Lesson 2 - Clarity

When looking to purchase a 0.25 carat diamond ring, keep in mind that the clarity of the diamond is the biggest influencer of its cost.

⊗ Up to $71,301 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

When we talk about the clarity of a diamond, we're actually referring to how visible any imperfections are. However, the main focus should be on "visibility" since most of these flaws can only be seen when magnified 10 times. In the diamond industry, clarity is measured on a scale ranging from 'flawless' (FL) to 'included' (I), with categories like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included) falling in the middle. The imperfections in diamonds within these grades are typically only noticeable when viewed through a 10x magnifying glass, which means they appear completely clear to the naked eye. So, anyone admiring your ring won't be able to see them!

Optimal Clarity Range for a 3 carat marquise diamond ring

Choosing a diamond within the VS2-SI1 clarity range for your 3 carat marquise diamond ring can result in substantial savings, potentially reducing the total price by as much as $71,301. When considering the best clarity option, we strongly suggest opting for VS2 due to its favorable combination of price and clarity. However, it is important not to dismiss SI1 diamonds entirely, as with a brief examination of available options, you can easily discover diamonds that possess an almost 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

The cost of a 3 carat marquise diamond ring is greatly affected by the color of the diamond you choose.

⊗ Up to $10,759 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 3 Carat Marquise Diamond Ring

Choosing the appropriate color grade for a 3 carat marquise diamond ring can lead to significant cost savings. Rather than paying premium prices for diamonds with a color grade of D-F, it is advisable to consider selecting a diamond within the G-J range. This decision can still result in a breathtaking piece while potentially saving you up to $10,759, in addition to any savings achieved through sensible choices regarding clarity.

Lab-grown diamonds are appealing because they look just like natural diamonds, even though they are made in a lab.

Plus, they are way more affordable than natural diamonds, with a lab-grown diamond costing up to 85% less.

Opting for a lab-grown diamond can minimize your financial loss when selling your 3 carat marquise diamond ring.

Lesson 5 - Carat / Size

When buying your diamond ring, make sure to prioritize spending on carat.

Why is Carat Important?

Think about a diamond ring for a second. What's the first thing that comes to mind? Of course, it's the size of the main diamond. In surveys, women consistently prioritize the size of the diamond as their main concern. And since carat weight determines the size of the diamond, we suggest you allocate a majority of your budget towards that.
Watch us compare sizes and help you visualize what you want. 

Which carat range should I consider when shopping for a 3 carat marquise diamond ring?

You should check out diamonds that range from 2.7 to 3.3 carats. That way, you'll get a good sense of the price difference without a significant change in size.

Lesson 6 - Cut

The cut of a diamond is what gives it that special sparkle. When buying your 3 carat marquise diamond ring, make sure to choose an ideal or excellent cut.

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

What is Cut?

When you're looking for a remarkable diamond, you have to consider the cut. The cut is extremely important in determining the quality of the diamond's sparkle and brilliance because it involves the precise shaping of all the facets.

A little-known secret within the world of diamonds.

When talking about diamond cuts, you'd think that an 'Ideal' cut diamond, which is made to give off maximum sparkle with its perfect proportions, would always be the priciest. But sometimes, a 'Fair' cut diamond with the same carat, color, and clarity can actually cost more. It might seem strange, but badly cut diamonds can appear larger while lacking that desired sparkle and brilliance. A diamond without sparkle is like a movie without sound.

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

Lesson 7 - Shape

When selecting diamonds, keep in mind that different shapes offer distinct levels of sparkle, and certain shapes can create the illusion of a pricier 3 carat marquise diamond ring.

What is Diamond Shape?

The way the diamond is shaped determines its style, like being round, oval, or marquise. There are various shapes that can make a diamond appear bigger, make it shine more, or give it a classic and classy look. Take a look at our shape tool in this section to find a wide selection of 3 carat diamond rings in different shapes.

What shape to choose?

It's important to recognize that certain diamond cuts can give off the illusion of a bigger gem, and there are some cuts that are currently in style. Nevertheless, the most important decision is the one that truly speaks to you. If you're unsure about which cut to go for, think about getting a brilliant cut diamond. This includes shapes like Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant. Out of all these options, Round diamonds are the ones that get chosen most frequently, while Oval and Marquise cuts can make a diamond look bigger without increasing the carat weight.

Lesson 8 - Setting

The appearance of a 3 carat marquise diamond ring can vary significantly depending on the band it is paired with.

What is setting?

The metal part of a diamond ring, which people commonly call the band, is actually called the setting. These settings are usually made of gold and come in different colors like white, yellow, or rose. There's also the option of a platinum band. The setting plays a huge role in how your 3 carat marquise diamond ring looks overall. It's a great way to showcase your personal style. The three most popular settings are listed below. Regardless of which one you choose, we suggest sticking with 14k gold. We'll explain why as you keep reading.
The setting or band is really important for making your diamond look bigger and better. 

Choose a 14K gold band.

This is a really important rule to keep in mind. Avoid using 18k or 24k gold for your jewelry setting. Instead, go for 14k gold. It's important to mention that even though 18k and 24k gold are purer, they're much easier to bend and reshape. If the setting holding your precious diamond is too flexible, there's a much higher chance of the diamond falling out. It's a common problem that many people have experienced.

Solitaire Choice - A Delicate Band Makes the Diamond Stand Out

Most women, based on surveys, lean towards a larger diamond. To bring out the size of a 3 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 the Appearance of Your Diamond with Smaller Stones Around It

For a bigger-looking 3 carat marquise diamond ring, you can go for the halo setting. This setting circles the main diamond with smaller ones, which makes it shine brightly and seem larger. If you want an even greater illusion, you should check out the double halo setting. When paired with a thin band, it can make even a small diamond look much bigger, giving off the impression of a more extravagant ring.

Maintain the Main Diamond's Dominance

Many ladies prefer a diamond that appears large. If your ring's band is too fancy or wide, it may distract from the diamond and make it seem smaller. If you want to highlight your 3 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, then an intricate band might be what you want. Just keep in mind that this could diminish the diamond's sparkle.
