Lesson 2 - Clarity

The cost of a 0.75 carat oval diamond ring is greatly influenced by the clarity of the diamond.

⊗ Up to $54,966 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

In America, clarity refers to the presence of noticeable flaws in a diamond. But it's important to note that these flaws are usually only visible when using a 10x magnifying glass. Diamond clarity is categorized from 'flawless' to 'included'. In between, there are classifications like VS1, VS2, and SI1. These diamonds may have flaws that can only be seen with 10x magnification. To the naked eye, they look completely clear, so nobody will notice any imperfections when they admire your ring!

Optimal Clarity Range for a 6.5 carat radiant cut diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 6.5 carat radiant cut diamond ring can result in significant savings, potentially reducing the total price by as much as $54,966. We strongly suggest considering the VS2 clarity grade due to its optimal combination of price and clarity. However, it is important not to dismiss SI1 diamonds entirely. By investing a few minutes in examining different diamonds, you may come across SI1 diamonds that appear nearly 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.

Lesson 3 - Color

When shopping for a 6.5 carat radiant cut diamond ring, the color of the diamond is another important factor that affects the price.

⊗ Up to $43,820 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can come in a yellowish hue or have no color at all. The GIA categorizes them from D (no color) to Z (yellow or brown). Most diamonds used in jewelry have a slight color, falling within the G-H range. You can only notice faint color differences when comparing them to higher-grade diamonds like D, E, or F. While color becomes more noticeable in larger diamonds, a diamond in the G-H range will still look almost colorless and be less expensive than a D-grade diamond, which is colorless.

Optimal Color Range For A 6.5 Carat Radiant Cut Diamond Ring

When selecting a 6.5 carat radiant cut diamond ring, it's important to carefully consider the color grade. Instead of opting for diamonds in the premium color range of D-F, choosing a diamond in the G-J range can lead to significant savings. By making this choice, you can still acquire a breathtaking piece and potentially save up to $43,820, in addition to any savings achieved through wise decisions 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 $142,000 when opting for a lab grown diamond for your 6.5 carat radiant cut diamond ring.

Lab-grown diamonds, also referred to as man-made diamonds, offer the benefit of having the same appearance as natural diamonds, but they are produced in a way that is more environmentally friendly and morally conscious. Moreover, lab-grown diamonds are more easily accessible compared to natural diamonds, resulting in much more affordable prices. In fact, a lab-grown diamond can be as much as 85% less expensive than a similar natural diamond.

Opting for a lab-grown diamond when selling your 6.5 carat radiant cut ring can reduce your financial loss.

When selecting a 6.5 carat radiant cut diamond ring, it's important to carefully consider the color grade. Instead of opting for diamonds in the premium color range of D-F, choosing a diamond in the G-J range can lead to significant savings. By making this choice, you can still acquire a breathtaking piece and potentially save up to $43,820, in addition to any savings achieved through wise decisions regarding 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. 

Choose this carat range when searching for a radiant cut diamond ring that is 6.5 carats.

It's a smart idea to check out diamonds between 5.85 and 7.15 carats. This way, you can get a feel for the various price ranges without sacrificing much in terms of size.

Lesson 6 - Cut

Always consider the cut of the diamond as it determines its sparkle. When buying your 6.5 carat radiant cut diamond ring, go for an ideal or excellent cut.

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

What is Cut?

Are you in search of the most beautiful 6.5 carat radiant cut diamond ring? Keep in mind that it's all about the way the diamond is cut - the flawless and exact facets - that decide how it sparkles and shines.

The behind-the-scenes truth about diamonds

When talking about diamond cuts, you'd think that an 'Ideal' cut diamond, which is made to give off maximum sparkle with its perfect proportions, would always be the priciest. But sometimes, a 'Fair' cut diamond with the same carat, color, and clarity can actually cost more. It might seem strange, but badly cut diamonds can appear larger while lacking that desired sparkle and brilliance. A diamond without sparkle is like a movie without sound.

Keep this in mind: go for GIA Certified Excellent Cut Diamonds (sometimes referred to as "Ideal" Cut).

Regardless, excellent cut diamonds have incredible sparkle.

Lesson 7 - Shape

The level of sparkle in diamonds depends on their shape, and some shapes can create the impression of a pricier 6.5 carat radiant cut diamond ring.

What is Diamond Shape?

The diamond shape signifies the style of the diamond, such as round, oval, or radiant. There are various shapes that can make a diamond appear larger, while some shapes add more sparkle and give it a timeless, classic look. In this section, you can utilize our shape tool to explore a range of 6.5 carat diamond rings showcasing diverse shapes.

What shape to choose?

Some of these shapes will indeed give the diamond the appearance of being larger, and there are certain shapes that are considered trendy. However, at the end of the day, the most important factor in making this decision should be what catches your attention and brings you the most joy. If you don't have a preference, then I would suggest going for a brilliant cut diamond, which includes shapes such as Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant. Out of these, Round is the most commonly chosen shape. On the other hand, if you want the diamond to appear larger for the same carat weight, then Oval and Marquise shapes would be the way to go.

Lesson 8 - Setting

The band can really change the appearance of a 6.5 carat radiant cut diamond ring.

What is setting?

The part of a diamond ring that holds the diamond, which is called the band, is made of gold. It can be white, yellow, or rose gold. Another option is a band made of platinum. The way the diamond is set on the band plays a big role in how the ring looks overall, especially for a 6.5 carat radiant cut diamond ring. This is your chance to show off your personal style. There are three popular settings that I'll explain below. No matter which setting you like, always go for 14k gold. I'll explain why as you keep reading.
The setting or band is really important for making your diamond look bigger and better. 

Your band ought to be made of 14 karat gold.

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 - A Delicate Ring Enhances the Size of the Center Diamond Significantly

In surveys, most women express a desire for a large diamond. To visually enlarge a 6.5 carat radiant cut diamond ring, think about using a Solitaire setting with a narrow, elegant band. The contrast between the modest band and the sizeable diamond can create the illusion of an even larger stone. Accent diamonds along the band can further enhance this impression, adding a touch of charm without overshadowing the primary diamond.

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

If you're looking for a bigger-looking diamond ring that's 6.5 carats, you should give the halo setting a try. This setting surrounds the main diamond with smaller ones, which adds both radiance and makes it look larger. If you want an even bigger illusion, you might want to consider the double halo setting. When you pair it with a thin band, even a small diamond can appear much larger, giving off a grander ring impression.

Stay focused on the main diamond

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 6.5 carat radiant cut diamond ring to stand out, a simpler band would be a good option. However, if you value the ring's overall design more, a more intricate band could be the better choice. Just keep in mind that this might distract from the diamond's impressive appearance.
