Lesson 2 - Clarity

The price of a 1.5 carat marquise diamond ring is heavily dependent on the clarity of the diamond.

⊗ Up to $15,049 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 1.5 carat marquise diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 1.5 carat marquise diamond ring can result in significant savings, with the potential to reduce the total price by as much as $15,049. We highly suggest considering the VS2 clarity grade due to its excellent balance of price and clarity. However, it is important not to disregard SI1 diamonds, as with just a few minutes of searching through diamonds, you can discover ones that appear flawlessly beautiful.

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.

However, it's important to understand that not all SI1 diamonds are the same. While some might not meet your expectations, many of them are truly stunning and have a similar look to a VS2 diamond.

Lesson 3 - Color

When looking for a 1.5 carat marquise diamond ring, the diamond's color has a significant impact on its price.

⊗ Up to $4,192 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 1.5 Carat Marquise Diamond Ring

Opting for the appropriate color grade for a 1.5 carat marquise diamond ring can lead to significant cost reductions. Rather than paying premium prices for diamonds graded D-F, consider selecting a diamond within the G-J range. This decision can still deliver a captivating piece while saving you up to $4,192, in addition to any savings made by making astute choices regarding clarity.

Lesson 5 - Carat / Size

If you're purchasing a diamond ring, it's wise to focus on the carat weight as a significant factor to consider for your investment.

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 option for a marquise diamond ring with a weight of 1.5 carats would be this carat range.

We would suggest checking out diamonds that are between 1.35 and 1.65 carats. This way, you can see different prices without a significant increase in size.

Lesson 6 - Cut

When purchasing your 1.5 carat marquise diamond ring, remember that the cut of the diamond determines how it sparkles. Opt for an ideal or excellent cut for the most brilliant stone.

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

What is Cut?

The cut of a 1.5 carat marquise diamond ring is incredibly important if you want it to shine its brightest. The way the diamond is cut and the precision of its facets can greatly enhance its sparkle and brilliance.

What diamond companies don't want you to know

When it comes to diamond cuts, the 'Ideal' cut is often seen as the most valuable since it's designed to make the diamond shine the most with perfect proportions. But, you might be surprised to learn that sometimes a 'Fair' cut diamond, with the same carat, color, and clarity, could actually be pricier. Sounds weird, doesn't it? Well, that's because diamonds that are poorly cut might look bigger but they lack the sparkle and brilliance that you're looking for. A diamond without sparkle is basically like a boat without water.

Don't forget this important tip: always select GIA Certified Excellent Cut Diamonds (often 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 1.5 carat marquise diamond ring.

What is Diamond Shape?

When we discuss the diamond's shape, we're talking about its overall style, such as round, oval, or marquise. Each shape has its own unique qualities that can affect how the diamond appears. Some shapes have a way of making the diamond appear larger, while others add extra sparkle and give a timeless appearance. To explore a range of 1.5 carat diamond rings with different shapes, take a look at our shape tool featured in this section.

What shape to choose?

Sure, some diamond shapes can make the stone look bigger, and some shapes are popular right now. But remember, what really counts is what makes you the happiest. If you're not sure, a brilliant cut diamond, such as Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant shapes, might be your best bet. Out of these, Round diamonds are the most popular, while Oval and Marquise shapes can give the impression of a larger diamond without weighing more.

Lesson 8 - Setting

The appearance of a 1.5 carat marquise diamond ring can completely transform with a new band.

What is setting?

The shiny part of the diamond ring, also called the band, is what we call the setting. Usually, these are made of gold and can come in different colors like white, yellow, or pink gold. You can also choose a platinum band if you prefer. The setting plays a big role in how your 1.5 carat marquise diamond ring looks. This is your chance to add your personal style. We've listed the three most popular settings for you. No matter which one you choose, it's important to go with 14k gold. As you keep reading, you'll understand why this is the best choice.
The setting or band is really important for making your diamond look bigger and better. 

Choose a 14K gold band.

Here's an important rule to keep in mind. Avoid using 18k or 24k gold for your setting. Instead, go for 14k gold. Even though 18k and 24k gold may be more pure, they are much softer and more prone to bending. If the band holding your precious diamond bends easily, there's a much higher risk of the diamond falling off. Many people encounter this problem frequently.

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

Survey data indicates that a large diamond is a common desire among women. To visually enhance the size of a 1.5 carat marquise diamond ring, you could consider a Solitaire setting with a slender, elegant band. The disparity between the slim band and the large diamond can create the illusion of a bigger gem. Further enhance this by incorporating petite accent diamonds along the band—they add a touch of elegance without detracting from the main diamond.

Halo: Give Your Diamond the Illusion of Size with a Bunch of Smaller Ones

If you want to make your 1.5 carat marquise diamond ring appear bigger, you can consider a halo setting as a great option. With this arrangement, smaller diamonds encircle the main stone, making it shine brighter and appear larger. To enhance this effect even more, you can opt for a double halo setting. When combined with a thin band, this can create an illusion of a much larger diamond, giving off a sense of opulent luxury.

Maintain the Main Diamond's Dominance

A lot of ladies prefer a big-looking diamond. If your ring band is too fancy or wide, it might take away attention from the diamond and make it seem smaller. If you want to highlight your 1.5 carat marquise diamond ring, it's better to choose a simple band that won't overshadow it. However, if you find the overall design of the ring more attractive, a fancy band could be what you're after, just keep in mind that it might make the diamond lose some of its sparkle.
