Lesson 2 - Clarity

When shopping for a 0.3 carat radiant cut diamond ring, the diamond's clarity is the primary pricing factor to keep in mind.

⊗ Up to $44,577 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

When we talk about clarity, we're basically talking about any imperfections in a diamond. However, it's important to emphasize that most of these flaws can only be seen when the diamond is magnified 10 times. The terms "Flawless" (FL) and "included" (I) are used to describe the range of diamond clarity. But you'll also come across terms like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included). These grades indicate that there may be some defects in the diamond, but they can only be seen with a 10x magnifying glass. To the naked eye, these diamonds usually look perfect, so no one will notice any flaws when they admire your ring!

Optimal Clarity Range for a 4 carat cushion cut diamond ring

Choosing a diamond within the VS2-SI1 clarity range for a 4 carat cushion cut diamond ring can result in significant savings, possibly reducing the total price by up to $44,577. For the best balance between price and clarity, we strongly suggest considering diamonds in the VS2 category. However, it is crucial not to disregard SI1 diamonds, as with a brief search through available options, you can uncover diamonds that exhibit 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

The cost of a 4 carat cushion cut diamond ring is greatly impacted by the color of the diamond you select.

⊗ Up to $20,119 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can range in color from slightly yellowish to completely colorless. The Gemological Institute of America (GIA) rates diamonds on a scale from D (no color) to Z (yellow or brown). When it comes to jewelry, diamonds typically have a slight amount of color and fall within the G-H range. The subtle hints of color in these diamonds can only be detected when compared to higher grade diamonds like D, E, or F. While the color is less noticeable in smaller diamonds, in larger ones like a cushion cut within the G-H range, it will still appear nearly colorless. Additionally, diamonds in the G-H range are generally less expensive than those with a D-grade, which are completely colorless.

Optimal Color Range For A 4 Carat Cushion Cut Diamond Ring

When selecting a 4 carat cushion cut diamond ring, opting for a diamond in the F-H color range can lead to considerable savings. By avoiding the higher price tags associated with D-E graded diamonds, you can still obtain a breathtaking piece while potentially saving up to $20,119, in addition to any savings from smart choices regarding clarity.

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

Save up to $53,000 on your 4 carat cushion 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.

If you ever decide to sell your 4 carat cushion cut diamond ring, choosing a lab-grown diamond can help minimize your financial loss.

When selecting a 4 carat cushion cut diamond ring, opting for a diamond in the F-H color range can lead to considerable savings.

Lesson 5 - Carat / Size

Invest more in carat size for a bigger gem in your diamond ring.

Why is Carat Important?

Imagine a diamond ring. What's the most eye-catching aspect? Well, it's definitely the size of that dazzling diamond in the middle. When ladies are asked about their preferences, the number one priority is the size of the main diamond. Therefore, we recommend investing your budget in the carat weight, as it determines the diamond's size.
Watch us compare sizes and help you visualize what you want. 

When you're shopping for a 4-carat cushion cut diamond ring, consider choosing from this range of carats.

We recommend looking at diamonds that range from 3.6 to 4.4 carats. This way, you can explore different prices without a significant increase in size.

Lesson 6 - Cut

Don't underestimate the importance of the cut when it comes to a diamond's sparkle. Ensure you choose an ideal or excellent cut for your 4 carat cushion cut diamond ring.

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

What is Cut?

If you're on the lookout for the most stunning 4 carat cushion cut diamond ring, keep in mind that the way it's cut plays a crucial role in its sparkle and brilliance. The cut specifically refers to how accurately and flawlessly the diamond's angles are shaped.

The behind-the-scenes truth about diamonds

You might think that an 'Ideal' cut diamond, which is crafted to make it sparkle the most by having perfect proportions, would be the priciest one. However, that's not always true. Sometimes, a 'Fair' cut diamond with similar carat, color, and clarity can actually be more expensive. It might seem a bit confusing, but poorly cut diamonds can actually look bigger while lacking the sparkle and brilliance that you want. A diamond without sparkle is like a phone without any signal.

Keep this in mind: go for GIA Certified Excellent Cut Diamonds (sometimes referred to as "Ideal" Cut).

Lesson 7 - Shape

Diamonds come in many shapes, each with its own sparkle factor, Some of which can give the impression of a higher-priced 4 carat cushion cut diamond ring.

What is Diamond Shape?

When we mention the diamond shape, we're talking about the way the diamond looks, such as being round, oval, or cushion-shaped. There are actually many other shapes out there too. Certain shapes can make the diamond seem larger, while others give it more sparkle and a classic appearance. Take a look at our shape tool in this section, where you can explore a range of 4 carat diamond rings available in 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 really change the appearance of a 4 carat cushion cut diamond ring.

What is setting?

The shiny part of a diamond ring, sometimes called the circle, is known as the setting. Usually, it's made of gold and comes in different colors like white, yellow, or pink gold. Another option is a band made of platinum. The setting plays a big part in how your 4 carat cushion cut diamond ring looks overall. It gives you a chance to show off your own personal style. Here, we've listed the top three settings that are really popular right now. No matter which one you choose, it's a good idea to go with 14k gold. As you keep reading, you'll find out why.
The setting or band is really important for making your diamond look bigger and better. 

Choose a 14K gold band.

Here's an important rule to remember. Avoid using 18k or 24k gold for your jewelry setting. Instead, go for 14k gold. Even though 18k and 24k gold are purer, they are much softer and more prone to bending. If the band holding your precious diamond bends easily, there is a much higher risk of the diamond falling off. This is a problem that many people commonly experience.

Solitaire Ring - A Thin Band Makes Your Diamond Appear Bigger.

Based on survey data, many women aspire to have a large diamond. To maximize the apparent size of a 4 carat cushion cut diamond ring, consider a Solitaire setting with a slim, refined band. The contrast of the smaller band with the larger diamond can make the stone appear larger. To augment this effect, look for settings that feature small accent diamonds along the band. They'll add a tasteful embellishment without taking attention away from the main diamond.

Halo: Increase the size of your diamond by surrounding it with tiny gems.

To make your 4 carat cushion cut diamond ring look even more stunning, you should think about getting a halo setting. This technique involves using smaller diamonds to encircle the main stone, which will make it shine brighter and appear bigger. If you really want to amp up this effect, go for a double halo setting. Combined with a slim band, this setting can make even a tiny diamond look much larger, giving off a luxurious vibe overall.

The main diamond needs to stay the focal point.

Many women prefer a diamond that looks big. A band that is too detailed or wide might take away attention from the diamond, making it appear smaller. If you want your 4 carat cushion cut diamond ring to stand out, you may want to pick a simpler band that doesn't overpower it. However, if the overall design of the ring matters more to you, a more decorative band might be your preference, but remember, it could make the diamond less noticeable.
