Lesson 2 - Clarity

The cost of a 0.4 carat marquise diamond ring is greatly impacted by the clarity of the diamond.

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

What is Clarity?

Clarity in diamonds refers to how easily you can see the imperfections. The important thing to note is that most of these flaws can only be seen under a 10x magnifying glass. The diamond clarity scale ranges from 'flawless' (FL) to 'included' (I), with grades like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included) in between. Diamonds with these clarity grades usually have imperfections that are only visible under 10x magnification, so they will appear perfectly clear to the naked eye. This ensures that anyone admiring your ring won't notice any flaws!

Optimal Clarity Range for a 4.5 carat princess cut diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 4.5 carat princess cut diamond ring can result in substantial savings, possibly reducing the total price by up to $138,330. For the best balance of price and clarity, we strongly suggest considering diamonds in the VS2 range. However, it is important not to disregard SI1 diamonds. By dedicating a few minutes to carefully inspecting the diamonds, you can uncover ones 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 price of a 4.5 carat princess cut diamond ring is significantly influenced by the color of the diamond.

⊗ Up to $74,810 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 hints are usually only noticeable when compared to higher grade diamonds like D, E, or F. Color becomes more apparent in larger diamonds, but a princess diamond in the G-H range will still appear almost colorless and will be less expensive than a completely colorless D-grade diamond.

Optimal Color Range For A 4.5 Carat Princess Cut Diamond Ring

Opting for a princess cut diamond ring with a weight of 4.5 carats allows you to make a bold statement while still maintaining elegance. By carefully considering the color grade, you have the opportunity to save a significant amount of money. Rather than investing in diamonds graded D-F, which come with premium prices, it would be wise to choose a diamond in the G-J range. This decision not only guarantees a stunning piece but also enables you to pocket an impressive amount of up to $74,810 in savings, in addition to any smart 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. 

Look for this Carat Range when shopping for a 4.5 carat princess cut diamond ring.

You might want to check out diamonds in the 4.05 to 4.95 carat range. That way, you'll be able to see nice differences in prices without a big difference in size.

Lesson 6 - Cut

When purchasing your 4.5 carat princess cut diamond ring, remember that the cut of the diamond determines how it sparkles. Opt for an ideal or excellent cut for the most brilliant stone.

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

What is Cut?

If you want to find a really amazing 4.5 carat princess cut diamond ring, you have to focus on the way it's cut. This means looking at how precisely and perfectly the diamond's facets are shaped, which affects how much it shines and sparkles.

A little-known secret within the world of 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.

Don't forget this important tip: always select GIA Certified Excellent Cut Diamonds (often referred to as "Ideal" Cut).

Lesson 7 - Shape

The brilliance of diamonds is influenced by their shape, and specific shapes can contribute to the perceived value of a 4.5 carat princess cut diamond ring.

What is Diamond Shape?

When we discuss the shape of a diamond, we're talking about its design, such as round, oval, or princess. Different shapes can create the illusion of a larger diamond, while others add more sparkle and a classic appearance. Take a look at our shape tool in this section to explore a range of 4.5 carat diamond rings available in numerous shapes.

What shape to choose?

When you're thinking about diamond shapes, it's a fact that certain shapes can give the stone a bigger look, and there are shapes that are currently popular in the market. But what really counts is the shape that speaks to your heart. If you're looking for some guidance, a brilliant cut diamond might be just what you need. This includes shapes like Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant. Out of these choices, Round diamonds are the most commonly loved, while Oval and Marquise shapes can make the diamond look larger even with the same carat weight.

Lesson 8 - Setting

The band of a 4.5 carat princess cut diamond ring can greatly affect its overall appearance.

What is setting?

The band, commonly referred to as the part that holds the diamond, is the metallic part of the ring. It is typically made from gold and is available in white, yellow, or rose gold colors. Platinum is also a choice for the band. The band plays an important role in determining the overall appearance of your 4.5 carat diamond ring with a princess cut. It is a chance to showcase your personal taste. We have listed the three most popular band options below. Regardless of which one you choose, we recommend sticking with 14k gold. Continue reading to find out why.
The setting or band is really important for making your diamond look bigger and better. 

It's always best to go with 14K Gold when selecting your ring band.

Here's a crucial rule to follow. Avoid choosing 18k or 24k gold for your setting. It's better to opt for 14k gold. Despite 18k and 24k gold being more pure, they are considerably softer and prone to bending. If the setting that secures your valuable diamond bends excessively, the chance of the diamond becoming loose and falling out rises significantly. Numerous individuals have faced this issue.

Solitaire Setting - A Slim Band Accentuates the Look of a Larger Diamond

Survey data indicates that a large diamond is a common desire among women. To visually enhance the size of a 4.5 carat princess 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: Give Your Diamond the Illusion of Size with a Bunch of Smaller Ones

For a bigger-looking 4.5 carat princess cut diamond ring, give the halo setting a shot. This setting encircles the main diamond with smaller ones, giving it more sparkle and making it look larger. If you want an even better illusion, think about going for the double halo setting. When paired with a slender band, it can make even a small diamond seem much bigger, giving off the impression of a more impressive ring.

The main diamond should be the focal point.

Many women desire a diamond that looks big and full. A band that is overly decorated or wide might take attention away from the diamond, making it seem smaller. If you want to showcase your 4.5 carat princess cut diamond ring, a plain band would be a good option. However, if you value the overall design of the entire ring, a more detailed band could be the perfect choice. Just remember, this might lessen the impact of the diamond's wow factor.
