Lesson 2 - Clarity

When shopping for a 0.5 carat marquise diamond ring, the diamond's clarity is the major factor that affects its pricing.

⊗ Up to $1,454 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, we're basically talking about any imperfections in a diamond. However, it's important to emphasize that most of these flaws can only be seen when the diamond is magnified 10 times. The terms "Flawless" (FL) and "included" (I) are used to describe the range of diamond clarity. But you'll also come across terms like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included). These grades indicate that there may be some defects in the diamond, but they can only be seen with a 10x magnifying glass. To the naked eye, these diamonds usually look perfect, so no one will notice any flaws when they admire your ring!

Optimal Clarity Range for a 0.5 carat marquise diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 0.5 carat marquise diamond ring can lead to substantial savings, potentially reducing the total price by as much as $1,454. For its combination of price and clarity, we strongly suggest considering a VS2 diamond. However, it is important not to dismiss SI1 diamonds altogether. With just a few minutes of searching through diamonds, you can discover SI1 diamonds that have 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 marquise diamond ring weighing 0.5 carats is greatly affected by the color of the diamond you choose.

⊗ Up to $376 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can come in shades of yellow or be completely colorless. The Gemological Institute of America (GIA) rates diamonds on a scale from D (colorless) to Z (yellow or brown). Most diamonds used in jewelry have a slight tint and fall within the G-H range. The subtle hints of color in these diamonds can only be noticed when compared to higher-grade diamonds like D, E, or F. Although larger diamonds may show more noticeable color, a marquise diamond in the G-H range will still appear almost colorless and will be less expensive than completely colorless diamonds like those in the D-grade.

Optimal Color Range For A 0.5 Carat Marquise Diamond Ring

Selecting the appropriate color grade for a 0.5 carat marquise diamond ring can lead to significant cost reductions. Instead of paying premium prices for diamonds graded D-F, consider opting for diamonds within the G-J range. This decision can still result in a breathtaking piece while saving you up to $376, in addition to any savings gained from making well-informed choices regarding clarity. Furthermore, when it comes to intricate designs like a halo diamond ring with numerous smaller diamonds encircling the main stone, it is advisable to choose a central diamond in the G-H color range. By doing so, you can avoid any noticeable color contrast that may arise when comparing I-J graded diamonds to the smaller, typically colorless or near-colorless diamonds in the halo.

Lesson 4 - Lab Grown

Discover How Lab Grown Diamonds Can Help You Save $1,200 on Your 0.5 Carat Marquise Diamond Ring.

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 needing to sell your 0.5 carat marquise diamond ring, choosing a lab-grown diamond can mitigate your financial loss.

Lesson 5 - Carat / Size

When buying your diamond ring, make sure to prioritize spending on carat.

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. 

If you're looking for a 0.5 carat marquise diamond ring, go with this carat range.

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 cut of a diamond is what gives it that beautiful sparkle. For your 0.5 carat marquise diamond ring, make sure to choose either 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 you're looking for the most stunning half-carat marquise diamond ring, remember that the way it's cut plays a big role in how it shines and sparkles. The cut refers to how precisely and perfectly the diamond's angles are shaped.

A hidden truth within the diamond industry

An "Ideal" cut diamond is the one that is perfectly proportioned to give off the most sparkle. People usually assume that it would be the most expensive. However, it's not always the case. Sometimes, a "Fair" cut diamond with the same carat, color, and clarity can actually cost more than an "Ideal" cut. It may seem confusing, but the reason behind it is that a poorly cut diamond often appears larger, but it lacks the brilliance and sparkle that you desire. Imagine a diamond without any sparkle - it's like a house without a solid foundation.

Last but not least, make sure to go for GIA Certified Excellent Cut Diamonds (sometimes referred to as "Ideal" Cut).

Lesson 7 - Shape

The sparkle of a diamond can vary based on its shape, and certain shapes can make 0.5 carat marquise diamond rings appear more expensive.

What is Diamond Shape?

The diamond shape is all about the style of the diamond, which includes round, oval, and marquise. Some shapes can make the diamond look bigger, while others give it more sparkle and a classic look. Take a look at our shape tool in this section to see a variety of 0.5 carat diamond rings with various shapes.

What shape to choose?

Certain diamond shapes can create the impression of being bigger, and there are some shapes that are currently popular. However, what truly matters is what you personally find attractive and fulfilling. If you are unsure, a brilliant cut diamond encompassing Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant shapes could be a fantastic option. Among these, Round is the most commonly preferred shape, but Oval and Marquise shapes can make the diamond seem larger even with the same carat weight.

Lesson 8 - Setting

The appearance of a 0.5 carat marquise diamond ring can completely change with a different band.

What is setting?

The part of the diamond ring that is made of gold, 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 rose gold. You can also choose a platinum band if you prefer. The setting plays a significant role in how your 0.5 carat marquise diamond ring looks. This is your chance to add your personal style to it. We have listed the three most popular settings for you. No matter which one you choose, it is important to go with 14k gold. As you continue reading, you will understand why this is the best choice.
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.

Here's an important rule to remember: try not to choose 18k or 24k gold for your setting. Your safest option is 14k gold. Even though 18k and 24k gold are purer, they are noticeably softer and more likely to bend. If the band holding your precious diamond can easily bend, there's a big chance that the diamond might come loose. This is a problem that many people often face.

Solitaire Choice - A Delicate Band Makes the Diamond Stand Out

According to survey results, lots of women desire to own a big diamond. If you want to make a 0.5 carat marquise diamond ring look larger, opt for a Solitaire setting with a thin and elegant band. The difference between the smaller band and the bigger diamond can create the illusion of a larger stone. To enhance this effect, search for settings that have small accent diamonds on the band. These will add a classy detail without diverting focus from the main diamond.

Halo: Use smaller diamonds to make your diamond look bigger.

Choosing a halo setting is a clever choice to make your 0.5 carat marquise diamond ring appear larger. This type of setting involves smaller diamonds surrounding the main stone, creating a shiny effect that enhances the perceived size of the diamond. If you're looking to go above and beyond, pairing a double halo setting with a slim band can make even a small diamond appear much bigger, giving the impression of a more extravagant ring.

Keep the focus on the main diamond.

Most women prefer their diamond to look big. A fancy or wide band might make the diamond seem smaller. If you want your 0.5 carat marquise diamond ring to stand out, a simpler band would be a good option. However, if you care more about the ring's overall design, a more intricate band could be a better choice, but keep in mind that it might take away from the diamond's eye-catching look.
