Lesson 2 - Clarity

When shopping for a 0.5 carat round diamond ring, the clarity of the diamond plays a major role in determining its price.

⊗ Up to $1,609 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

Diamond clarity refers to how many imperfections a diamond has that can be seen. However, when we say "detectable," we mostly mean that these flaws can only be seen with a 10x magnifying lens. Clarity in diamonds ranges from 'flawless' (FL) to 'included' (I), with classifications in between like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included). These diamonds usually have imperfections that can only be seen with a 10x magnifying glass, so they will appear perfectly clear to the naked eye - meaning nobody will notice any flaws when they look at your ring!

Optimal Clarity Range for a 0.5 carat round diamond ring

By selecting a diamond in the VS2-SI1 clarity range, you have the opportunity to save a significant amount, up to $1,609, on your purchase of a 0.5 carat round diamond ring. It is strongly advised to consider the VS2 clarity grade due to its favorable combination of price and clarity. However, it is important not to disregard SI1 diamonds either. With just a few minutes dedicated to examining various diamonds, it is possible to discover ones that possess 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.

Lesson 3 - Color

The cost of a 0.5 carat round diamond ring is heavily impacted by the chosen diamond's color.

⊗ Up to $249 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can come in various shades, ranging from yellowish to completely colorless. The Gemological Institute of America (GIA) ranks diamonds on a scale from D (colorless) to Z (yellow or brown). Most jewelry diamonds have a slight amount of color and fall into the G-H category. These subtle color differences can only be detected when comparing them to higher-graded diamonds like D, E, or F. Although larger diamonds may show more noticeable color, a round diamond in the G-H category will still appear nearly colorless and will be less expensive than a D-grade diamond, which is completely colorless.

Optimal Color Range For A 0.5 Carat Round Diamond Ring

Choosing the appropriate color grade for a 0.5 carat round diamond ring can lead to significant cost reductions. Instead of paying high prices for diamonds graded D-F, consider opting for a diamond in the G-J range. This decision can still result in a stunning piece, allowing you to save up to $249 along with any additional savings achieved through smart clarity choices. When it comes to more intricate designs like a halo diamond ring adorned with numerous smaller diamonds encircling the main stone, it is recommended to select a central diamond falling within the G-H color range. This approach helps avoid any noticeable color contrast that may arise when comparing the I-J graded diamonds to the smaller diamonds in the halo, which are typically colorless or nearly 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 up to $600 on your 0.5 carat round diamond ring by opting for a lab grown diamond.

Lab-grown diamonds are incredibly attractive because they look just like natural diamonds, even though they are made in a lab. What makes them even more appealing is that the way they are produced is environmentally friendly and morally responsible. On top of that, lab-grown diamonds are significantly more affordable than natural diamonds, with prices that can be up to 85% lower.

If you find yourself in a situation where you have to sell your 0.5 carat round diamond ring, choosing a lab-grown diamond can help you minimize the financial impact.

Choosing the appropriate color grade for a 0.5 carat round diamond ring can lead to significant cost reductions. Instead of paying high prices for diamonds graded D-F, consider opting for a diamond in the G-J range. This decision can still result in a stunning piece, allowing you to save up to $249 along with any additional savings achieved through smart clarity choices. When it comes to more intricate designs like a halo diamond ring adorned with numerous smaller diamonds encircling the main stone, it is recommended to select a central diamond falling within the G-H color range. This approach helps avoid any noticeable color contrast that may arise when comparing the I-J graded diamonds to the smaller diamonds in the halo, which are typically colorless or nearly colorless.

Lesson 5 - Carat / Size

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

Why is Carat Important?

Picture a diamond ring. The size of the central diamond really catches your attention, doesn't it? Well, surveys indicate that women concur - it's the most crucial aspect. The higher the carat, the larger the diamond, and that's where we suggest you invest your funds.
Watch us compare sizes and help you visualize what you want. 

If you're looking for a 0.5 carat round diamond ring, choose a ring within this carat range.

It would be a good idea to check out diamonds in the 0.45 to 0.55 carat range. This way, you can get an idea of the various price ranges without much variation in size.

Lesson 6 - Cut

The cut of a diamond is what gives it that special sparkle. When buying your 0.5 carat round 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?

When searching for a stunning 0.5 carat round diamond ring, it's important to keep in mind that the way the diamond is cut plays a significant role. The cut essentially refers to the precise shaping of all the diamond's facets, which has a direct impact on its overall shine and beauty.

The closely guarded secret within the diamond industry.

In some cases, the belief that an 'Ideal' cut diamond, which is famous for its flawless sparkle, must always be the most expensive is not necessarily accurate. It's actually surprising that a 'Fair' cut diamond with the same carat, color, and clarity can sometimes cost even more. It may sound strange, but diamonds that are poorly cut can appear larger while lacking the desired sparkle and brilliance. It's like having a guitar without strings when you have a diamond without any sparkle.

One last thing to keep in mind: go for GIA Certified Excellent Cut Diamonds (also known 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 0.5 carat round diamond ring.

What is Diamond Shape?

When we mention the diamond shape, we're referring to the way the diamond is cut, like round, oval, and other variations. Some shapes can give the diamond a larger appearance, while others provide more radiance and a timeless allure. Take a look at our shape tool in this section to explore a range of 0.5 carat diamond rings featuring various shapes.

What shape to choose?

When you're thinking about diamond shapes, it's a fact that certain shapes can give the stone a bigger look, and there are shapes that are currently popular in the market. But what really counts is the shape that speaks to your heart. If you're looking for some guidance, a brilliant cut diamond might be just what you need. This includes shapes like Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant. Out of these choices, Round diamonds are the most commonly loved, while Oval and Marquise shapes can make the diamond look larger even with the same carat weight.

Lesson 8 - Setting

A half-carat round diamond ring can look completely different depending on the band it's paired with, thanks to the band's influence.

What is setting?

The shiny part of the diamond ring, known as the band, is what we call the setting. Usually, these are made of gold and come in different colors like white, yellow, or pink gold. You can also choose a platinum band if you prefer. The setting plays a big role in how the 0.5 carat round diamond ring looks overall. It's your chance to add your own personal style. We have listed the three most popular settings for you. No matter which one you choose, it's best to go with 14k gold. As you keep reading, you'll understand why this is the case.
The setting or band is really important for making your diamond look bigger and better. 

Think about getting a 14K gold band for your ring.

Remember this important guideline. Don't use 18 karat or 24 karat gold for your setting. Go with 14 karat gold instead. Even though 18 karat and 24 karat gold are more pure, they are noticeably less durable and prone to bending. If your precious diamond's setting bends too easily, there's a significant risk of the diamond becoming loose and falling out. This is a common problem for many people.

Solitaire - A Thinner Band to Make the Diamond Look Larger

A lot of women, when asked, like a big diamond. If you want to make a 0.5 carat round diamond ring look bigger, you can go for a slim, dainty band with a Solitaire setting. The noticeable difference between the smaller band and the bigger diamond can make it seem like the stone is larger than it actually is. Additional diamonds along the band can enhance this effect, adding decorative elements without taking away attention from the main diamond.

Halo: Boost Your Diamond's Volume with Many Small Gems

The halo setting provides an extra way to make your 0.5 carat round diamond ring seem bigger. By surrounding the main diamond with smaller ones, it creates a dazzling effect that enhances the size of the central diamond. If you want to make the illusion even more impressive, you can choose a double halo setting. When combined with a slim band, this can make a smaller diamond appear much larger, giving the impression of a more luxurious piece.

Don't diminish the significance of the main diamond.

A lot of ladies are attracted to a diamond that looks really large. If the band is too fancy or wide, it might take away attention from the diamond, making it seem smaller. If you want to show off your 0.5 carat round diamond ring, think about choosing a simple band that won't overshadow it. On the other hand, if the overall design of the ring is more appealing to you, a band with intricate details might match your style, but keep in mind that it could diminish the diamond's main attraction.
