Lesson 2 - Clarity

If you're in the market for a 0.4 carat oval diamond ring, remember that the diamond's clarity is the main determinant of its price.

⊗ Up to $729 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

In America, clarity refers to the presence of noticeable flaws in a diamond. But it's important to note that these flaws are usually only visible when using a 10x magnifying glass. Diamond clarity is categorized from 'flawless' to 'included'. In between, there are classifications like VS1, VS2, and SI1. These diamonds may have flaws that can only be seen with 10x magnification. To the naked eye, they look completely clear, so nobody will notice any imperfections when they admire your ring!

Optimal Clarity Range for a 0.4 carat oval diamond ring

Choosing a diamond from the VS2-SI1 clarity range for your 0.4 carat oval diamond ring can result in significant savings, potentially reducing the total price by up to $729. In terms of price and clarity, we strongly suggest considering the VS2 option. However, it is important not to dismiss SI1 diamonds entirely. With just a few minutes of searching through the available diamonds, you can find ones that exhibit a nearly 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

The cost of a 0.4 carat oval diamond ring is greatly affected by the color of the diamond you choose.

⊗ Up to $265 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamond color is determined by the presence or absence of a yellow hue. The GIA rates diamond color on a scale from D (no color) to Z (light yellow or brown). When it comes to making jewelry, diamonds that are close to colorless, falling within the G-H range, are typically used. It can be difficult to spot any minor traces of color in these diamonds unless they are compared to higher-graded ones. It's important to note that the differences in diamond color are usually extremely subtle and may go unnoticed by someone without training. However, in larger diamonds, the color may become more noticeable. A diamond within the G-H range, which is almost colorless, will appear that way and be priced more favorably compared to diamonds that are more colorless.

Optimal Color Range For A 0.4 Carat Oval Diamond Ring

Choosing the appropriate color grade for a 0.4 carat oval diamond ring can lead to significant cost reductions. Instead of paying premium prices for diamonds graded D-F, it is recommended to opt for a diamond within the G-J range. By doing so, you can still obtain a breathtaking piece while potentially saving up to $265, in addition to any savings made through smart decisions regarding clarity.

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 $600 on your 0.4 carat oval diamond ring by opting for a lab grown diamond.

Lab-grown diamonds are appealing because they look just like natural diamonds, even though they are made in a lab. What makes them even better is that they are produced in a more sustainable and ethical way. Plus, they are way more affordable than natural diamonds, with a lab-grown diamond costing up to 85% less.

If you ever plan to sell your 0.4 carat oval diamond ring, choosing a lab-grown diamond can help reduce your financial loss.

Choosing the appropriate color grade for a 0.4 carat oval diamond ring can lead to significant cost reductions. Instead of paying premium prices for diamonds graded D-F, it is recommended to opt for a diamond within the G-J range.

Lesson 5 - Carat / Size

When you're shopping for your diamond ring, make sure to consider the carat weight.

Why is Carat Important?

Picture a diamond ring. The size of the central diamond really catches your attention, doesn't it? Well, surveys indicate that women concur - it's the most crucial aspect. The higher the carat, the larger the diamond, and that's where we suggest you invest your funds.
Watch us compare sizes and help you visualize what you want. 

If you're looking for a 0.4 carat oval diamond ring, choose from this range of carats.

We recommend checking out diamonds that range from 0.36 to 0.44 carats. This will give you a variety of prices without a significant increase in size.

Lesson 6 - Cut

Always consider the cut of the diamond as it determines its sparkle. When buying your 0.4 carat oval diamond ring, go for an ideal or excellent cut.

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

What is Cut?

When it comes to a superb 0.4 carat oval diamond ring, the cut takes the prize. The way the diamond's facets are shaped and aligned can greatly boost its shine and beauty.

A hidden truth within the diamond industry

You'd probably assume that a diamond with an 'Ideal' cut, famous for its flawless sparkle, is always the most expensive choice. However, the truth is that there are situations where a 'Fair' cut diamond, with the same carat, color, and clarity, can be pricier. It may sound strange, but diamonds that are poorly cut can appear larger while lacking the desired sparkle and brilliance. A diamond without any sparkle is akin to a smartphone without a battery.

Keep this in mind: go for GIA Certified Excellent Cut Diamonds (sometimes referred to 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 oval diamond ring.

What is Diamond Shape?

The diamond shape symbolizes the style of the diamond, such as round, oval, or other shapes. Certain shapes can give the illusion of a bigger diamond, while others add more sparkle and a timeless, classic look. Check out the shape tool in this section to explore various 0.4 carat diamond rings with different shapes.

What shape to choose?

Sure, some diamond shapes can make the stone look bigger, and some shapes are popular right now. But remember, what really counts is what makes you the happiest. If you're not sure, a brilliant cut diamond, such as Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant shapes, might be your best bet. Out of these, Round diamonds are the most popular, while Oval and Marquise shapes can give the impression of a larger diamond without weighing more.

Lesson 8 - Setting

The band can greatly change the way a 0.4 carat oval diamond ring looks.

What is setting?

The metal part of a diamond ring, often called the band, is called the setting. They are usually made from gold and come in various colors like white, yellow, or rose. You can also choose a platinum band if you like. The setting plays a crucial role in the overall look of your 0.4 carat oval diamond ring. It allows you to showcase your personal style. Here are the three most popular settings to consider. Regardless of your choice, we suggest sticking with 14k gold. We'll explain why as you continue reading.
The setting or band is really important for making your diamond look bigger and better. 

If you're looking for the best option, go with a 14K gold band.

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 Thinner Band to Make the Diamond Look Larger

In surveys, the majority of women tend to desire a big diamond. To make a 0.4 carat oval diamond ring appear larger visually, consider using a Solitaire setting with a slim and sophisticated band. The difference between the modest band and the sizable diamond can create the illusion of a bigger stone. Additional accent diamonds along the band can further emphasize this effect, adding a touch of charm without taking away from the main diamond.

Halo: Make Your Diamond Look Bigger with a Bunch of Smaller Stones

To make your 0.4 carat oval diamond ring stand out, you might want to think about using a halo setting. This technique involves using smaller diamonds to encircle the main stone, which enhances its sparkle and creates the illusion of a bigger diamond. If you really want to amplify this effect, you can opt for a double halo setting. When combined with a slender band, this setting can make even a tiny diamond appear much larger, giving the impression of a more lavish piece of jewelry.

The main diamond should be the focal point.

Many women prefer a diamond that appears big and noticeable. If the band of the ring is too extravagant or wide, it might take away from the diamond, making it seem smaller. If you want your 0.4 carat oval diamond ring to be the main focus, it would be smart to choose a simple and unobtrusive band. However, if you care more about the overall look of the ring, a fancy band might be your top choice. Just be aware that this could make the diamond less prominent.
