Lesson 2 - Clarity

When shopping for a 0.3 carat oval diamond ring, the diamond's clarity is the key factor that affects its pricing.

⊗ Up to $30,968 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 3.5 carat radiant cut diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 3.5 carat radiant cut diamond ring can result in significant savings, potentially reducing the total price by as much as $30,968. We strongly suggest considering a diamond with a VS2 clarity grade due to its favorable combination of price and clarity. However, it is important not to disregard SI1 diamonds. With just a few moments spent examining different diamonds, you can discover SI1 stones 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.

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

When looking for a 3.5 carat radiant cut diamond ring, the diamond's color has a significant impact on its price.

⊗ Up to $19,808 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can come in different shades, ranging from slightly yellowish to completely clear. The Gemological Institute of America (GIA) rates them on a scale from D (no color) to Z (yellow or brown). When it comes to jewelry, diamonds usually have a slight hint of color and fall within the G-H range. The subtle traces of color in these diamonds can only be detected when compared to higher-grade ones like D, E, or F. While smaller diamonds may not show as much color, larger ones in the G-H range, like a radiant cut, will still appear almost colorless. Additionally, they will be less expensive than a D-grade diamond, which is completely colorless.

Optimal Color Range For A 3.5 Carat Radiant Cut Diamond Ring

Opting for the ideal color grade when purchasing a 3.5 carat radiant cut diamond ring can lead to significant savings. Instead of splurging on diamonds graded D-F, contemplate selecting one within the G-J range. By doing so, not only can you still acquire an exquisite piece, but you could also pocket as much as $19,808 in savings, in addition to any prudent decisions made concerning 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 $49,700 on your 3.5 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 sell your 3.5 carat radiant cut diamond ring, choosing a lab grown diamond can help reduce your financial loss.

Opting for the ideal color grade when purchasing a 3.5 carat radiant cut diamond ring can lead to significant savings. Instead of splurging on diamonds graded D-F, contemplate selecting one within the G-J range. By doing so, not only can you still acquire an exquisite piece, but you could also pocket as much as $19,808 in savings, in addition to any prudent decisions made concerning clarity.

Lesson 5 - Carat / Size

When searching for your diamond ring, the main factor to consider is the carat size.

Why is Carat Important?

Imagine a diamond ring for a moment. What stands out the most? It's definitely the size of the main diamond! Women agree on this - surveys show that size is the most important factor. That's why our budget recommendation is straightforward: pay attention to the carat weight, which directly determines the size.
Watch us compare sizes and help you visualize what you want. 

Here are the carat options you should consider when looking for a radiant cut diamond ring that is 3.5 carats.

We recommend that you check out diamonds ranging from 3.15 to 3.85 carats. This will give you a variety of prices without a significant increase in size.

Lesson 6 - Cut

When buying your 3.5 carat radiant cut diamond ring, remember that the cut of the diamond is what gives it that brilliant sparkle. Stick to ideal or excellent cut options.

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

What is Cut?

When searching for a stunning 3.5 carat radiant cut diamond ring, it's important to carefully consider the diamond's cut. The cut refers to how each facet of the diamond has been shaped, ultimately affecting its sparkle and brilliance. This aspect plays a crucial role in determining the overall beauty and appeal of the diamond.

The closely guarded secret within the diamond industry.

You might think that a diamond with an 'Ideal' cut, which has perfect proportions and sparkles the most, would be the most expensive. But that's not always true. Sometimes, a 'Fair' cut diamond with the same carat, color, and clarity can actually cost more. It might sound strange, but poorly cut diamonds can look bigger while lacking the sparkle and brilliance you want. A diamond without sparkle is basically a cake without frosting.

Remember this final advice: stick with GIA Certified Excellent Cut Diamonds (commonly called "Ideal" Cut).

Lesson 7 - Shape

The sparkle of a diamond can vary based on its shape, and certain shapes can make 3.5 carat radiant cut diamond rings appear more expensive.

What is Diamond Shape?

The diamond's style is determined by its shape, like round, oval, or radiant. There are many more shapes to choose from that can make a diamond look bigger, enhance its sparkle, or keep its classic charm. Take a look at our shape tool in this section to find a variety of 3.5 carat diamond rings with different 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 band can really change the appearance of a 3.5 carat radiant cut diamond ring.

What is setting?

The shiny part of the diamond ring, also called 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 band made of platinum. The setting is important in determining how the whole 3.5 carat radiant cut diamond ring looks. This is your chance to add your 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 will understand why this is the case.
The setting or band is really important for making your diamond look bigger and better. 

Try to get 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 Style - A Sleek Band Makes the Diamond Appear Bigger

Based on survey data, many women aspire to have a large diamond. To maximize the apparent size of a 3.5 carat radiant cut diamond ring, consider a Solitaire setting with a slim, refined band. The contrast of the smaller band with the larger diamond can make the stone appear larger. To augment this effect, look for settings that feature small accent diamonds along the band. They'll add a tasteful embellishment without taking attention away from the main diamond.

Halo: Enhance Your Diamond's Size with Small Diamonds

Looking to make your 3.5 carat radiant cut diamond ring appear even more impressive? You should consider a halo setting. This type of setting features smaller diamonds encircling the main gem, which creates a radiant effect and gives the illusion of a larger diamond. If you really want to make a statement, try a double halo setting. Pair it with a thin band and you'll make a smaller diamond look much bigger, giving off the impression of a more extravagant piece.

Maintain the Main Diamond's Dominance

Most women prefer their diamond to look big. A fancy or wide band might take away from the diamond's size, giving it a smaller appearance. If you want your 3.5 carat radiant cut 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 this might diminish the diamond's impressive look.
