Lesson 2 - Clarity

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

⊗ Up to $20,479 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

Diamond clarity refers to how many imperfections a diamond has that can be seen. However, when we say "detectable," we mostly mean that these flaws can only be seen with a 10x magnifying lens. Clarity in diamonds ranges from 'flawless' (FL) to 'included' (I), with classifications in between like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included). These diamonds usually have imperfections that can only be seen with a 10x magnifying glass, so they will appear perfectly clear to the naked eye - meaning nobody will notice any flaws when they look at your ring!

Optimal Clarity Range for a 4.5 carat cushion cut diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 4.5 carat cushion cut diamond ring can result in substantial savings, potentially reducing the total price by as much as $20,479. We suggest considering the VS2 clarity grade, as it offers a great balance between price and clarity. However, it's important not to disregard SI1 diamonds either - with just a few minutes of searching through available options, you can discover diamonds that appear nearly 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 of the diamond you choose greatly affects the price of a 4.5 carat cushion cut diamond ring.

⊗ Up to $22,955 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) rates diamonds on a scale from D (no color) to Z (yellow or brown color). The majority of diamonds used in jewelry fall within the G-H range, which means 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 even a cushion 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 Cushion Cut Diamond Ring

Opting for the appropriate color grade in a 4.5 carat cushion cut diamond ring can lead to considerable cost reductions. Instead of investing in pricy D-F graded diamonds, contemplate selecting a diamond falling within the G-J range. This decision can still yield a remarkable piece while saving you a whopping $22,955, in addition to any savings derived from astutely addressing clarity concerns.

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

Save up to $58,900 on your 4.5 carat cushion cut diamond ring by opting for a lab grown diamond.

Lab-grown diamonds, also known as man-made diamonds, possess the benefit of appearing identical to natural diamonds, while being created through a sustainable and ethical process. Moreover, their affordability is enhanced due to their increased availability compared to natural diamonds. In fact, a lab-grown diamond can cost up to 85% less than a similar natural diamond.

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

Opting for the appropriate color grade in a 4.5 carat cushion cut diamond ring can lead to considerable cost reductions. Instead of investing in pricy D-F graded diamonds, contemplate selecting a diamond falling 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?

When you imagine a diamond ring, what do you picture? That's correct - the size of the main diamond. Women also prioritize size, so if you're unsure where to invest your money, we advise focusing on carat weight - it's the ultimate size determinant in the diamond industry.
Watch us compare sizes and help you visualize what you want. 

If you're looking for a 4.5 carat cushion cut diamond ring, choose from this range of carats.

We recommend looking at diamonds ranging from 4.05 to 4.95 carats. This way, you can explore different price options without a significant jump in size.

Lesson 6 - Cut

The cut of a diamond is what gives it that special sparkle. When buying your 4.5 carat cushion cut diamond ring, make sure to choose 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 it comes to a stunning 4.5 carat cushion cut diamond ring, the way it is cut plays a vital role. The diamond's facets need to be precisely and perfectly done to really bring out its sparkle and brilliance.

A little-known secret within the world of diamonds.

When it comes to diamond cuts, the 'Ideal' cut is often seen as the most valuable since it's designed to make the diamond shine the most with perfect proportions. But, you might be surprised to learn that sometimes a 'Fair' cut diamond, with the same carat, color, and clarity, could actually be pricier. Sounds weird, doesn't it? Well, that's because diamonds that are poorly cut might look bigger but they lack the sparkle and brilliance that you're looking for. A diamond without sparkle is basically like a boat without water.

Here's a valuable tip: always opt for GIA Certified Excellent Cut Diamonds (also known 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 cushion cut diamond ring.

What is Diamond Shape?

The shape of a diamond determines its style, whether it's round, oval, cushion, or any number of other options. Certain shapes can make a diamond appear bigger, while others provide extra sparkle and a classic aesthetic. Explore our shape selection tool in this section to discover a range of 4.5 carat diamond rings with different shapes.

What shape to choose?

Sure, some diamond shapes can make the stone look bigger, and some shapes are popular right now. But remember, what really counts is what makes you the happiest. If you're not sure, a brilliant cut diamond, such as Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant shapes, might be your best bet. Out of these, Round diamonds are the most popular, while Oval and Marquise shapes can give the impression of a larger diamond without weighing more.

Lesson 8 - Setting

The band can transform a 4.5 carat cushion cut diamond ring into something completely unrecognizable.

What is setting?

Often referred to as the band, the setting is the golden part of the diamond ring. It is typically made of gold in different shades like white, yellow, or rose gold. Another option to consider is a platinum band. The setting plays a vital role in enhancing the overall appearance of your 4.5 carat cushion cut diamond ring. This is where you can showcase your personal style preferences. Below, we have highlighted the top three most favored settings. Regardless of your selection, we suggest sticking with 14k gold. We will explain the reasons behind this recommendation later on.
The setting or band is really important for making your diamond look bigger and better. 

We suggest opting for a 14K gold band for your ring.

Here's a really important tip. Avoid choosing between 18 karat or 24 karat gold for your setting. It's better to go with 14 karat gold instead. Even though 18 karat and 24 karat gold are more pure, they are much softer and prone to bending easily. If the setting of your valuable diamond bends too easily, it greatly raises the risk of the diamond slipping out. Many people have faced this issue before.

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 cushion 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: Boost Your Diamond's Volume with Many Small Gems

The halo setting provides an additional method to make your 4.5 carat cushion cut diamond ring look bigger. By surrounding the main diamond with smaller ones, it produces a dazzling effect that enhances the size of the main diamond. For an even more striking illusion, you can choose a double halo setting. When combined with a slender band, this can make a smaller diamond appear significantly larger, creating the impression of a more luxurious piece of jewelry.

The main diamond should be the focal point.

Many women prefer a diamond that appears substantial. A band that is too ornate or wide might take away attention from the diamond, making it seem smaller. If you want your 4.5 carat cushion cut diamond ring to be the main focus, selecting a simple and unobtrusive band would be a smart decision. On the other hand, if you care more about the overall look of the ring, a fancy band might be your preferred choice, but be careful as it could diminish the diamond's prominence.
