Lesson 2 - Clarity

If you're looking to buy a 0.9 carat radiant cut diamond ring, the clarity of the diamond is the primary factor that affects its cost.

⊗ Up to $5,570 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 0.9 carat radiant cut diamond ring

By choosing a diamond in the VS2-SI1 clarity range for your 0.9 carat radiant cut diamond ring, you can save a significant amount, up to $5,570 off the overall price. 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 moments spent browsing through the available options, you can easily find SI1 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

When looking for a 0.9 carat radiant cut diamond ring, the diamond's color has a big impact on its price.

⊗ Up to $809 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can either have a yellowish tint or be completely colorless. The Gemological Institute of America (GIA) categorizes diamonds based on their color, ranging from D (colorless) to Z (yellow or brown). Most diamonds used in jewelry have a slight color, falling within the G-H range. Only when compared to higher-grade diamonds like D, E, or F can you notice any faint traces of color. Although color becomes more noticeable in larger diamonds, a radiant diamond in the G-H range will still appear almost colorless and will be more affordable compared to a D-grade diamond, which is completely colorless.

Optimal Color Range For A 0.9 Carat Radiant Cut Diamond Ring

Selecting a 0.9 carat radiant cut diamond ring with the appropriate color grade can lead to significant cost savings. Instead of paying premium prices for diamonds graded D-F, it is recommended to opt for diamonds in the G-J range. By making this choice, you can still acquire an exquisite piece while potentially saving up to $809, in addition to any savings resulting from astute decisions regarding clarity. When it comes to more intricate designs, such as a halo diamond ring featuring numerous smaller diamonds surrounding the central stone, it is advisable to choose a central diamond in the G-H color range. This approach helps ensure a lack of noticeable color contrast that might arise when comparing I-J graded diamonds to the smaller diamonds in the halo, which are typically colorless or near-colorless.

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 $2,200 on your 0.9 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 find yourself needing to sell your 0.9 carat radiant cut diamond ring, choosing a lab grown diamond can help mitigate your financial loss.

Selecting a 0.9 carat radiant cut diamond ring with the appropriate color grade can lead to significant cost savings.

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?

Imagine a diamond ring. What's the main attraction? The size of the center diamond, of course. It's no secret - women agree that size is important according to surveys. And since the carat weight determines the size of the diamond, that's where we suggest you spend your money.
Watch us compare sizes and help you visualize what you want. 

Choosing the Carat Range for Shopping for a 0.9 carat radiant cut diamond ring

It would be smart to check out diamonds between 0.81 and 0.99 carats. This way, you can get an idea of the various prices without sacrificing much in terms of size.

Lesson 6 - Cut

When purchasing your 0.9 carat radiant cut diamond ring, remember that the cut of the diamond determines how it sparkles. Opt for an ideal or excellent cut for the most brilliant stone.

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

What is Cut?

The secret behind a stunning 0.9 carat radiant cut diamond ring lies in the diamond's cut. It's all about how flawlessly and meticulously the diamond's facets have been crafted, directly impacting its overall shine and beauty.

What diamond companies don't want you to know

You may think that the most expensive diamond is always the one with the perfect cut, designed to dazzle with maximum sparkle. However, that's not always the case. Surprisingly, a diamond with a "Fair" cut, but with the same carat, color, and clarity, can actually cost more. It may sound odd, but diamonds that are poorly cut can give off the impression of being larger, while lacking the sparkle and brilliance that you crave. A diamond without sparkle is like a book without any words.

One last thing to keep in mind: go for GIA Certified Excellent Cut Diamonds (also known as "Ideal" Cut).

Lesson 7 - Shape

Consider a diamond's shape since it can impact the sparkle of a 0.9 carat radiant cut diamond ring, making it seem more expensive.

What is Diamond Shape?

The shape of a diamond determines its style, and there are various shapes to choose from, including round, oval, and radiant, among others. Different shapes can create the illusion of a bigger diamond and provide more sparkle, giving it a classic and timeless appearance. Take a look at our shape tool in this section, where you can find a wide selection of 0.9 carat diamond rings with a range of shapes to explore.

What shape to choose?

When it comes to choosing a diamond, some shapes can make it look bigger, and certain shapes are trendy right now. But what really matters is what you personally love and what brings you joy. If you can't decide, go for a brilliant cut diamond, which includes shapes like Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant. Round is the most popular, but Oval and Marquise have the power to make the diamond look larger even with the same weight.

Lesson 8 - Setting

Changing the band of a 0.9 carat radiant cut diamond ring can completely change how it looks.

What is setting?

The shiny part of a diamond ring that holds the stone is called the setting. It is typically made of gold in different colors like white, yellow, or rose. You can also choose to have a band made of platinum. The setting plays a vital role in how your 0.9 carat radiant cut diamond ring looks. It allows you to showcase your own unique style. Here, we've listed the three most commonly chosen settings. No matter which one you choose, it's recommended to go for 14k gold. Keep reading to find out why.
The setting or band is really important for making your diamond look bigger and better. 

You should choose a 14K Gold band.

Always keep in mind this important advice. Avoid choosing 18k or 24k gold for your setting. Opt for 14k gold instead. Even though 18k and 24k gold are more pure, they are much softer and more prone to bending. If the setting that holds your precious diamond bends, there is a higher chance of the diamond coming loose and falling out. This is a problem that is commonly encountered.

Solitaire Ring - A Thin Band Makes Your Diamond Appear Bigger.

Survey data indicates that a large diamond is a common desire among women. To visually enhance the size of a 0.9 carat radiant 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: Give Your Diamond the Illusion of Size with a Bunch of Smaller Ones

To make your 0.9 carat radiant cut diamond ring look more stunning, you might want to think about using a halo setting. This technique involves placing smaller diamonds around the main stone, which enhances its sparkle and gives the illusion of a bigger diamond. If you go for a double halo setting, it takes this effect to the next level. When paired with a slim band, this setting can make even a tiny diamond appear much larger, creating a sense of luxury for the entire piece.

Maintain the Main Diamond's Dominance

Most women prefer a big diamond. If your ring is very flashy or wide, it might take attention away from the diamond, making it appear smaller. If you really care about having a 0.9 carat radiant cut diamond ring, a simpler band would be a good choice. On the other hand, if the overall design of the ring matters more to you, a fancier band could be the right option. Just remember, this might shift the focus away from the diamond.
