Lesson 2 - Clarity

If you're in the market for a 1 carat radiant cut diamond ring, remember that the diamond's clarity is the biggest factor in determining its price.

⊗ Up to $655,967 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

When we talk about clarity in diamonds, we're basically talking about how visible the flaws are. But it's important to note that most flaws can only be seen with a 10x magnifying glass. Diamond clarity goes from 'flawless' to 'included'. In the middle, you'll find classifications like VS1, VS2, and SI1. These diamonds might have flaws that can only be seen with 10x magnification. To the naked eye, they look completely clear, so nobody will notice any imperfections when they admire your ring!

Optimal Clarity Range for a 8.5 carat cushion cut diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 8.5 carat cushion cut diamond ring can result in significant savings, with the potential to save as much as $655,967 off the total price. Considering the balance between price and clarity, we highly recommend opting for a VS2 diamond. However, it's important not to overlook SI1 diamonds either. By dedicating just a few minutes to sifting through diamonds, 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 the diamond has a big impact on the price of an 8.5 carat cushion cut diamond ring.

⊗ Up to $79,800 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can vary in color, ranging from yellow to 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 have a slight color, falling within the G-H range. These subtle color differences are typically only noticeable when compared to higher-grade diamonds like D, E, or F. While color is more noticeable in larger diamonds, a diamond from the G-H range will still appear almost colorless and will be less expensive than a completely colorless diamond, such as a D-grade diamond.

Optimal Color Range For A 8.5 Carat Cushion Cut Diamond Ring

Opting for the appropriate color grade for an 8.5 carat cushion cut diamond ring can lead to significant cost reductions. Instead of investing in extravagant-priced diamonds with color grades of D-F, contemplate selecting a diamond falling within the G-J range. This decision can still provide you with an astonishing piece, all while saving you a whopping $79,800, in addition to any savings derived from astute decisions concerning clarity.

Lab Grown Diamonds

Lab grown diamonds can often cut prices in half and no one will ever notice the difference. 

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

Save over $400,000 on your 8.5 carat cushion cut diamond ring with a lab grown diamond.

Lab-grown diamonds are diamonds that are created in a laboratory setting. These diamonds possess identical visual characteristics to those found in nature but are manufactured in a manner that is more environmentally friendly and morally sound. Additionally, lab-grown diamonds are more budget-friendly because they are more readily accessible than natural diamonds. In fact, a lab-grown diamond can be up to 85% cheaper than a similar diamond found in nature.

When it comes to selling your 8.5 carat cushion cut diamond ring, choosing a lab-grown diamond can help mitigate your financial loss.

Opting for the appropriate color grade for an 8.5 carat cushion cut diamond ring can lead to significant cost reductions. Instead of investing in extravagant-priced diamonds with color grades of D-F, contemplate selecting a diamond falling within the G-J range. This decision can still provide you with an astonishing piece, all while saving you a whopping $79,800, in addition to any savings derived from astute decisions concerning clarity.

Lesson 5 - Carat / Size

Invest more in carat size for a bigger gem in your diamond ring.

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. 

The Best Carat Range for Shopping for an 8.5 Carat Cushion Cut Diamond Ring

You might want to think about looking at diamonds that range from 7.65 to 9.35 carats. This will give you a nice variety of prices without a big jump in size.

Lesson 6 - Cut

It's important to understand that the cut of a diamond directly impacts its sparkle. When buying your 8.5 carat cushion cut diamond ring, choose an ideal or excellent cut to enhance its brilliance.

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 stunning 8.5 carat cushion cut diamond ring, the way it's cut becomes really important. The cut determines how precise and flawless the diamond's angles are, and ultimately affects the ring's overall shine and radiance.

The diamond companies well-kept secret

Although people usually assume that an 'Ideal' cut diamond, which is perfectly proportioned for maximum sparkle, would be the most expensive, there are cases where a 'Fair' cut diamond with similar carat, color, and clarity can actually be pricier. This might sound strange, but diamonds that are poorly cut can appear larger even though they lack the desired sparkle and brilliance. A diamond without sparkle is similar to a puzzle without pieces.

Don't forget this important tip: always select GIA Certified Excellent Cut Diamonds (often referred to as "Ideal" Cut).

Lesson 7 - Shape

The sparkliness of diamonds varies depending on their shape, and some shapes can add to the perceived value of a 8.5 carat cushion cut diamond ring.

What is Diamond Shape?

When we refer to the diamond shape, we're talking about the way the diamond is cut, like round, oval, or cushion. Different shapes can create the illusion of a larger diamond, while others bring out more sparkle and a classic appeal. Take a look at our shape tool in this section and you'll find a variety of 8.5 carat diamond rings with various shapes to choose from.

What shape to choose?

It's a fact that certain diamond shapes can create the illusion of a larger stone, and currently, some shapes are seen as more fashionable. But when you're deciding, keep in mind that what really counts is what catches your eye and brings you the most joy. If you're unsure and don't have a specific preference, you might want to think about a brilliant cut diamond. This includes shapes like Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant. While Round is the most popular choice, Oval and Marquise shapes can give the diamond a bigger appearance with the same carat weight.

Lesson 8 - Setting

The appearance of an 8.5 carat cushion cut diamond ring can vary significantly depending on the band it is paired with.

What is setting?

The part of a diamond ring that holds the gem, commonly known as the band, is called the setting. These are usually made of gold and come in different colors like white, yellow, or rose. There is also the option of a platinum band. The setting plays a crucial role in the overall appearance of your 8.5 carat cushion cut diamond ring. It provides a great opportunity to showcase your personal style. The three most popular settings are mentioned below. Regardless of your choice, we suggest going for 14k gold. We will explain the reasons for this recommendation as you continue reading.
The setting or band is really important for making your diamond look bigger and better. 

Go with 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 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 8.5 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: Enhance the Appearance of Your Diamond with Smaller Stones Around It

To make your 8.5 carat cushion cut diamond ring appear bigger, think about using a halo setting. The little diamonds around it make the main stone look brighter and larger. You might want to go for a double halo setting for an even more impressive illusion. When combined with a thin band, this can turn a smaller diamond into a much larger and fancy gem.

Do not overshadow the main diamond.

A lot of women like their diamond to appear big. If your ring band is too fancy or wide, it can shift attention away from the diamond, making it seem smaller in comparison. If you're mainly interested in the 8.5 carat cushion cut diamond ring as the highlight, then a simpler band would be your safest choice. On the other hand, if the overall design of the ring is your main priority, a more intricate band could be a perfect fit for you. However, keep in mind that this might reduce the visibility of the diamond.
