Lesson 2 - Clarity

The pricing of a 0.25 carat oval diamond ring is primarily determined by the clarity of the diamond.

⊗ Up to $15,624 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

In the world of diamonds, clarity refers to how noticeable any imperfections are. The main focus is on how easily these flaws can be seen, as most of them can only be detected with a 10x magnifying tool. A diamond's clarity can range from 'flawless' (FL) to 'included' (I), with various classifications like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included) falling in between. These types of diamonds typically have imperfections that can only be seen under 10x magnification. So, to the naked eye, they will appear completely clear – meaning anyone admiring your ring won't have a clue about any flaws!

Optimal Clarity Range for a 3 carat radiant cut diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 3 carat radiant cut diamond ring can result in significant savings, potentially reducing the total price by as much as $15,624. Considering the balance between price and clarity, we highly suggest opting for a VS2 diamond. However, it is important not to dismiss SI1 diamonds entirely. By investing a few minutes in examining different diamonds, you can find SI1 stones that have a nearly 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.

SI1 - Slightly Included

Cost: $32,787 Total Savings: $7,620 - $11,223 You won't find a better deal on diamond clarity than this one. However, it's important to keep in mind that not all SI1 diamonds are identical in appearance. While some may not meet your specific preferences, many of them are truly breathtaking and could easily be mistaken for a higher quality diamond, like a VS2.

Lesson 3 - Color

The color of the diamond you choose has a big impact on the price of a 3 carat radiant cut diamond ring.

⊗ Up to $12,202 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 3 Carat Radiant Cut Diamond Ring

Opting for a radiant cut diamond ring that weighs 3 carats allows for a brilliant and eye-catching piece. Rather than investing in lower quality diamonds, it is recommended to select a central diamond in the D-F color grade range. This decision ensures a stunning ring while potentially saving you a substantial amount, possibly reaching up to $15,000, in addition to any savings made from judicious choices regarding clarity.

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 $24,900 on your 3 carat radiant cut diamond ring with lab grown diamonds.

Lab-grown diamonds are diamonds that are created in a laboratory setting. These diamonds possess identical visual characteristics to those found in nature but are manufactured in a manner that is more environmentally friendly and morally sound. Additionally, lab-grown diamonds are more budget-friendly because they are more readily accessible than natural diamonds. In fact, a lab-grown diamond can be up to 85% cheaper than a similar diamond found in nature.

If you ever decide to sell your 3 carat radiant cut diamond ring, choosing a lab-grown diamond can help mitigate your financial loss.

Opting for a radiant cut diamond ring that weighs 3 carats allows for a brilliant and eye-catching piece. Rather than investing in lower quality diamonds, it is recommended to select a central diamond in the D-F color grade range. This decision ensures a stunning ring while potentially saving you a substantial amount, possibly reaching up to $15,000, in addition to any savings made from judicious choices regarding clarity.

Lesson 5 - Carat / Size

When you're looking to buy a diamond ring, consider investing in carat.

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. 

Use this carat range as a guide when looking for a 3 carat radiant cut diamond ring.

You should think about looking at diamonds that are between 2.7 and 3.3 carats. This way, you can explore different prices without a big jump in size.

Lesson 6 - Cut

The cut of a diamond is what gives it that special sparkle. When buying your 3 carat radiant cut 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 you're looking for the most stunning 3 carat radiant cut diamond ring, remember that the way it's cut plays a big role in how it sparkles and shines. The cut refers to how perfectly the diamond's angles are shaped.

The undisclosed secret of diamond companies

You might think that the most expensive diamond is always the one with the perfect cut, known as the 'Ideal' cut. But surprisingly, there are cases where a diamond with a 'Fair' cut can be pricier, even if it has the same carat, color, and clarity. It may sound strange, but diamonds that are poorly cut can appear larger while lacking the sparkle and brilliance you're looking for. A diamond without sparkle is like a kite without a string.

Don't forget this important tip: always select GIA Certified Excellent Cut Diamonds (often referred to as "Ideal" Cut).

Lesson 7 - Shape

The brilliance of diamonds is influenced by their shape, and specific shapes can contribute to the perceived value of a 3 carat radiant cut diamond ring.

What is Diamond Shape?

The diamond shape is all about the style of the diamond, which can vary from round to oval and radiant. Different shapes can give the diamond a bigger appearance, while others provide more sparkle and a classic vibe. Check out our shape tool in this section to see a variety of three-carat diamond rings with various shapes.

What shape to choose?

Different diamond shapes can give the illusion of a larger stone, and certain shapes are trendy right now. However, it's important to remember that your personal preference and happiness should be the ultimate deciding factor. If you're unsure about which style to choose, a brilliant cut diamond might be the ideal option. This category includes Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant shapes. Among these, Round diamonds are usually the top choice, but Oval and Marquise shapes have the potential to make the diamond appear larger for the same carat weight.

Lesson 8 - Setting

The band has the ability to transform a 3 carat radiant cut diamond ring into something entirely new.

What is setting?

The part of the diamond ring that's made of metal, known as the band, is called the setting. Usually, it's made of gold and comes in white, yellow, or rose colors. You can also opt for a platinum band. The setting is very important for the overall look of your diamond ring with a 3 carat radiant cut stone. This is where you can show off your own personal style. Below, we've listed the three most popular settings. No matter which setting you pick, we recommend going with 14k gold. Keep reading to find out why we suggest this.
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.

This is a really important rule to keep in mind. Avoid using 18k or 24k gold for your jewelry setting. Instead, go for 14k gold. It's important to mention that even though 18k and 24k gold are purer, they're much easier to bend and reshape. If the setting holding your precious diamond is too flexible, there's a much higher chance of the diamond falling out. It's a common problem that many people have experienced.

Solitaire Choice - A Delicate Band Makes the Diamond Stand Out

Many women, when surveyed, prefer a large diamond. To emphasize the size of a 3 carat radiant cut diamond ring, a thin, delicate band in a Solitaire setting can be considered. The stark contrast between the smaller band and the larger diamond can create an illusion of a larger stone. Accent diamonds along the band can further boost this illusion, providing decorative detail without detracting from the main diamond.

Halo: Enhance the Appearance of Your Diamond by Encircling It with Smaller Ones

A halo setting is a fantastic option to give your 3 carat radiant cut diamond ring a bigger appearance. This setting incorporates smaller diamonds that encircle the main stone, giving it a radiant glow that enhances the size of the central diamond. For an even more substantial illusion, you might want to consider a double halo setting. When paired with a slim band, this setting can create the illusion of a larger diamond, making your piece look even more impressive.

Stay focused on the main diamond

Most women prefer their diamond to look big. A fancy or wide band could take away from the diamond's size, making it seem smaller. If you want your 3 carat radiant cut diamond ring to stand out, a simpler band might be a good option. However, if you care more about the ring's overall design, a more intricate band could be the way to go. Just keep in mind that this may take away from the diamond's standout look.
