Lesson 2 - Clarity

The pricing of a 2.5 carat cushion cut diamond ring is primarily determined by the clarity of the diamond.

⊗ Up to $46,454 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 the presence of noticeable flaws. It's important to mention that these flaws are usually only visible when using a 10x magnifying glass. Diamond clarity is categorized from 'flawless' to 'included'. In the middle, you'll come across 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 absolutely flawless, so nobody will be able to notice any blemishes when they admire your ring!

Optimal Clarity Range for a 2.5 carat cushion cut diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 2.5 carat cushion cut diamond ring can result in significant cost savings, potentially reducing the total price by as much as $46,454. When considering the clarity of the diamond, we highly recommend opting for a VS2 grade. This choice strikes a perfect balance between price and clarity. However, it is important not to overlook SI1 diamonds. With just a few minutes spent sifting through the available options, you can easily 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 color of a diamond is a major factor in determining the price of a 2.5 carat cushion cut diamond ring.

⊗ Up to $7,229 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can have a yellowish tint or no color at all. The Gemological Institute of America (GIA) ranks diamonds on a scale from D (colorless) to Z (yellow or brown). Most diamonds used in jewelry have a slight amount of color and fall within the G-H range. The subtle hints of color in these diamonds are usually only noticeable when compared to higher graded diamonds like D, E, or F. While larger diamonds may show color more prominently, a cushion diamond from the G-H range will still appear nearly colorless and will be less expensive than completely colorless diamonds, such as those in the D-grade.

Optimal Color Range For A 2.5 Carat Cushion Cut Diamond Ring

Opting for a 2.5 carat cushion cut diamond ring enables you to revel in its remarkable beauty while potentially enjoying significant cost savings. Rather than investing in higher-priced diamonds graded D-F, consider selecting a diamond within the G-J range. This decision not only guarantees an exquisite piece but can also lead to savings of up to $7,229 alongside any other prudent choices made regarding clarity.

Lesson 5 - Carat / Size

When searching for a diamond ring, prioritize the carat weight as the main factor to consider when deciding where to allocate your budget.

Why is Carat Important?

Let's be honest about diamond rings. The main focus is on the size of the center diamond, isn't it? And guess what, ladies agree! Surveys reveal that the size of the diamond is their top priority. Considering that the carat weight determines the diamond's size, we suggest allocating your budget accordingly.
Watch us compare sizes and help you visualize what you want. 

This carat range is the top choice for a 2.5 carat cushion cut diamond ring.

You might want to consider checking out diamonds that are between 2.25 and 2.75 carats. This will give you a good idea of various price options without a big jump in size.

Lesson 6 - Cut

The cut of a diamond is what gives it that special sparkle. When buying your 2.5 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?

If you want to find an incredibly beautiful cushion cut diamond ring that is 2.5 carats, you should focus on its cut. The cut of a diamond refers to how perfectly its facets have been shaped, which ultimately affects its sparkle and shine.

The diamond companies well-kept secret

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.

Last but not least, make sure to go for GIA Certified Excellent Cut Diamonds (sometimes referred to 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 2.5 carat cushion cut diamond ring.

What is Diamond Shape?

The diamond shape is all about how the diamond looks. It can be round, oval, cushion, and many more. Depending on the shape, the diamond can appear bigger or have more shine, giving it a classic look. In this section, you can check out our shape tool and browse through various 2.5 carat diamond rings with different shapes.

What shape to choose?

It's important to recognize that certain diamond cuts can give off the illusion of a bigger gem, and there are some cuts that are currently in style. Nevertheless, the most important decision is the one that truly speaks to you. If you're unsure about which cut to go for, think about getting a brilliant cut diamond. This includes shapes like Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant. Out of all these options, Round diamonds are the ones that get chosen most frequently, while Oval and Marquise cuts can make a diamond look bigger without increasing the carat weight.

Lesson 8 - Setting

The appearance of a cushion cut diamond ring with 2.5 carats can undergo a drastic transformation depending on the band it is paired with.

What is setting?

Sometimes called the ring's band, the setting is the golden part of the diamond ring. Usually, these bands are made of gold and come in various colors such as white, yellow, or rose gold. If you like, you can also choose a platinum band. The setting has a crucial role in determining the overall look of your 2.5 carat cushion cut diamond ring. It gives you an opportunity to showcase your personal style. We have gathered the top three settings that are most commonly preferred. Regardless of your choice, it is recommended to go for 14k gold. Continue reading to understand why this is the case.
The setting or band is really important for making your diamond look bigger and better. 

Choose 14K Gold for your band.

Here's an important rule to remember: try not to choose 18k or 24k gold for your setting. Your safest option is 14k gold. Even though 18k and 24k gold are purer, they are noticeably softer and more likely to bend. If the band holding your precious diamond can easily bend, there's a big chance that the diamond might come loose. This is a problem that many people often face.

Solitaire - A Great Band for a Flashier Diamond Presentation

Many women, when surveyed, prefer a large diamond. To emphasize the size of a 2.5 carat cushion 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: Give Your Diamond the Illusion of Size with a Bunch of Smaller Ones

The halo setting offers a different way to make your 2.5 carat cushion cut diamond ring look bigger. By putting smaller diamonds around the main one, it creates a dazzling effect that makes the center diamond appear larger. If you want an even more striking effect, you could choose a double halo setting. Coupled with a slim band, this can make a smaller diamond appear much larger, giving the impression of a more luxurious piece.

Keep the focus on the main diamond.

Many women desire a diamond that looks impressive. Choosing a band that is overly ornate or wide can distract attention from the diamond and make it appear smaller. If you want to showcase your 2.5 carat cushion cut diamond ring as the main focus, it would be wise to choose a simpler band that doesn't overshadow the stone. However, if you value the overall design of the ring more, a detailed band might be a good choice. Just keep in mind that it could diminish the diamond's standout quality.
