Lesson 2 - Clarity

If you're in the market for a 0.4 carat oval diamond ring, remember that the diamond's clarity is the biggest factor in determining its price.

⊗ Up to $225,558 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 flawless they are. However, the interesting part is that these flaws are only visible under a 10x magnifier. The clarity scale ranges from 'flawless' to 'included', with classifications like VS1, VS2, and SI1 in between. Diamonds in these categories usually have imperfections that can only be seen with magnification. So, to the naked eye, they look completely clear, and nobody will notice any flaws when they admire your ring!

Optimal Clarity Range for a 4.5 carat radiant cut diamond ring

By selecting a diamond within the VS2-SI1 clarity range, you have the opportunity to save a significant amount, up to $225,558, on your purchase of a 4.5 carat radiant cut diamond ring. Considering the balance between price and clarity, we strongly advise opting for a VS2 diamond. However, it is important not to disregard SI1 diamonds as well. With just a few minutes of searching through diamonds, you can easily discover SI1 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.

The color of the diamond you choose has a big impact on the price of a 4.5 carat radiant cut diamond ring.

⊗ Up to $42,348 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can have a slight yellow tint or be completely colorless. The Gemological Institute of America (GIA) ranks 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, meaning they have a subtle hint of 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 radiant 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 Radiant Cut Diamond Ring

Opting for the appropriate color grade for a 4.5 carat radiant cut diamond ring can lead to significant cost reductions. Instead of splurging on diamonds graded A-C, consider selecting one in the D-F range. This decision can still produce an exquisite piece while saving you up to $42,348, not to mention any additional savings resulting from astute clarity choices.

Lesson 5 - Carat / Size

Focus on the carat weight as your primary consideration when shopping for a diamond ring.

Why is Carat Important?

Imagine a diamond ring. What's the main attraction? The size of the center diamond, of course. It's no secret - women agree that size is important according to surveys. And since the carat weight determines the size of the diamond, that's where we suggest you spend your money.
Watch us compare sizes and help you visualize what you want. 

Here are the carat options you should consider when looking for a 4.5 carat radiant cut diamond ring.

It would be a good idea to check out diamonds ranging from 4.05 to 4.95 carats. This will help you understand the various price ranges without a significant variation in size.

Lesson 6 - Cut

The cut of a diamond is what gives it that beautiful sparkle. For your 4.5 carat radiant cut diamond ring, make sure to choose either an ideal or excellent cut.

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

What is Cut?

When you're looking for a gorgeous 4.5 carat radiant cut diamond ring, the way it's cut becomes really important. It determines the exactness and flawlessness of the diamond's angles, which then affects the overall shine and brilliance of the ring.

A little-known secret within the world of diamonds.

Sometimes, people think that the fanciest cut diamond, perfectly proportioned to shine the brightest, would cost the most money. But that's not always true. Believe it or not, there are times when a diamond with an average cut, but with the same weight, color, and clarity, can be sold for a higher price. It may sound strange, but poorly cut diamonds can actually look bigger, yet they lack that special sparkle and brilliance. And let's face it, a diamond without sparkle is like having a computer without a screen.

One last thing to keep in mind: go for GIA Certified Excellent Cut Diamonds (also known as "Ideal" Cut).

Lesson 7 - Shape

Diamonds come in many shapes, each with its own sparkle factor, Some of which can give the impression of a higher-priced 4.5 carat radiant cut diamond ring.

What is Diamond Shape?

The diamond shape is all about the way the diamond is cut, like round, oval, and radiant. Some shapes can make the diamond look bigger, while others give it more sparkle and a classic vibe. Check out our shape tool in this section to see a variety of 4.5 carat diamond rings in 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 band has the ability to transform a 4.5 carat radiant cut diamond ring into something completely unrecognizable.

What is setting?

The part of the ring that holds the diamond in place is called the setting or sometimes referred to as the band. Usually, these bands are made of gold and come in different colors like white, yellow, or rose. Another option is platinum bands. The setting plays a big role in how your 4.5 carat radiant cut diamond ring looks. It gives you a platform to display your preferred style. Below, we've mentioned the three most popular settings. It's always recommended to choose a 14k gold band, no matter which setting you choose. The reasons for this will become evident as you continue reading.
The setting or band is really important for making your diamond look bigger and better. 

You should choose a 14K Gold band.

Always keep in mind this important advice. Avoid choosing 18k or 24k gold for your setting. Opt for 14k gold instead. Even though 18k and 24k gold are more pure, they are much softer and more prone to bending. If the setting that holds your precious diamond bends, there is a higher chance of the diamond coming loose and falling out. This is a problem that is commonly encountered.

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

Many women, when surveyed, prefer a large diamond. To emphasize the size of a 4.5 carat radiant cut diamond ring, a thin, delicate band in a Solitaire setting can be considered. The stark contrast between the smaller band and the larger diamond can create an illusion of a larger stone. Accent diamonds along the band can further boost this illusion, providing decorative detail without detracting from the main diamond.

Halo: Enhance the Appearance of Your Diamond by Encircling It with Smaller Ones

If you want to make your 4.5 carat radiant cut diamond ring appear bigger, a halo setting could be the ideal choice. In this arrangement, smaller diamonds encircle the main gem, enhancing its brilliance and apparent size. You can enhance this effect even more by opting for a double halo setting. When combined with a slim band, this can give the illusion of a much larger diamond, creating a sense of extravagant opulence.

Make sure to focus on the main diamond.

Most women prefer their diamond to look big. A fancy or wide band might take away from the diamond's size, making it seem smaller. If you want your 4.5 carat radiant cut diamond ring to be the main attraction, a simpler band could be a good option. However, if you care more about the ring's overall design, a more intricate band might be the way to go, but keep in mind that this could diminish the diamond's standout look.
