Lesson 2 - Clarity

When shopping for a 0.25 carat pear shaped diamond ring, the diamond's clarity is the primary pricing factor to keep in mind.

⊗ Up to $129,744 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

Clarity is all about the flaws you can see in a diamond, but it's worth mentioning that most flaws are only visible with a 10x magnifying glass. Diamond clarity can be categorized as 'flawless' or 'included'. In between, you'll come across classifications like VS1, VS2, and SI1. These diamonds might have imperfections that can only be seen under 10x magnification. To the naked eye, they are typically invisible, so no one will notice them when they admire your ring!

Optimal Clarity Range for a 3 carat round diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 3 carat round diamond ring can result in significant savings, potentially reducing the total price by as much as $129,744. When it comes to the balance between price and clarity, we highly recommend opting for a diamond in the VS2 range. However, it is essential not to dismiss SI1 diamonds. By dedicating a few minutes to carefully examining the available options, you can discover SI1 diamonds that have an appearance that is nearly 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

The cost of a 3 carat round diamond ring is heavily impacted by the chosen diamond's color.

⊗ Up to $12,928 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can either have a yellowish tint or no color at all. The Gemological Institute of America (GIA) rates diamonds on a scale from D (colorless) to Z (yellow or brown). The majority of diamonds used in jewelry have a slight amount of color and fall within the G-H range. The subtle hints of color in these diamonds are typically only noticeable when compared to higher-grade diamonds like D, E, or F. Although larger diamonds may show color more prominently, a round diamond from the G-H range will still appear nearly colorless and will be less expensive than completely colorless diamonds, such as those in the D-grade.

Optimal Color Range For A 3 Carat Round Diamond Ring

Opting for a 3 carat round diamond ring in the appropriate color grade can lead to significant cost reductions. Instead of splurging on top-tier D-F graded diamonds, consider selecting one in the G-J range. By doing so, you can still acquire an exquisite piece while saving up to $12,928, in addition to any savings derived from making astute choices regarding clarity.

Lesson 5 - Carat / Size

Focus on the carat weight when you're shopping for a diamond ring.

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. 

This Carat Range: The Perfect Choice for Your 3-carat round diamond ring.

We recommend looking at diamonds that range from 2.7 to 3.3 carats. This will give you a variety of prices without a significant increase in size.

Lesson 6 - Cut

The way a diamond is cut directly affects its sparkle. For your 3 carat round 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 gorgeous 3 carat round diamond ring? The way the diamond is cut plays a vital role in how it shines and dazzles. It's all about how every single facet is shaped with utmost precision and accuracy.

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

Consider a diamond's shape since it can impact the sparkle of a 3 carat round diamond ring, making it seem more expensive.

What is Diamond Shape?

When we talk about the shape of a diamond, we mean its style, such as round, oval, or others. There are numerous shapes that can affect the appearance of the diamond. Some shapes can make the diamond look bigger, while others can enhance its sparkle and give it a timeless charm. In this section, you can explore a variety of 3 carat diamond rings with different shapes by using our shape tool.

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 appearance of a 3 carat round diamond ring can vary greatly depending on the band it is set in.

What is setting?

The part of a diamond ring that holds the stone, called the band, is usually made of gold. It comes in different colors like white, yellow, or rose gold. There's also the option of a platinum band. The way the diamond is set plays a big role in how the ring looks. It's a chance to show off your personal style. There are three main types of settings that are commonly used. No matter which one you choose, it's best to go with 14k gold. The reason for this will become clear as you keep reading.
The setting or band is really important for making your diamond look bigger and better. 

Choose a 14K gold ring.

Here's a crucial rule to follow. Avoid choosing 18k or 24k gold for your setting. It's better to opt for 14k gold. Despite 18k and 24k gold being more pure, they are considerably softer and prone to bending. If the setting that secures your valuable diamond bends excessively, the chance of the diamond becoming loose and falling out rises significantly. Numerous individuals have faced this issue.

Solitaire Setting - A Slim Band Accentuates the Look of a Larger Diamond

Survey data indicates that a large diamond is a common desire among women. To visually enhance the size of a 3 carat round 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: Boost Your Diamond's Volume with Many Small Gems

The halo setting provides an additional method to enhance the apparent size of your 3 carat round diamond ring. By surrounding the main diamond with smaller ones, it produces a glowing effect that makes the primary diamond seem bigger. To further enhance this illusion, you can choose a double halo setting. Combined with a slim band, this can make a smaller diamond appear considerably larger, giving the impression of a more luxurious piece.

Maintain the Main Diamond's Dominance

A lot of ladies prefer a diamond that appears large. If the band of your ring is too fancy or wide, it could take away attention from the diamond, making it look smaller. If your goal is to highlight your 3 carat round 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 detailed band might be what you want, just keep in mind that this could make the diamond lose some of its shine.
