Lesson 2 - Clarity

When searching for a 0.2 carat diamond ring, keep in mind that the clarity of the diamond is what determines its price the most.

⊗ Up to $8,362 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 important to mention that these flaws are usually only visible when using 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 blemishes when they admire your ring!

Optimal Clarity Range for a 2.5 carat marquise diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 2.5 carat marquise diamond ring can result in significant savings, potentially reducing the total price by as much as $8,362. When it comes to striking a balance between price and clarity, we highly recommend opting for a VS2 diamond. However, it is important not to disregard SI1 diamonds. By investing just a few minutes in carefully examining different diamonds, you can easily find ones that give the appearance of being flawlessly 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 shopping for a 2.5 carat marquise diamond ring, the color of the diamond is another important factor that affects the price.

⊗ Up to $12,276 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can have a slight yellow tint or be completely colorless. The GIA grades them on a scale from D (colorless) to Z (yellow or brown). When it comes to jewelry, diamonds typically have a subtle color and fall within the G-H range. You can only really see these faint color differences when comparing them to higher grade diamonds like D, E, or F. The variation in color is more noticeable in larger diamonds. However, even a marquise diamond in the G-H range will appear almost colorless and be less costly than a completely colorless diamond, such as one with a D-grade.

Optimal Color Range For A 2.5 Carat Marquise Diamond Ring

Selecting the appropriate color grade for a 2.5 carat marquise diamond ring can lead to significant cost reductions. Rather than paying premium prices for diamonds graded D-F, it is recommended to opt for a diamond within the G-J range. This decision can still result in a breathtaking piece while potentially saving you up to $12,276, in addition to any savings achieved through wise choices regarding clarity.

Lesson 5 - Carat / Size

When you're shopping for your diamond ring, make sure to consider 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. 

Use this carat range as a guide for a 2.5 carat marquise diamond ring.

You might want to consider checking out diamonds that are between 2.25 and 2.75 carats. This will give you a good idea of various price options without a big jump in size.

Lesson 6 - Cut

Always consider the cut of the diamond as it determines its sparkle. When buying your 2.5 carat marquise diamond ring, go for 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.

Sometimes, people think that the fanciest cut diamond, perfectly proportioned to shine the brightest, would cost the most money. But that's not always true. Believe it or not, there are times when a diamond with an average cut, but with the same weight, color, and clarity, can be sold for a higher price. It may sound strange, but poorly cut diamonds can actually look bigger, yet they lack that special sparkle and brilliance. And let's face it, a diamond without sparkle is like having a computer without a screen.

Here's a crucial tip: always opt for GIA Certified Excellent Cut Diamonds (also known as "Ideal" Cut).

Lesson 7 - Shape

Some diamond shapes are more sparkly & some make 2.5 carat marquise diamond rings look more expensive.

What is Diamond Shape?

When we discuss the diamond shape, we're talking about the style of the diamond, such as round, oval, or marquise. There are actually many different shapes to choose from, each offering its own unique characteristics. Certain shapes can create the illusion of a larger diamond, while others add extra sparkle and a classic charm. If you're interested, take a look at our shape tool in this section. It gives you the opportunity to explore a range of 2.5 carat diamond rings, each featuring a different shape.

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

Changing the band can completely change how a 2.5 carat marquise diamond ring looks.

What is setting?

The metal component of the diamond ring, commonly known as the band, is called the setting. These are typically made of gold and are offered in white, yellow, or rose gold hues. Another option to contemplate for the band is platinum. The setting plays a crucial role in determining the overall look of your 2.5 carat marquise diamond ring. It provides an opportunity to showcase your individual style. We have provided information on the three most popular settings below. Regardless of your preference, it is advisable to select 14k gold. Keep reading to learn the reasons behind this recommendation.
The setting or band is really important for making your diamond look bigger and better. 

Choose a 14K gold 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 Setting - A Slim Band Accentuates the Look of a Larger Diamond

Many women, when surveyed, prefer a large diamond. To emphasize the size of a 2.5 carat marquise 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 Diamond Look Bigger with Lots of Smaller Diamonds

Looking to make your 2.5 carat marquise diamond ring appear bigger? Well, a halo setting could be just what you need. By surrounding the main gem with smaller diamonds, this setting creates a dazzling effect that gives the illusion of a larger diamond. If you really want to make a statement, go for a double halo setting. When combined with a slim band, it can make even a smaller diamond look much grander, giving off a more extravagant vibe.

The main diamond should be the focal point.

Many women like a big diamond. If the band is too fancy or wide, it can make the diamond look smaller. If you want your 2.5 carat marquise diamond ring to be the main attraction, go for a plain band that won't overshadow it. But if the overall design of the ring matters more to you, a more decorative band might suit your taste. Just remember, it might take away from the diamond's standout quality.
