is made of 14 karat gold.

Keep in mind this important rule. Avoid using 18k or 24k gold for your setting. Instead, go for 14k gold. Even though 18k and 24k gold have a higher purity, they are very soft and likely to bend. If the setting that holds your valuable diamond bends easily, there's a high chance that the diamond will fall out. This is a common problem faced by many people.

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

According to surveys, the majority of women prefer bigger diamonds. If you want to highlight the size of a 0.4 carat heart-shaped diamond ring, consider a Solitaire setting with a slim and delicate band. The difference between the thin band and the substantial diamond can create the impression of a larger gem. Including small accent diamonds along the band can add an elegant detail without taking attention away from the main diamond.

Halo: Enhance Your Diamond's Size with Small Diamonds

To make your 0.4 carat diamond ring with a heart-shaped stone look bigger, you might want to think about using a halo setting. The smaller diamonds around the main one make it look brighter and larger. If you want an even more dramatic effect, you could choose a double halo setting. When combined with a slender band, this can make a smaller diamond appear much larger and more extravagant in appearance.

Keep the focus on the main diamond.

Many women desire a diamond that looks impressive. A band that is overly ornate or wide could draw attention away from the diamond, making it appear smaller. If you want to show off your 0.4 carat heart-shaped diamond ring, it would be wise to choose a more straightforward band that doesn't overshadow the stone. However, if the overall ring design is more important to you, a band with intricate details may be a better choice. Just keep in mind that it might diminish the diamond's standout quality.
