Lesson 2 - Clarity

When shopping for a 0.2 carat radiant cut diamond ring, the clarity of the diamond plays a major role in determining its price.

⊗ Up to $19,079 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

Clarity is a word used to describe the imperfections in a diamond that can be seen. However, it's important to remember that these imperfections are usually only visible when you look at the diamond through a 10x magnifying glass. Diamond clarity ranges from "flawless" to "included". In between, you'll find 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 completely perfect, so nobody will be able to see any flaws when they admire your ring!

Optimal Clarity Range for a 3 carat cushion cut diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 3 carat cushion cut diamond ring can result in significant savings, potentially reducing the total price by as much as $19,079. When considering the clarity options, we highly recommend choosing a diamond in the VS2 range. This choice strikes a perfect balance between price and clarity. However, it is important not to overlook SI1 diamonds. By taking just a few minutes to sift through the available options, you can find SI1 diamonds that appear 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 cost of a 3 carat cushion cut diamond ring is greatly influenced by the diamond's color.

⊗ Up to $11,706 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can come in a slightly yellowish hue or be completely colorless. The Gemological Institute of America (GIA) categorizes them from D (no color) to Z (yellow or brown). Most diamonds used in jewelry have a slight tint, falling within the G-H range. Any faint traces of color can only be noticed when compared to higher-grade diamonds like D, E, or F. While larger diamonds tend to show more color, a cushion diamond in the G-H range will still look almost colorless and cost less than a D-grade diamond, which is completely colorless.

Optimal Color Range For A 3 Carat Cushion Cut Diamond Ring

Selecting the appropriate color grade for a 3 carat cushion cut diamond ring can lead to significant cost reductions. Instead of paying premium prices for diamonds graded D-F, consider opting for diamonds within the G-J range. This decision can still result in an exquisite piece while saving you up to $11,706, in addition to potential savings based on judicious clarity choices. For more intricate designs like a halo diamond ring, which features numerous smaller diamonds encircling the central stone, it is advisable to choose a diamond in the G-H color range. This strategy helps prevent any noticeable color discrepancies that may arise when comparing I-J graded diamonds to the smaller, usually colorless or nearly colorless diamonds in the halo.

Save up to 85% on your diamond ring.

Discover How Lab Grown Diamonds Can Help You Save an Astonishing $25,900 on Your 3 Carat Cushion Cut Diamond Ring.

Lab-grown diamonds, also called lab-created diamonds, possess an indistinguishable look from genuine diamonds but are manufactured in a more environmentally friendly and morally conscious process. Additionally, they offer a greater affordability owing to their increased accessibility compared to natural diamonds. In fact, a lab-grown diamond can be up to 85% cheaper than a similar natural diamond.

If you ever decide to part ways with your 3 carat cushion cut diamond ring, choosing a lab-grown diamond can help reduce your financial loss.

Lesson 5 - Carat / Size

Focus on the carat weight when you're shopping for a diamond ring.

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. 

The best option for a cushion cut diamond ring with a carat range of 3 carats is your safest bet.

We recommend looking at diamonds that range from 2.7 to 3.3 carats. This will give you a variety of prices without a significant increase in size.

Lesson 6 - Cut

The way a diamond is cut directly affects its sparkle. For your 3 carat cushion 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 remarkable diamond, you have to consider the cut. The cut is extremely important in determining the quality of the diamond's sparkle and brilliance because it involves the precise shaping of all the facets.

A hidden truth within the diamond industry

An 'Ideal' cut diamond is known for its maximum sparkle and is often thought to be the most expensive. But sometimes, a 'Fair' cut diamond with the same carat, color, and clarity can be even pricier. It may seem confusing, but poorly cut diamonds can appear larger without giving off the desired sparkle and brilliance. A diamond that lacks sparkle is like a garden without any soil.

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

Lesson 7 - Shape

When selecting diamonds, keep in mind that different shapes offer distinct levels of sparkle, and certain shapes can create the illusion of a pricier 3 carat cushion cut diamond ring.

What is Diamond Shape?

The shape of a diamond determines its style, such as being round, oval, or cushion-shaped. There are actually many more shapes to choose from when it comes to diamonds. Certain shapes can give the illusion of a bigger diamond, while others offer more brilliance and a traditional, everlasting charm. To explore a range of 3 carat diamond rings with various shapes, you can utilize our shape tool located in this section.

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 band of a 3-carat cushion cut diamond ring can have a significant impact on its overall appearance.

What is setting?

The part of the ring that holds the diamond is called the setting or sometimes the band. Usually, these bands are made of gold and come in different colors like white, yellow, or rose. Another option is a platinum band. The setting plays a big role in how your 3 carat cushion cut diamond ring looks. It gives you a place to show off your personal style. We're going to talk about the three most popular settings below. It's always best to go with 14k gold, no matter which setting you pick. As you keep reading, you'll understand why.
The setting or band is really important for making your diamond look bigger and better. 

Your band ought to be made of 14 karat gold.

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 - A Thinner Band to Make the Diamond Look Larger

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 3 carat cushion cut 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: Increase the size of your diamond by surrounding it with tiny gems.

The halo setting provides a different approach to make your 3 carat cushion cut diamond ring look even bigger. It surrounds the main diamond with smaller ones, giving off a dazzling effect that amplifies the size of the central diamond. If you want to go for an even more striking illusion, you can choose a double halo setting. Combining it with a slender band can make a smaller diamond appear remarkably larger, creating the impression of a more luxurious piece.

Ensure that the main diamond remains the center of attention.

Many women prefer a diamond that looks big and noticeable. A band that is too fancy or wide might take away from the diamond, making it seem smaller. If you want your 3 carat cushion cut diamond ring to be the main attraction, it would be smart to choose a simple and inconspicuous band. On the other hand, if you care more about how the ring looks as a whole, a fancy band might be your preferred choice, but be cautious, as it could make the diamond appear less prominent.
