Lesson 2 - Clarity

When shopping for a 1 carat marquise diamond ring, the clarity of the diamond plays a major role in determining its price.

⊗ Up to $7,096 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

Clarity in diamonds refers to how easily you can see the imperfections. The important thing to note is that most of these flaws can only be seen under a 10x magnifying glass. The diamond clarity scale ranges from 'flawless' (FL) to 'included' (I), with grades like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included) in between. Diamonds with these clarity grades usually have imperfections that are only visible under 10x magnification, so they will appear perfectly clear to the naked eye. This ensures that anyone admiring your ring won't notice any flaws!

Optimal Clarity Range for a 1 carat marquise diamond ring

Opting for a diamond in the VS2-SI1 clarity range can bring considerable savings, potentially as much as $7,096 off the total price of your 1 carat marquise diamond ring . We highly recommend VS2 for its balance of price and clarity. Nonetheless, don't overlook SI1 diamonds - with a few minutes of sifting through diamonds, you can find ones that appear virtually 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 cost of a 1 carat marquise diamond ring is greatly affected by the color of the diamond you select.

⊗ Up to $1,490 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 be completely colorless. The Gemological Institute of America (GIA) categorizes them on a scale from D (colorless) to Z (yellow or brown). Most diamonds used in jewelry have a slight color, falling within the G-H range. Any faint traces of color can only be noticed when compared to higher-grade diamonds like D, E, or F. While color becomes more noticeable in larger diamonds, a marquise diamond in the G-H range will appear almost colorless and cost less than a D-grade diamond, which is completely colorless.

Optimal Color Range For A 1 Carat Marquise Diamond Ring

When it comes to a 1 carat marquise diamond ring, opting for the right color grade can lead to significant cost reductions. Instead of paying hefty prices for diamonds with D-F grades, it's worth considering a diamond within the G-J range. This decision can still result in an exquisite piece while saving you up to $1,490, in addition to any savings made through smart choices regarding clarity. In the case of more complex designs like a halo diamond ring, which features 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 noticeable color contrast that may arise when comparing I-J graded diamonds to the smaller, typically colorless or near-colorless diamonds in the halo.

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

Save Up to $3,600 on Your 1 Carat Marquise Diamond Ring with Lab Grown Diamonds.

Lab-grown diamonds, made through artificial means, possess identical visual characteristics to their naturally occurring counterparts, yet they are produced in a manner that is more environmentally friendly and morally sound. Moreover, their enhanced accessibility offers a more economical option, as a lab-grown diamond can be up to 85% less expensive than a similar naturally formed diamond.

Opting for a lab-grown diamond can minimize your financial loss when selling your 1 carat marquise diamond ring.

When it comes to a 1 carat marquise diamond ring, opting for the right color grade can lead to significant cost reductions. Instead of paying hefty prices for diamonds with D-F grades, it's worth considering a diamond within the G-J range.

Lesson 5 - Carat / Size

When you're shopping for your diamond ring, the carat should be your main budget consideration.

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. 

Choose this Carat Range when Purchasing a 1 carat marquise diamond ring.

We recommend that you check out diamonds ranging from 0.9 to 1.1 carats. This will give you a nice selection of prices without a significant increase in size.

Lesson 6 - Cut

The sparkle of a diamond is determined by its cut. For your 1 carat marquise diamond ring, it's recommended to choose either an ideal or excellent cut for maximum brilliance.

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

What is Cut?

When searching for a stunning 1 carat marquise diamond ring, it's important to take into account the diamond's cut. The cut refers to how the facets of the diamond have been shaped, ultimately impacting its sparkle and brilliance. So, the precision and perfection of the cut play a significant role in determining the overall appeal of the diamond.

The closely guarded secret within the diamond industry.

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 brilliance of diamonds is influenced by their shape, and specific shapes can contribute to the perceived value of a 1 carat marquise diamond ring.

What is Diamond Shape?

The diamond's shape determines its style. Examples of different shapes include round, oval, and marquise, among others. Each shape has its own unique qualities: some make the diamond appear larger, some make it sparkle more, and some are considered timeless. In this section, you can use our shape tool to explore a variety of 1 carat diamond rings with different shapes.

What shape to choose?

It's a fact that certain diamond shapes can create the illusion of a larger stone, and currently, some shapes are seen as more fashionable. But when you're deciding, keep in mind that what really counts is what catches your eye and brings you the most joy. If you're unsure and don't have a specific preference, you might want to think about a brilliant cut diamond. This includes shapes like Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant. While Round is the most popular choice, Oval and Marquise shapes can give the diamond a bigger appearance with the same carat weight.

Lesson 8 - Setting

Changing the band of a 1 carat marquise diamond ring can greatly alter its overall look.

What is setting?

Commonly known as the band, the setting is the metal part of the diamond ring. It is typically made of gold, and you can choose from white, yellow, or rose gold options. Another option is a platinum band. The setting plays a crucial role in the overall look of your 1 carat marquise diamond ring. It's where you can showcase your personal style. We have listed the top three settings for you to consider. Regardless of the setting you choose, it is recommended to go with 14k gold. Keep reading to learn more about why this is the preferred choice.
The setting or band is really important for making your diamond look bigger and better. 

If you're looking for the best option, go with a 14K gold band.

Here's a crucial rule to follow. Avoid choosing 18k or 24k gold for your setting. It's better to opt for 14k gold. Despite 18k and 24k gold being more pure, they are considerably softer and prone to bending. If the setting that secures your valuable diamond bends excessively, the chance of the diamond becoming loose and falling out rises significantly. Numerous individuals have faced this issue.

Solitaire Setting - A Slim Band Accentuates the Look of a Larger Diamond

Based on survey data, many women aspire to have a large diamond. To maximize the apparent size of a 1 carat marquise 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: Increase the size of your diamond by surrounding it with tiny gems.

Looking to enhance the appearance of your 1 carat marquise diamond ring? Consider a halo setting. This style features smaller diamonds surrounding the main gem, giving off a radiant effect that makes the diamond appear larger. For an even greater impact, you might want to go for a double halo setting. When combined with a slender band, this setting can create the illusion of a much larger diamond, making it seem like a more extravagant piece.

The main diamond should be the focal point.

Many women desire their diamond to have a stunning look. A band that is overly ornate or wide may draw attention away from the diamond, making it appear smaller. If you want to highlight your 1 carat marquise diamond ring, it would be wise to choose a more straightforward band that doesn't overshadow the stone. However, if the overall design of the ring is more important to you, a intricate band could be a great match, but keep in mind that it may diminish the diamond's standout quality.
