Lesson 2 - Clarity

When shopping for a 0.5 carat radiant cut diamond ring, the clarity of the diamond is the most important aspect to keep in mind regarding its price.

⊗ Up to $1,692 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

The clarity of a diamond is a term used to describe how visible its imperfections are. However, it's important to remember that "visible" typically means visible when looking at the diamond through a 10x magnifying glass. The clarity scale goes from 'flawless' (FL) to 'included' (I), and there are also grades in between like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included). Diamonds in these categories often have imperfections that can only be seen under 10x magnification. Therefore, to the naked eye, they will generally appear completely clear, making sure your ring looks flawless to everyone who sees it!

Optimal Clarity Range for a 0.5 carat radiant cut diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 0.5 carat radiant cut diamond ring can result in significant savings, potentially reducing the total price by as much as $1,692. When it comes to price and clarity, we highly recommend opting for a VS2 diamond. However, it is worth noting that SI1 diamonds should not be disregarded. With just a few minutes spent sifting through diamonds, you can easily find SI1 stones that appear almost 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.

While some may not live up to your expectations, there are many that are absolutely stunning and could even be mistaken for a higher quality VS2 diamond.

Lesson 3 - Color

The color of a diamond is a major factor in determining the price of a 0.5 carat radiant cut diamond ring.

⊗ Up to $287 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. While larger diamonds may show more noticeable color, a radiant diamond in the G-H category will still appear nearly colorless and be less expensive than a D-grade diamond, which is completely colorless.

Optimal Color Range For A 0.5 Carat Radiant Cut Diamond Ring

Selecting the appropriate color grade for a 0.5 carat radiant cut diamond ring can lead to significant cost savings. Instead of splurging on diamonds graded D-F, consider opting for a diamond within the G-J range. By doing so, not only can you still obtain a breathtaking piece, but you could also save up to $287, in addition to any savings achieved through wise decisions regarding clarity. When it comes to intricate designs like a halo diamond ring comprised of numerous smaller diamonds encircling the main stone, it is recommended to choose a central diamond falling within the G-H color range. This tactic helps avert any noticeable color contrast that might arise when comparing I-J graded diamonds to the smaller, generally colorless or nearly colorless diamonds within the halo.

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 $800 on your 0.5 carat radiant cut diamond ring with a lab grown diamond.

Lab-grown diamonds, also called lab-created diamonds, possess an indistinguishable look from genuine diamonds but are manufactured in a more environmentally friendly and morally conscious process. Additionally, they offer a greater affordability owing to their increased accessibility compared to natural diamonds. In fact, a lab-grown diamond can be up to 85% cheaper than a similar natural diamond.

If you ever decide to part ways with your 0.5 carat radiant cut diamond ring, choosing a lab-grown diamond can help minimize your financial loss.

Selecting the appropriate color grade for a 0.5 carat radiant cut diamond ring can lead to significant cost savings. Instead of splurging on diamonds graded D-F, consider opting for a diamond within the G-J range. By doing so, not only can you still obtain a breathtaking piece, but you could also save up to $287, in addition to any savings achieved through wise decisions regarding clarity. When it comes to intricate designs like a halo diamond ring comprised of numerous smaller diamonds encircling the main stone, it is recommended to choose a central diamond falling within the G-H color range.

Lesson 5 - Carat / Size

When you're shopping for your diamond ring, make sure to consider the carat weight.

Why is Carat Important?

Take a moment to consider a diamond ring. The first thing that catches your eye is the size of the sparkling center diamond, isn't it? Well, for women, it's the same thing. They prioritize size above anything else. That's why when it comes to carat weight, which directly affects the size of the diamond, we suggest, "That's where you should allocate your budget!"
Watch us compare sizes and help you visualize what you want. 

Choose this carat range when purchasing a 0.5 carat radiant cut diamond ring.

We suggest checking out diamonds that are between 0.45 and 0.55 carats. This will give you an idea of different prices without a significant increase in size.

Lesson 6 - Cut

The sparkle of a diamond is determined by its cut. For your 0.5 carat radiant cut diamond ring, it's recommended to choose either an ideal or excellent cut for maximum brilliance.

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

What is Cut?

To find a truly impressive radiant cut diamond ring weighing 0.5 carats, you must focus on its cut. This pertains to the skillful and meticulous shaping of the diamond's facets, which affects its overall brilliance and shimmer.

The diamond companies well-kept secret

You might think that an 'Ideal' cut diamond, which is crafted to give maximum sparkle by having perfect proportions, would be the priciest option. However, that is not always true. Sometimes, a 'Fair' cut diamond with similar carat, color, and clarity can have a higher price tag. It may seem confusing, but diamonds that are poorly cut can actually look bigger while lacking the desired sparkle and brilliance. A diamond without sparkle is comparable to a phone with no signal.

Here's a valuable tip: always opt for GIA Certified Excellent Cut Diamonds (also known as "Ideal" Cut).

Lesson 7 - Shape

Not all diamond shapes are equally sparkly; some shapes can give the illusion of a higher cost in 0.5 carat radiant cut diamond rings.

What is Diamond Shape?

The shape of a diamond determines its style, like round, oval, or radiant. Different shapes can make a diamond appear bigger, while others accentuate its sparkle and capture timeless beauty. You can use our shape tool in this section to discover a range of 0.5 carat diamond rings featuring various shapes.

What shape to choose?

Sure, some diamond shapes can make the stone look bigger, and some shapes are popular right now. But remember, what really counts is what makes you the happiest. If you're not sure, a brilliant cut diamond, such as Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant shapes, might be your best bet. Out of these, Round diamonds are the most popular, while Oval and Marquise shapes can give the impression of a larger diamond without weighing more.

Lesson 8 - Setting

The band of a 0.5 carat radiant cut diamond ring can have a significant impact on its overall appearance.

What is setting?

The shiny part of a diamond ring that holds the stone, often called the band, is called the setting. These are typically made of gold in different colors like white, yellow, or pink. Alternatively, you can choose a band made of platinum. The setting plays a crucial role in the overall beauty of your 0.5 carat radiant cut diamond ring. It allows you to showcase your own unique style. Below, we have listed the top three settings that are currently in high demand. No matter which setting you choose, it's always recommended to go for 14k gold. Continue reading to find out why this is the preferred choice.
The setting or band is really important for making your diamond look bigger and better. 

It's always best to go with 14K Gold when selecting your ring band.

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 Style - A Sleek Band Makes the Diamond Appear Bigger

According to surveys, most women want a really big diamond. A ring with a slim and dainty single band can make a 0.5 carat radiant cut diamond look even bigger. The contrast between the small band and the large diamond makes it seem like the diamond is even larger than it actually is. Adding small accent diamonds in the band can enhance this effect, giving it a touch of sophistication without taking away from the main diamond.

Halo: Make Your Diamond Look Bigger with a Bunch of Smaller Stones

If you want to make your 0.5 carat radiant cut diamond ring look bigger, you might consider a halo setting. This style involves placing smaller diamonds around the main gem, which makes it appear brighter and larger. To enhance this effect even more, you can opt for a double halo setting. When combined with a thin band, this can create the illusion of a much larger diamond, giving off a sense of luxurious extravagance.

The main diamond should be the focal point.

Many women desire a diamond that looks big and full. A band that is overly fancy or wide might take away attention from the diamond, making it seem smaller. If you want to emphasize your 0.5 carat radiant cut diamond ring, a simpler band would be a good option. However, if you value the overall design of the ring, a more detailed band could be the perfect choice for you. Just remember, this might diminish the diamond's standout feature.
