Lesson 2 - Clarity

The pricing of a 0.75 carat pear shaped diamond ring is primarily 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 the world of diamonds, clarity refers to how flawless they appear. However, it's important to note that the term "noticeable" is key here, as most imperfections can only be seen under a 10x magnifying glass. Diamond clarity is categorized from 'flawless' (FL) to 'included' (I), with classifications like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included) falling in between. Diamonds in these categories often have blemishes that can only be seen with a 10x magnifier. So, to the naked eye, they usually look completely clear, ensuring that anyone admiring your ring won't notice any flaws!

Optimal Clarity Range for a 6.5 carat round diamond ring

Choosing a diamond in the VS2-SI1 clarity range can result in significant savings, potentially reducing the total price of your 6.5 carat round diamond ring by up to $54,966. We strongly suggest considering a VS2 diamond due to its excellent balance between price and clarity. However, it is important not to disregard SI1 diamonds. By dedicating a few minutes to browse through diamonds, you can discover SI1 diamonds that exhibit 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.

Lesson 3 - Color

When looking for a round diamond ring that weighs 6.5 carats, the diamond's color has a significant impact on its 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 have a yellowish tint or no color. The Gemological Institute of America (GIA) ranks diamond color from D (colorless) to Z (yellow or brown). Most jewelry diamonds have minimal color and fall in the G-H range. Only when compared to higher-ranked diamonds like D, E, or F, can you detect slight traces of color. Although color is more noticeable in larger diamonds, those in the G-H range still appear almost colorless and are less costly than completely colorless diamonds like those with a D-grade.

Optimal Color Range For A 6.5 Carat Round Diamond Ring

Opting for a 6.5 carat round diamond ring calls for careful consideration of the color grade, as it can lead to significant cost savings. Instead of paying exorbitant prices for diamonds graded D-F, it would be wise to opt for a diamond in the G-J range. By making this choice, you can still acquire a breathtaking piece while also saving up to $43,820, in addition to any savings attained through clever decisions regarding clarity.

Lesson 4 - Lab Grown
Save up to 85% on your diamond ring.

Save up to $142,000 on your 6.5 carat round diamond ring when opting for a lab grown diamond.

Lab-grown diamonds, also known as man-made diamonds, possess the benefit of appearing identical to natural diamonds, while being created through a sustainable and ethical process. Moreover, their affordability is enhanced due to their increased availability compared to natural diamonds. In fact, a lab-grown diamond can cost up to 85% less than a similar natural diamond.

Consider opting for a lab-grown diamond when selling your 6.5 carat round diamond ring to minimize your financial loss.

Opting for a 6.5 carat round diamond ring calls for careful consideration of the color grade, as it can lead to significant cost savings.

Lesson 5 - Carat / Size

When you're shopping for a diamond ring, prioritize investing in the carat weight.

Why is Carat Important?

Picture a diamond ring. The size of the central diamond really catches your attention, doesn't it? Well, surveys indicate that women concur - it's the most crucial aspect. The higher the carat, the larger the diamond, and that's where we suggest you invest your funds.
Watch us compare sizes and help you visualize what you want. 

When shopping for a round diamond ring with a 6.5 carat, consider selecting from this range of carats.

We recommend looking at diamonds that are between 5.85 and 7.15 carats. This way, you can find a variety of prices without a significant jump in size.

Lesson 6 - Cut

When buying your 6.5 carat round 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?

Looking for the most stunning 6.5 carat round diamond ring? The way the diamond is cut plays a big role in its sparkle and brilliance. It's all about how precisely and flawlessly every facet is shaped.

The diamond companies well-kept secret

Although people usually assume that an 'Ideal' cut diamond, which is perfectly proportioned for maximum sparkle, would be the most expensive, there are cases where a 'Fair' cut diamond with similar carat, color, and clarity can actually be pricier. This might sound strange, but diamonds that are poorly cut can appear larger even though they lack the desired sparkle and brilliance. A diamond without sparkle is similar to a puzzle without pieces.

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

Lesson 7 - Shape

The sparkliness of diamonds varies depending on their shape, and some shapes can add to the perceived value of a 6.5 carat round diamond ring.

What is Diamond Shape?

Shape is what gives a diamond its unique style, like round, oval, or even round. There are actually many different shapes out there to choose from. Certain shapes have a way of making a diamond look bigger than it actually is, while others make it sparkle more and give it a classic appeal. Take a look at our shape tool in this section and you'll find a range of 6.5 carat diamond rings with all sorts of shapes to suit your taste.

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 appearance of a 6.5 carat round diamond ring can completely change when paired with a different band.

What is setting?

The band, also referred to as the part that holds the diamond, is the metal component of the ring. It is typically made from gold and comes in different shades like white, yellow, or rose gold. Platinum is also available as an alternative for the band. The setting plays a crucial role in determining the overall appearance of your 6.5 carat round diamond ring. It gives you a chance to showcase your personal taste. We have listed the top three most popular settings below. Regardless of your choice, we recommend sticking with 14k gold. Continue reading to understand why.
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 a really important tip. Avoid choosing between 18 karat or 24 karat gold for your setting. It's better to go with 14 karat gold instead. Even though 18 karat and 24 karat gold are more pure, they are much softer and prone to bending easily. If the setting of your valuable diamond bends too easily, it greatly raises the risk of the diamond slipping out. Many people have faced this issue before.

Solitaire - A Great Band for a Flashier Diamond Presentation

Many women, when surveyed, prefer a large diamond. To emphasize the size of a 6.5 carat round 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: Make Your Diamond Look Bigger with a Bunch of Smaller Stones

If you want your 6.5 carat round diamond ring to appear bigger, a halo setting could be just what you need. With this arrangement, smaller diamonds encircle the main gem, enhancing its brilliance and making it seem larger. You can enhance this effect even more with a double halo setting. When combined with a thin band, this can create the illusion of a much larger diamond, giving off a sense of luxurious opulence.

Do not overshadow the main diamond.

Many women prefer a diamond that looks big. A band that is too detailed or wide might take attention away from the diamond, making it seem smaller by comparison. If you want your 6.5 carat round diamond ring to be the main focus, you might consider selecting a simpler band that won't overpower it. However, if the overall design of the ring is more significant to you, a more intricate band might be your preference, but remember, it could affect the diamond's standout factor.
