Lesson 2 - Clarity

When shopping for a 0.4 carat diamond ring, the diamond's clarity is the primary pricing factor to keep in mind.

⊗ Up to $138,330 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

In the world of diamonds, clarity refers to the presence of noticeable flaws. It's worth mentioning that these flaws are usually only visible when you look at the diamond through a 10x magnifying glass. Diamond clarity is categorized from "flawless" to "included". In the middle, you'll come across classifications like VS1, VS2, and SI1. These diamonds may have imperfections that can only be seen with 10x magnification. To the naked eye, they look absolutely flawless, so nobody will be able to notice any imperfections when they admire your ring!

Optimal Clarity Range for a 4.5 carat marquise diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 4.5 carat marquise diamond ring can result in significant savings, potentially reducing the total price by as much as $138,330. When it comes to finding the perfect balance between price and clarity, we highly recommend opting for a VS2 diamond. However, it is important not to disregard SI1 diamonds. With just a few minutes dedicated to sifting through the available options, you can discover SI1 diamonds that appear flawlessly stunning.

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 you choose has a significant impact on the price of a 4.5 carat marquise diamond ring.

⊗ Up to $74,810 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can have a yellow tint or be completely colorless. The GIA grades them on a scale from D (colorless) to Z (yellow or brown). Most diamonds used in jewelry are in the G-H range, which means they have a slight color but it's only noticeable when compared to higher-grade diamonds like D, E, or F. While color differences are more noticeable in larger diamonds, a marquise diamond in the G-H range will still appear almost colorless and will be cheaper than completely colorless diamonds with a D-grade.

Optimal Color Range For A 4.5 Carat Marquise Diamond Ring

Opting for the appropriate color grade when selecting a 4.5 carat marquise diamond ring can lead to significant cost savings. Instead of investing in higher-priced D-F graded diamonds, consider choosing a diamond within the G-J range. By doing so, not only can you still acquire a breathtaking piece, but you could also save as much as $74,810, in addition to any savings achieved through astute decisions regarding clarity.

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

Discover How Lab Grown Diamonds Can Slash $78,600 off the Price of your 4.5 Carat Marquise Diamond Ring.

Lab-grown diamonds, which are created in a lab rather than mined from the earth, have the same visual qualities as diamonds found in nature. They are produced in a more environmentally friendly and ethical manner. Additionally, lab-grown diamonds are more readily available and therefore much more affordable. In fact, the cost of a lab-grown diamond can be up to 85% lower than that of a comparable natural diamond.

If you ever decide to sell your 4.5 carat marquise diamond ring, choosing a lab-grown diamond can help you minimize your financial loss.

Opting for the appropriate color grade when selecting a 4.5 carat marquise diamond ring can lead to significant cost savings. Instead of investing in higher-priced D-F graded diamonds, consider choosing a diamond within the G-J range. By doing so, not only can you still acquire a breathtaking piece, but you could also save as much as $74,810, in addition to any savings achieved through astute decisions regarding clarity.

Lesson 5 - Carat / Size

Focus your money on carat weight when you are shopping for a diamond ring.

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. 

If you're looking for a marquise diamond ring weighing 4.5 carats, choose a ring within this carat range.

You should check out diamonds that range from 4.05 to 4.95 carats. This will give you a good sense of how prices vary without a significant difference 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 4.5 carat marquise diamond ring.

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

What is Cut?

When searching for a remarkable 4.5 carat marquise diamond ring, one important aspect to take into account is the diamond's cut. Essentially, the cut refers to the precise shaping of all the diamond's facets, which directly impacts its overall sparkle and brilliance.

What diamond companies don't want you to know

You might think that an 'Ideal' cut diamond, which is famous for its perfectly sparkly appearance, is always the most expensive. Well, it turns out that this assumption isn't always accurate. Surprisingly enough, a 'Fair' cut diamond with the same carat, color, and clarity can sometimes be even pricier. It might sound strange, but poorly cut diamonds can actually appear larger while lacking that desired sparkle and brilliance. A diamond without any sparkle is just like a guitar without any strings.

Remember this final advice: stick with GIA Certified Excellent Cut Diamonds (commonly called "Ideal" Cut).

Lesson 7 - Shape

The sparkle of a diamond can vary based on its shape, and certain shapes can make 4.5 carat marquise diamond rings appear more expensive.

What is Diamond Shape?

The diamond shape is all about the style of the diamond, like round, oval, and marquise. Different shapes can give the diamond a bigger look or more sparkle, and even a classic vibe. Check out the shape tool in this section to see a variety of 4.5 carat diamond rings with different shapes.

What shape to choose?

Some of these shapes will indeed give the diamond the appearance of being larger, and there are certain shapes that are considered trendy. However, at the end of the day, the most important factor in making this decision should be what catches your attention and brings you the most joy. If you don't have a preference, then I would suggest going for a brilliant cut diamond, which includes shapes such as Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant. Out of these, Round is the most commonly chosen shape. On the other hand, if you want the diamond to appear larger for the same carat weight, then Oval and Marquise shapes would be the way to go.

Lesson 8 - Setting

The way the band looks can really affect the overall attractiveness of a 4.5 carat marquise diamond ring.

What is setting?

The main part of a diamond ring, also known as the band, is called the setting. Typically, it's made of gold and comes in different colors like white, yellow, or rose gold. Another option is a platinum band. The setting plays a big role in determining the overall appearance of your 4.5 carat marquise diamond ring. It allows you to express your personal style. In this article, we'll discuss the three most popular settings right now. No matter which one you choose, it's recommended to go with 14k gold. As you continue reading, you'll discover the reasons why.
The setting or band is really important for making your diamond look bigger and better. 

Try to get a 14K gold band for your ring.

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 Ring - A Thin Band Makes Your Diamond Appear Bigger.

Survey data indicates that a large diamond is a common desire among women. To visually enhance the size of a 4.5 carat marquise 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: Use smaller diamonds to make your diamond look bigger.

A halo setting is a fantastic option to give your 4.5 carat marquise diamond ring a bigger appearance. This setting features smaller diamonds encircling the main stone, creating a radiant glow that enhances the size of the central diamond. For an even more striking effect, think about a double halo setting. When combined with a slender band, this type of setting can make a smaller diamond appear larger, resulting in a truly impressive piece.

Ensure that the main diamond remains the center of attention.

Most ladies prefer a big diamond. If your ring has too much decoration or is wide, it might make the diamond look smaller. If you really care about having a 4.5 carat marquise diamond ring, a simpler band may be the best choice. On the other hand, if you care more about the overall design of the ring, a fancier band might be the one for you. Just remember, this could take attention away from the diamond.
