Lesson 2 - Clarity

If you're considering buying a 0.9 carat marquise diamond ring, the clarity of the diamond is the most crucial element to consider in terms of pricing.

⊗ Up to $4,341 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 the presence of noticeable flaws. It's worth mentioning that these flaws are usually only visible when you look at the diamond through a 10x magnifying glass. Diamond clarity is categorized from "flawless" to "included". In the middle, you'll come across classifications like VS1, VS2, and SI1. These diamonds may have imperfections that can only be seen with 10x magnification. To the naked eye, they look absolutely flawless, so nobody will be able to notice any imperfections when they admire your ring!

Optimal Clarity Range for a 0.9 carat marquise diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 0.9 carat marquise diamond ring can result in significant savings, with the potential to reduce the total price by as much as $4,341. When considering the balance between price and clarity, we strongly suggest opting for a VS2 diamond. However, it is important not to disregard SI1 diamonds, as with just a few minutes of searching through the available options, you can discover diamonds that appear 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 looking for a marquise diamond ring that weighs 0.9 carats, the color of the diamond has a significant impact on its price.

⊗ Up to $1,176 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can have a yellow 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 little color and fall in the G-H group. Only when compared to higher-ranked diamonds like D, E, or F, can you see slight traces of color. Even though color is more noticeable in larger diamonds, a marquise diamond in the G-H group will still appear almost colorless and won't be as costly as completely colorless diamonds with a D-grade.

Optimal Color Range For A 0.9 Carat Marquise Diamond Ring

Choosing the right color grade for a 0.9 carat marquise diamond ring can lead to significant savings. Instead of paying premium prices for D-F graded diamonds, consider opting for a diamond within the G-J range. This decision can still result in a breathtaking piece while saving you up to $1,176 in addition to any savings made from wise choices regarding clarity.

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 over $2,700 on your 0.9 carat marquise diamond ring by opting for a lab grown diamond.

Lab-grown diamonds are appealing because they look just like natural diamonds, even though they are made in a lab. What makes them even better is that they are produced in a more sustainable and ethical way. Plus, they are way more affordable than natural diamonds, with a lab-grown diamond costing up to 85% less.

Lesson 5 - Carat / Size

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

Why is Carat Important?

Take a moment to consider a diamond ring. The first thing that catches your eye is the size of the sparkling center diamond, isn't it? Well, for women, it's the same thing. They prioritize size above anything else. That's why when it comes to carat weight, which directly affects the size of the diamond, we suggest, "That's where you should allocate your budget!"
Watch us compare sizes and help you visualize what you want. 

The Best Carat Range for shopping a 0.9 carat marquise diamond ring.

It would be smart to check out diamonds between 0.81 and 0.99 carats. This way, you can get an idea of the various prices without sacrificing much in terms of size.

Lesson 6 - Cut

The sparkle of a diamond is determined by its cut. For your 0.9 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?

If you want to find an absolutely amazing marquise diamond ring that weighs 0.9 carats, you gotta take a good look at how it's cut. The cut of a diamond is all about how the facets are shaped to make it shine and sparkle like crazy.

What diamond companies don't want you to know

An 'Ideal' cut diamond is famous for its maximum sparkle due to its perfectly proportioned cut, and it's usually thought to be the most expensive. However, there are instances when a 'Fair' cut diamond, with the same carat, color, and clarity, can actually be more costly. It might seem confusing, but poorly cut diamonds can appear larger without providing the desired sparkle and brilliance. A diamond lacking sparkle is comparable to a garden without soil.

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 0.9 carat marquise diamond ring.

What is Diamond Shape?

The shape of a diamond determines its style, whether it's round, oval, marquise, or many others. Different shapes can make a diamond appear bigger, shine brighter, or offer a classic appeal. Take a look at our shape tool in this section to explore a range of 0.9 carat diamond rings with various shapes.

What shape to choose?

When thinking about diamond shapes, it's important to know that some can give the illusion of a bigger stone, and there are shapes that are currently in demand. However, at the end of the day, your choice should be based on what you truly love. If you don't have a strong preference, you might want to consider a brilliant cut diamond, which includes shapes like Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant. Out of these options, Round diamonds are the most popularly chosen, but you might find that Oval and Marquise shapes can make the diamond appear larger even with the same weight in carats.

Lesson 8 - Setting

The band can greatly change the look of a 0.9 carat marquise diamond ring.

What is setting?

The part of the diamond ring that is made of metal, which is often called the band, is actually called the setting. These settings 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 0.9 carat marquise diamond ring. It's an opportunity for you to show off your personal style. We have listed the three most popular choices for settings below. Whatever you choose, it's always a good idea to go with 14k gold. Keep reading to find out 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.

Keep in mind this important rule. Avoid using 18k or 24k gold for your setting. Instead, go for 14k gold. Even though 18k and 24k gold have a higher purity, they are very soft and likely to bend. If the setting that holds your valuable diamond bends easily, there's a high chance that the diamond will fall out. This is a common problem faced by many people.

Solitaire Choice - A Delicate Band Makes the Diamond Stand Out

Poll results indicate that most women have a preference for large diamonds. A way to highlight the size of a 0.9 carat marquise diamond ring is by choosing a Solitaire setting with a fine, delicate band. The difference in size between the tiny band and the large diamond can generate an illusion of an even bigger stone. Adding small accent diamonds along the band can also amplify this effect, providing decorative detail without overshadowing the central diamond.

Halo: Enhance the Appearance of Your Diamond by Encircling It with Smaller Ones

Looking to enhance the size of your 0.9 carat marquise diamond ring? You might want to consider the halo setting. With this style, smaller diamonds encircle the main stone, giving off a radiant effect and making your diamond appear bigger. And for an even more impressive look, you could try the double halo setting. Coupled with a slim band, this technique can make any smaller diamond seem larger, providing a sense of luxury.

Make sure to focus on the main diamond.

Many ladies desire a diamond that looks impressive. A band that is overly ornate or wide could take attention away from the diamond, making it appear smaller. If displaying your 0.9 carat marquise diamond ring is your main goal, choosing a simpler band that doesn't overshadow the stone would be wise. However, if the overall design of the ring is more important to you, a detailed band might be a great choice, but keep in mind that it could diminish the diamond's exceptional quality.
