Lesson 2 - Clarity

If you're considering buying a 0.75 carat diamond ring, the clarity of the diamond is the most crucial element to consider in terms of pricing.

⊗ 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 the world of diamonds, clarity refers to how flawless they are. However, the interesting part is that these flaws are only visible under a 10x magnifier. The clarity scale ranges from 'flawless' to 'included', with classifications like VS1, VS2, and SI1 in between. Diamonds in these categories usually have imperfections that can only be seen with magnification. So, to the naked eye, they look completely clear, and nobody will notice any flaws when they admire your ring!

Optimal Clarity Range for a 6.5 carat marquise diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 6.5 carat marquise diamond ring can result in significant savings, potentially reducing the total price by as much as $54,966. When considering the clarity options, we strongly suggest selecting a diamond in the VS2 category due to its favorable balance between price and clarity. However, it is important not to disregard SI1 diamonds. With just a few minutes of searching through the available diamonds, you can easily find ones 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

The color of the diamond you choose greatly affects the price of a 6.5 carat marquise diamond ring.

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

What is Color?

Diamonds can vary in color, ranging from yellow to colorless. The Gemological Institute of America (GIA) rates diamonds on a scale from D (colorless) to Z (yellow or brown). The majority of diamonds used in jewelry have a slight color, falling within the G-H range. These subtle color differences are typically only noticeable when compared to higher-grade diamonds like D, E, or F. While color is more noticeable in larger diamonds, a diamond from the G-H range will still appear almost colorless and will be less expensive than a completely colorless diamond, such as a D-grade diamond.

Optimal Color Range For A 6.5 Carat Marquise Diamond Ring

Choosing the right color grade for a 6.5 carat marquise diamond ring can result in significant savings. Instead of paying premium prices for D-F graded diamonds, consider opting for a diamond in the G-J range. This decision can still provide an exquisite piece while saving you up to $43,820, in addition to any savings resulting from making smart choices regarding clarity. For more elaborate designs like a halo diamond ring with numerous smaller diamonds encircling the main stone, it is advisable to select a central diamond in the G-H color range. This approach helps prevent any visible color contrast that may arise when comparing I-J graded diamonds to the smaller, typically colorless or near-colorless diamonds in 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 $142,000 on your 6.5 carat marquise diamond ring with a lab grown diamond.

Lab-grown diamonds, which are created in a lab rather than mined from the earth, have the same visual qualities as diamonds found in nature. They are produced in a more environmentally friendly and ethical manner. Additionally, lab-grown diamonds are more readily available and therefore much more affordable. In fact, the cost of a lab-grown diamond can be up to 85% lower than that of a comparable natural diamond.

If you ever decide to sell your 6.5 carat marquise diamond ring, choosing a lab-grown diamond can help mitigate your financial loss.

Choosing the right color grade for a 6.5 carat marquise diamond ring can result in significant savings. Instead of paying premium prices for D-F graded diamonds, consider opting for a diamond in the G-J range. This decision can still provide an exquisite piece while saving you up to $43,820, in addition to any savings resulting from making smart choices regarding clarity.

Lesson 5 - Carat / Size

Invest more in carat size for a bigger gem in your diamond ring.

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. 

Choose this carat range when purchasing a 6.5-carat marquise diamond ring.

We recommend that you check out diamonds ranging from 5.85 to 7.15 carats. This will give you a nice variety of prices without a significant increase in size.

Lesson 6 - Cut

It's important to understand that the cut of a diamond directly impacts its sparkle. When buying your 6.5 carat marquise diamond ring, choose an ideal or excellent cut to enhance its brilliance.

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

What is Cut?

To discover a truly amazing marquise diamond ring weighing 6.5 carats, it's crucial to focus on its cut. This refers to the accuracy and flawlessness with which the diamond's facets are crafted, affecting its overall brilliance and shine.

The undisclosed secret of diamond companies

You might think that an 'Ideal' cut diamond, which is famous for its perfectly sparkly appearance, is always the most expensive. Well, it turns out that this assumption isn't always accurate. Surprisingly enough, a 'Fair' cut diamond with the same carat, color, and clarity can sometimes be even pricier. It might sound strange, but poorly cut diamonds can actually appear larger while lacking that desired sparkle and brilliance. A diamond without any sparkle is just like a guitar without any strings.

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

Lesson 7 - Shape

The sparkle of a diamond can vary based on its shape, and certain shapes can make 6.5 carat marquise diamond rings appear more expensive.

What is Diamond Shape?

The style of a diamond is determined by its shape, which can be round, oval, marquise, and many more. Each shape has its own unique qualities, some can make a diamond appear bigger and others can make it sparkle more, giving it a classic look. To explore a wide range of 6.5 carat diamond rings with various shapes, check out our shape tool in this section.

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 way a 6.5 carat marquise diamond ring looks.

What is setting?

The metal part of the diamond ring, which is often called the band, is known as the setting. These are typically made of gold and come in white, yellow, or rose gold colors. Another material you might want to consider for the band is platinum. The setting plays a very important role in determining the overall look of your 6.5 carat marquise diamond ring. It's a place where you can add your own personal touch. We have provided the three most popular settings below. Regardless of your preference, it's always recommended to choose 14k gold. Keep reading to find out why.
The setting or band is really important for making your diamond look bigger and better. 

Make sure that the band of your ring is made of 14 karat gold.

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 Style - A Sleek Band Makes the Diamond Appear Bigger

Most women, based on surveys, lean towards a larger diamond. To bring out the size of a 6.5 carat marquise diamond ring, ponder over a Solitaire setting with a thin, fine band. The contrast between the small band and the hefty diamond can give the illusion of a larger stone. Adding petite accent diamonds along the band can add a refined touch without stealing the limelight from the main diamond.

Halo: Enhance Your Diamond's Size with Small Diamonds

The halo setting presents an alternative method to amplify the apparent size of your 6.5 carat marquise diamond ring. By encircling the primary diamond with smaller ones, it generates a luminous impact, giving the impression of a bigger main diamond. To make the optical illusion even more striking, you could select a double halo setting. This, combined with a slender band, can make a smaller diamond appear substantially larger, creating the illusion of a more lavish piece.

Keep the focus on the main diamond.

Many women want a diamond that appears really large. A band that is overly decorative or wide can take away attention from the diamond, making it seem smaller in comparison. If you want your marquise diamond ring, which weighs 6.5 carats, to be a real attention-grabber, it might be a good idea to select a more simple band. However, if you appreciate the overall design of the entire ring, a detailed band could be your preference, but keep in mind that this might lessen the diamond's impressive appearance.
