Lesson 2 - Clarity

If you're in the market for a 0.33 carat pear shaped diamond ring, remember that the diamond's clarity is the main determinant of its price.

⊗ Up to $58,099 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 4 carat round diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 4 carat round diamond ring can result in significant savings, potentially reducing the total price by as much as $58,099. When considering the clarity options, we strongly suggest opting for VS2 as it offers a great balance between price and clarity. However, it is important not to disregard SI1 diamonds. By investing a few minutes in carefully examining the diamonds, you may discover ones that have 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 round diamond ring is greatly affected by the color of the diamond selected.

⊗ Up to $21,903 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can vary in color, ranging from yellow to colorless. The Gemological Institute of America (GIA) rates diamonds on a scale from D (colorless) to Z (yellow or brown). The majority of diamonds used in jewelry have a slight color, falling within the G-H range. These subtle color differences are usually only noticeable when compared to higher-grade diamonds like D, E, or F. Color is more noticeable in larger diamonds, but a round diamond from the G-H range will still appear almost colorless and will be less expensive than a completely colorless diamond, such as a D-grade diamond.

Optimal Color Range For A 4 Carat Round Diamond Ring

When selecting a 4 carat round diamond ring, opting for a diamond in the G-H color range is recommended for more intricate designs. This ensures that there won't be any noticeable color contrast between the central diamond and the smaller diamonds encircling it, which are typically colorless or near-colorless. By following this approach, you can achieve a stunning piece while avoiding any potential discrepancies that might occur with lower graded diamonds.

Lesson 5 - Carat / Size

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

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. 

This range of carats is the most ideal choice for a 4 carat round diamond ring.

We suggest checking out diamonds that range from 3.6 to 4.4 carats. This way, you can see different prices without a significant increase in size.

Lesson 6 - Cut

When buying your 4 carat round diamond ring, remember that the cut of the diamond is what gives it that brilliant sparkle. Stick to ideal or excellent cut options.

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

What is Cut?

When you're on the hunt for the most stunning 4 carat round diamond ring, keep in mind that the way it's cut plays a major role in how much it sparkles and shines. The cut refers to how precisely and perfectly the diamond's angles are done.

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 sparkle of a diamond can vary based on its shape, and certain shapes can make 4 carat round diamond rings appear more expensive.

What is Diamond Shape?

When we talk about the shape of a diamond, we're talking about its style. There are numerous shapes to choose from, such as round, oval, and many others. Each shape has its own characteristics that can make the diamond appear larger or enhance its sparkle. Additionally, different shapes offer a classic and timeless appeal. In this section, you can explore a selection of 4 carat diamond rings with various shapes using our helpful shape tool.

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 round diamond ring can vary greatly depending on the band it is set in.

What is setting?

The metal part of the diamond ring, also called the band, is known as the setting. Usually, it's made of gold and comes in white, yellow, or rose colors. You can also opt for a platinum band. The setting is extremely important for the overall look of your 4 carat round diamond ring. This is where you can express your own style. Below, we've listed the three most popular settings. No matter which one you choose, we recommend going with 14k gold. Keep reading to find out why we suggest this.
The setting or band is really important for making your diamond look bigger and better. 

Choose 14K Gold for your 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 - A Thinner Band to Make the Diamond Look Larger

Survey data indicates that a large diamond is a common desire among women. To visually enhance the size of a 4 carat round 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: Give Your Diamond the Illusion of Size with a Bunch of Smaller Ones

A halo setting is a fantastic option to give your 4 carat round diamond ring a larger appearance. This type of setting incorporates smaller diamonds encircling the main stone, giving it a glowing aura that enhances the size of the central diamond. To achieve an even more substantial effect, you may want to consider a double halo setting. When paired with a slim band, this setting can create an illusion that makes a smaller diamond appear larger, resulting in a truly remarkable piece.

Stay focused on the main diamond

Many women want a diamond that appears as large as possible. A band that is overly fancy or wide can take away attention from the diamond, making it seem smaller in comparison. If you want your 4 carat round diamond ring to be a standout, opting for a simpler band may be a good idea. However, if you value the overall design of the entire ring, a detailed band might be your preference, but keep in mind that this could lessen the diamond's impressive appearance.
