Lesson 2 - Clarity

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

⊗ Up to $42,446 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

When we talk about diamond clarity, we're basically checking if the diamond has any noticeable imperfections. But here's the catch - these flaws are usually only visible when you use a 10x magnifying glass. Diamond clarity is categorized from 'flawless' (FL) to 'included' (I), with other categories like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included) falling in between. The flaws in diamonds with these clarity ratings can usually only be seen under 10x magnification. To the naked eye, they will appear crystal clear, so anyone admiring your ring is unlikely to notice anything!

Optimal Clarity Range for a 2.5 carat oval diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 2.5 carat oval diamond ring can result in significant savings, potentially reducing the total price by as much as $42,446. When considering the clarity factor, we highly suggest opting for VS2 diamonds due to their excellent balance between price and clarity. However, it is essential not to disregard SI1 diamonds. By dedicating a few minutes to carefully examine the diamonds, you can discover SI1 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 color of a diamond is a major factor in determining the price of a 2.5 carat oval diamond ring.

⊗ Up to $9,511 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamond color is determined by the presence or absence of a yellow hue. The GIA rates diamond color on a scale from D (no color) to Z (light yellow or brown). When it comes to making jewelry, diamonds that are close to colorless, falling within the G-H range, are typically used. It can be difficult to spot any minor traces of color in these diamonds unless they are compared to higher-graded ones. It's important to note that the differences in diamond color are usually extremely subtle and may go unnoticed by someone without training. However, in larger diamonds, the color may become more noticeable. A diamond within the G-H range, which is almost colorless, will appear that way and be priced more favorably compared to diamonds that are more colorless.

Optimal Color Range For A 2.5 Carat Oval Diamond Ring

For a 2.5 carat oval diamond ring, it is recommended to opt for a diamond in the E-F color range. By choosing a diamond with such color grade, you can prevent any visible color differences that may arise compared to the smaller diamonds surrounding the main stone. Additionally, this decision can result in significant savings, potentially saving you up to $14,250 in combination with any prudent choices made regarding the diamond's clarity.

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

Save Up to $24,500 on Your 2.5 Carat Oval Diamond Ring with Lab Grown Diamonds.

Lab-grown diamonds are the result of scientific processes that create diamonds that appear identical to those found in nature. These lab-grown diamonds are produced in a way that is more environmentally friendly and morally responsible. Compared to naturally occurring diamonds, they are more readily available, making them much more affordable to purchase. In fact, a lab-grown diamond can be up to 85% cheaper than a similar diamond found in nature. The main advantage of lab-grown diamonds is that they offer the opportunity to acquire a diamond of superior quality at a significantly lower cost. This not only reduces the financial burden upfront but also lessens the impact on one's finances, even if selling the diamond later on is not an option.

Having a lab-grown diamond can minimize your financial loss when selling your 2.5 carat oval diamond ring.

For a 2.5 carat oval diamond ring, it is recommended to opt for a diamond in the E-F color range. By choosing a diamond with such color grade, you can prevent any visible color differences that may arise compared to the smaller diamonds surrounding the main stone. Additionally, this decision can result in significant savings, potentially saving you up to $14,250 in combination with any prudent choices made regarding the diamond's clarity.

Lesson 5 - Carat / Size

When searching for a diamond ring, prioritize the carat weight as the main factor to consider when deciding where to allocate your budget.

Why is Carat Important?

Let's discuss diamond rings. What's the first thing that pops into your head? That's right, the size of the large sparkler in the center. When we asked women what was most important, they all agreed on one thing: size matters! The higher the carat weight, the larger the diamond, and that's where we recommend you spend a little extra!
Watch us compare sizes and help you visualize what you want. 

This carat range is the best choice for a 2.5 carat oval diamond ring.

You should check out diamonds that range from 2.25 to 2.75 carats. That way, you'll get a good sense of the price differences without a significant change in size.

Lesson 6 - Cut

The cut of a diamond is what gives it that beautiful sparkle. For your 2.5 carat oval diamond ring, make sure to choose either an ideal or excellent cut.

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

What is Cut?

Looking for the most stunning 2.5 carat oval diamond ring out there? Well, let me tell you, the way that diamond is cut is absolutely essential when it comes to its shine and radiance. It truly revolves around the flawless precision and shape of every single facet.

What diamond companies don't want you to know

You may think that the most expensive diamond is always the one with the perfect cut, designed to dazzle with maximum sparkle. However, that's not always the case. Surprisingly, a diamond with a "Fair" cut, but with the same carat, color, and clarity, can actually cost more. It may sound odd, but diamonds that are poorly cut can give off the impression of being larger, while lacking the sparkle and brilliance that you crave. A diamond without sparkle is like a book without any words.

Remember this final advice: stick with GIA Certified Excellent Cut Diamonds (commonly called "Ideal" Cut).

Lesson 7 - Shape

Not all diamond shapes are equally sparkly; some shapes can give the illusion of a higher cost in 2.5 carat oval diamond rings.

What is Diamond Shape?

The style of a diamond is determined by its shape, like round, oval, or other shapes. Different shapes can create the illusion of a larger diamond or offer a more sparkling and classic appearance. Take a look at our shape tool in this section to discover a variety of 2.5 carat diamond rings with different shapes.

What shape to choose?

It's important to keep in mind that certain diamond shapes can make a diamond look bigger than it actually is, and some shapes are currently in style. But the most important thing is to choose the shape that feels right for you. If you need some suggestions, a brilliant cut diamond is a good choice. This includes Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant shapes. Out of these options, Round diamonds are the most popular, but Oval and Marquise shapes can make a diamond appear larger even with the same carat weight.

Lesson 8 - Setting

The band of a 2.5 carat oval diamond ring can completely change its appearance.

What is setting?

The shiny part of a diamond ring, which is often called the band, is known as the setting. These are usually made of gold in different colors like white, yellow, or rose. You can also choose to have a platinum band. The setting plays a crucial role in the overall appearance of your 2.5 carat oval diamond ring. It allows you to showcase your own personal style. Here, we have listed the three most commonly preferred settings. No matter which setting you choose, it's recommended to go for 14k gold. Keep reading to find out why this is the case.
The setting or band is really important for making your diamond look bigger and better. 

Choose a 14K gold ring.

It's really important to keep this rule in mind. Avoid going for 18k or 24k gold for your setting. The smarter option is 14k gold. Even though 18k and 24k gold might be purer, they are much softer and can bend easily. If the setting meant to safeguard your valuable diamond bends, there's a much higher chance of your diamond falling out. Many people have faced this problem.

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

Based on survey data, many women aspire to have a large diamond. To maximize the apparent size of a 2.5 carat oval 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: Make Diamond Look Bigger with Lots of Smaller Diamonds

A halo setting is a fantastic option to make your oval diamond ring with a 2.5 carat stone appear larger. This setting incorporates smaller diamonds that encircle the main stone, producing a glowing aura that magnifies the size of the central diamond. If you desire an even greater illusion of size, you might want to consider a double halo setting. When combined with a slender band, this particular setting can create the illusion of a larger diamond, resulting in a truly remarkable piece.

Make sure to focus on the main diamond.

A lot of women like their diamond to appear big. If your ring's band is too extravagant or wide, it can shift attention away from the diamond, making it seem smaller in comparison. If your top priority is the 2.5 carat oval diamond ring, then a simpler band would be the smartest choice. On the other hand, if the overall design of the ring is what matters most to you, then a more intricate band might be perfect. Just keep in mind that this could potentially diminish the diamond's visibility.
