Lesson 2 - Clarity

When looking to purchase a 0.33 carat oval diamond ring, keep in mind that the clarity of the diamond is the biggest influencer of its cost.

⊗ Up to $91,580 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 in diamonds, we're basically talking about how visible the flaws are. But it's important to note that most flaws can only be seen with a 10x magnifying glass. Diamond clarity goes from 'flawless' to 'included'. In the middle, you'll find classifications like VS1, VS2, and SI1. These diamonds might 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 4 carat radiant cut diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 4 carat radiant cut diamond ring can result in significant savings, potentially reducing the total price by up to $91,580. We strongly suggest considering the VS2 clarity grade due to its favorable balance between price and clarity. However, it is important not to dismiss SI1 diamonds entirely - with a brief search through available options, you can find diamonds 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

The color of the diamond has a significant impact on the price of a 4 carat radiant cut diamond ring.

⊗ Up to $29,698 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can come in different shades, ranging from slightly yellowish to completely clear. The Gemological Institute of America (GIA) rates them on a scale from D (no color) to Z (yellow or brown). When it comes to jewelry, diamonds usually have a slight hint of color and fall within the G-H range. The subtle traces of color in these diamonds can only be detected when compared to higher-grade ones like D, E, or F. While smaller diamonds may not show as much color, larger ones in the G-H range, like a radiant cut, will still appear almost colorless. Additionally, they will be less expensive than a D-grade diamond, which is completely colorless.

Optimal Color Range For A 4 Carat Radiant Cut Diamond Ring

Opting for the appropriate color grade for a 4 carat radiant cut diamond ring can lead to significant cost reductions. Rather than shelling out a fortune for diamonds graded D-F, consider selecting a diamond within the G-J spectrum. By doing so, you can still obtain an exquisite piece while pocketing potential savings of up to $29,698, in addition to any other savvy choices made regarding clarity.

Lesson 5 - Carat / Size

When you're shopping for a diamond ring, prioritize investing in the carat weight.

Why is Carat Important?

The first thing everyone thinks about when it comes to a diamond ring is the size of the main diamond in the center. In fact, when women are asked, the most important aspect of the ring to them is the size of the center diamond. The carat weight directly affects how big the diamond appears, so we suggest allocating most of your budget towards this.
Watch us compare sizes and help you visualize what you want. 

Choose this carat range for shopping for a 4 carat radiant cut diamond ring.

It's a good idea to check out diamonds between 3.6 to 4.4 carats. This way, you can get an idea of the various price ranges without a significant change in size.

Lesson 6 - Cut

The sparkle of a diamond is determined by its cut. Ensure you opt for an ideal or excellent cut when purchasing your 4 carat radiant cut diamond ring.

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

What is Cut?

When you're on the lookout for a stunning 4 carat radiant cut diamond ring, the way it's cut plays a crucial role. The cut determines how precisely the diamond's angles are shaped, which ultimately affects the ring's sparkle and brilliance.

The undisclosed secret of diamond companies

You might think that the most expensive diamond is always the one with the perfect cut, known as the 'Ideal' cut. But surprisingly, there are cases where a diamond with a 'Fair' cut can be pricier, even if it has the same carat, color, and clarity. It may sound strange, but diamonds that are poorly cut can appear larger while lacking the sparkle and brilliance you're looking for. A diamond without sparkle is like a kite without a string.

Keep this in mind: go for GIA Certified Excellent Cut Diamonds (sometimes 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 4 carat radiant cut diamond ring.

What is Diamond Shape?

The diamond shape is all about the style of the diamond itself. You can find various shapes like round, oval, radiant, and many others. Different shapes can give the illusion of a bigger diamond or offer more sparkle and classic charm. Check out our shape tool in this section to see a wide range of 4 carat diamond rings featuring different shapes.

What shape to choose?

When it comes to choosing a diamond, some shapes can make it look bigger, and certain shapes are trendy right now. But what really matters is what you personally love and what brings you joy. If you can't decide, go for a brilliant cut diamond, which includes shapes like Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant. Round is the most popular, but Oval and Marquise have the power to make the diamond look larger even with the same weight.

Lesson 8 - Setting

The appearance of a 4 carat radiant cut diamond ring can completely change with a different band.

What is setting?

The part of a diamond ring that is made of metal, commonly called the band, is referred to as the setting. They are usually made of gold and come in different colors like white, yellow, or rose. There's also the option of using platinum for the band. The setting plays a huge role in the overall appearance of your 4 carat radiant cut diamond ring. It's a great way to showcase your personal style. The three most popular choices for settings are listed below. Regardless of which one you choose, we suggest sticking with 14k gold. The reason behind this recommendation will be explained as you continue reading.
The setting or band is really important for making your diamond look bigger and better. 

Choose 14 karat gold as the material for your band.

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 Style - A Sleek Band Makes the Diamond Appear Bigger

Survey data indicates that a large diamond is a common desire among women. To visually enhance the size of a 4 carat radiant cut diamond ring, you could consider a Solitaire setting with a slender, elegant band. The disparity between the slim band and the large diamond can create the illusion of a bigger gem. Further enhance this by incorporating petite accent diamonds along the band—they add a touch of elegance without detracting from the main diamond.

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

Looking to make your 4 carat radiant cut diamond ring look even bigger? Give it a boost with a halo setting. This style features smaller diamonds surrounding the main stone, creating a beautiful radiating effect that enhances the appearance of your diamond. For an even more impressive look, give the double halo setting a try. Combined with a slim band, this technique can make even a smaller diamond seem larger, giving off an extravagant vibe.

The main diamond needs to stay the focal point.

Most ladies prefer a big diamond. If your ring band is too fancy or wide, it might take attention away from the diamond and make it appear smaller. If your main focus is the 4-carat radiant cut diamond ring, a simpler band would be ideal. On the other hand, if you prioritize the overall design of the ring, a fancier band might be the right choice, but remember, this could overshadow the diamond.
