Lesson 2 - Clarity

The pricing of a 1.5 carat oval diamond ring is primarily influenced by the clarity of the diamond

⊗ 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 remember that most flaws can only be seen with a 10x magnifying glass. Diamond clarity ranges from 'flawless' to 'included'. In the middle, there are classifications like VS1, VS2, and SI1. These diamonds might have flaws that can only be seen under 10x magnification. To the naked eye, they look completely perfect, so nobody will notice any imperfections when they admire your ring!

Optimal Clarity Range for a 8.5 carat radiant cut diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 8.5 carat radiant cut diamond ring can result in significant savings, possibly reducing the total price by up to $655,967. We highly suggest considering VS2 diamonds due to their favorable combination of price and clarity. However, it is also important not to dismiss SI1 diamonds, as with a little time spent searching through options, you can discover ones that exhibit 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.

What is Color?

Diamond color is determined by the presence or absence of a yellow hue. The GIA rates diamond color on a scale from D (no color) to Z (light yellow or brown). When it comes to making jewelry, diamonds that are close to colorless, falling within the G-H range, are typically used. It can be difficult to spot any minor traces of color in these diamonds unless they are compared to higher-graded ones. It's important to note that the differences in diamond color are usually extremely subtle and may go unnoticed by someone without training. However, in larger diamonds, the color may become more noticeable. A diamond within the G-H range, which is almost colorless, will appear that way and be priced more favorably compared to diamonds that are more colorless.

Optimal Color Range For A 8.5 Carat Radiant Cut Diamond Ring

Opting for the appropriate color grade when selecting an 8.5 carat radiant cut diamond ring can lead to considerable cost savings. Instead of splurging on diamonds with D-F grades, it is wise to consider a diamond falling within the G-J range, which still guarantees a mesmerizing piece and allows you to pocket up to $79,800 in addition to any savings achieved through astute clarity decisions.

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

Save over $432,100 on your 8.5 carat radiant cut diamond ring by opting for a lab grown diamond.

Lab-grown diamonds are appealing because they look just like natural diamonds, even though they are made in a lab. What makes them even better is that they are produced in a more sustainable and ethical way. Plus, they are way more affordable than natural diamonds, with a lab-grown diamond costing up to 85% less.

If you ever find yourself in a situation where you have to sell your 8.5 carat radiant cut diamond ring, choosing a lab grown diamond can help you minimize your financial loss.

Opting for the appropriate color grade when selecting an 8.5 carat radiant cut diamond ring can lead to considerable cost savings. Instead of splurging on diamonds with D-F grades, it is wise to consider a diamond falling within the G-J range, which still guarantees a mesmerizing piece and allows you to pocket up to $79,800 in addition to any savings achieved through astute clarity decisions.

Lesson 5 - Carat / Size

When you are looking for your diamond ring, focus your money on the carat size.

Why is Carat Important?

Imagine a diamond ring. What's the most eye-catching aspect? Well, it's definitely the size of that dazzling diamond in the middle. When ladies are asked about their preferences, the number one priority is the size of the main diamond. Therefore, we recommend investing your budget in the carat weight, as it determines the diamond's size.
Watch us compare sizes and help you visualize what you want. 

If you're looking for an 8.5 carat radiant cut diamond ring, choose from this range of carat sizes.

It's a wise choice to consider diamonds in the 7.65 to 9.35 carat range. This way, you'll find a good variety of prices without having to go for a much bigger size.

Lesson 6 - Cut

When purchasing your 8.5 carat radiant cut diamond ring, keep in mind that the cut of the diamond determines its sparkle and shine. Opt for an ideal or excellent cut to enhance its beauty.

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

What is Cut?

When you're searching for a remarkable 8.5 carat radiant cut diamond ring, one crucial aspect to think about is the diamond's cut. The cut refers to how precisely and flawlessly the facets of the diamond have been shaped, ultimately impacting its sparkle and brilliance. We can say that the cut plays a vital role in determining the overall beauty of the diamond.

A hidden truth within the diamond industry

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.

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 8.5 carat radiant cut diamond ring.

What is Diamond Shape?

Diamonds come in different shapes, such as round, oval, or radiant. Each shape has its own style and can give a diamond a different look. Some shapes make the diamond appear bigger, while others make it sparkle more and have a classic, timeless charm. You can find a wide range of 8.5 carat diamond rings with various shapes in this section. Use our shape tool to explore and discover the perfect shape for you.

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 an 8.5 carat diamond ring with a radiant cut can be dramatically changed by the band it is paired with.

What is setting?

The shiny part of the diamond ring, which is called the band, is what we call the setting. Typically, these are made from gold and come in different colors like white, yellow, or pink gold. You also have the option to choose a platinum band. The setting is very important in determining the overall look of your 8.5 carat radiant cut diamond ring. This is your chance to add your personal style. We have listed the three most popular settings for you. No matter which one you choose, it's important to always go with 14k gold. As you keep reading, you will 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 an important rule to remember. Avoid using 18k or 24k gold for your jewelry setting. Instead, go for 14k gold. Even though 18k and 24k gold are purer, they are much softer and more prone to bending. If the band holding your precious diamond bends easily, there is a much higher risk of the diamond falling off. This is a problem that many people commonly experience.

Solitaire Choice - A Delicate Band Makes the Diamond Stand Out

According to polling, a sizeable diamond is on most women's wish list. Enhance the visual impact of a 8.5 carat radiant cut diamond ring with a Solitaire setting that features a slender, delicate band. The contrast between the smaller band and the grand diamond can simulate the appearance of a larger stone. For an additional effect, opt for settings that use tiny accent diamonds along the band, adding to the ring's beauty without pulling focus from the centerpiece diamond.

Halo: Increase the size of your diamond by surrounding it with tiny gems.

To make your 8.5 carat radiant cut diamond ring look absolutely stunning, you might want to think about using a halo setting. This technique involves surrounding your main stone with smaller diamonds, which really brings out its brilliance and gives the illusion of a bigger size. And if you really want to take it to the next level, a double halo setting will do just that. Combined with a thin band, this type of setting can make even a smaller diamond appear much grander, giving off a vibe of pure luxury.

The main diamond should be the focal point.

Most women prefer a big diamond. If your ring is too fancy or wide, it might make the diamond look smaller. If the main thing you care about is the 8.5 carat radiant cut diamond ring, a simpler band would be better. However, if you care more about the overall design of the ring, a fancier band might be the right choice, but remember that it could take attention away from the diamond.
