Lesson 2 - Clarity

When shopping for a 0.4 carat pear shaped diamond ring, the diamond's clarity is the key factor that affects its pricing.

⊗ Up to $66,128 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 how noticeable any imperfections are. The main focus is on how easily these flaws can be seen, as most of them can only be detected with a 10x magnifying tool. A diamond's clarity can range from 'flawless' (FL) to 'included' (I), with various classifications like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included) falling in between. These types of diamonds typically have imperfections that can only be seen under 10x magnification. So, to the naked eye, they will appear completely clear – meaning anyone admiring your ring won't have a clue about any flaws!

Optimal Clarity Range for a 4.5 carat round diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 4.5 carat round diamond ring can result in significant savings, potentially reducing the total price by as much as $66,128. When considering the balance between price and clarity, we highly recommend opting for a VS2 diamond. However, it is important not to disregard SI1 diamonds. By investing a few minutes in sifting through the available options, you can discover SI1 diamonds that have an appearance that is virtually flawless.

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 you choose for a 4.5 carat round diamond ring greatly affects its price.

⊗ Up to $29,358 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can sometimes have a slight yellow tint or they can be completely 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 fall within the G-H range, which means they have a subtle color. This color is only noticeable when compared to higher grade diamonds like D, E, or F. Larger diamonds tend to show color more prominently, but a round diamond in the G-H range will still appear nearly colorless and be less expensive than a D-grade diamond, which is completely colorless.

Optimal Color Range For A 4.5 Carat Round Diamond Ring

Choosing the right color grade for a 4.5 carat round diamond ring can lead to significant savings. Instead of paying premium prices for diamonds graded D-F, consider opting for a diamond within the G-J range. By making this choice, you can still obtain a breathtaking piece while potentially saving as much as $29,358, in addition to any savings resulting from wise decisions concerning clarity.

Lab-grown diamonds, made through artificial means, possess identical visual characteristics to their naturally occurring counterparts, yet they are produced in a manner that is more environmentally friendly and morally sound. Moreover, their enhanced accessibility offers a more economical option, as a lab-grown diamond can be up to 85% less expensive than a similar naturally formed diamond.

Having a lab-grown diamond can minimize your financial loss if you ever need to sell your 4.5 carat round diamond ring.

Instead of paying premium prices for diamonds graded D-F, consider opting for a diamond within the G-J range.

Lesson 5 - Carat / Size

If you're purchasing a diamond ring, it's wise to focus on the carat weight as a significant factor to consider for your investment.

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. 

Here are the carat ranges you should consider for a 4.5 carat round diamond ring.

We would suggest checking out diamonds that range from 4.05 to 4.95 carats. This way, you can explore different prices without a significant jump in size.

Lesson 6 - Cut

When purchasing your 4.5 carat round diamond ring, keep in mind that the cut of the diamond determines its sparkle and shine. Opt for an ideal or excellent cut to enhance its beauty.

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

What is Cut?

If you're looking for a gorgeous 4.5 carat round diamond ring, you gotta pay attention to the cut. It's crucial because it determines how well the angles are done and that affects how much the ring shines and sparkles.

The diamond companies well-kept secret

You would think that an 'Ideal' cut diamond, which is perfectly proportioned to give you the most sparkle, would always be the most expensive. But the truth is, sometimes a 'Fair' cut diamond with the same carat, color, and clarity can actually cost more than an 'Ideal' cut. It might sound surprising, but here's why: a poorly cut diamond often appears larger, but it lacks the brilliance and sparkle that you're looking for. A diamond without sparkle is basically like a house without a solid foundation.

Here's a valuable tip: always opt for GIA Certified Excellent Cut Diamonds (also known as "Ideal" Cut).

Lesson 7 - Shape

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

What is Diamond Shape?

The style of a diamond is determined by its shape, including options like round, oval, and many more. Certain shapes can create the impression of a bigger diamond, while others provide a brilliant sparkle and a classic appearance. Take a look at our shape tool in this section to explore a wide array of 4.5 carat diamond rings available in various shapes.

What shape to choose?

Certain diamond shapes can create the impression of being bigger, and there are some shapes that are currently popular. However, what truly matters is what you personally find attractive and fulfilling. If you are unsure, a brilliant cut diamond encompassing Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant shapes could be a fantastic option. Among these, Round is the most commonly preferred shape, but Oval and Marquise shapes can make the diamond seem larger even with the same carat weight.

Lesson 8 - Setting

The band can really change the appearance of a 4.5 carat round diamond ring.

What is setting?

The part of a diamond ring that holds the diamond, called the band, is usually made of gold. It can be white, yellow, or rose gold. Another option is a platinum band. The setting plays a big role in how your 4.5 carat round diamond ring looks. It's a chance to show off your personal style. There are three main types of settings, which I'll explain below. No matter which setting you like, it's best to go with 14k gold. I'll explain why as you keep reading.
The setting or band is really important for making your diamond look bigger and better. 

Make sure that the band of your ring is made of 14 karat gold.

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

As per surveys, the majority of women desire a significantly large diamond. A setting with a thin, delicate Solitaire band could accentuate the size of a 4.5 carat round diamond ring. The juxtaposition of the small band with the large diamond creates an illusion of a more expansive stone. Small accent diamonds embedded in the band can further this illusion, adding a touch of elegance without detracting from the primary diamond.

Halo: Give Your Diamond the Illusion of Size with a Bunch of Smaller Ones

For a ring that makes a 4.5 carat round diamond look larger, give the halo setting a shot. This particular setting encircles the main diamond with smaller ones, causing it to sparkle and seem bigger. If you really want to create an even greater illusion, think about going for the double halo setting. Pair it with a slim band, and even a small diamond will seem much larger, giving off the impression of a more extravagant ring.

Maintain the Main Diamond's Dominance

Most women like a big diamond. If your ring is too fancy or wide, it can make the diamond look smaller. If you really care about the 4.5 carat round diamond, a simpler band might be better. On the other hand, if you value the overall design of the ring more, a fancier band could be the right choice, but remember, it could take attention away from the diamond.
