Lesson 2 - Clarity

When shopping for a 0.2 carat round diamond ring, the diamond's clarity is the primary pricing factor to keep in mind.

⊗ Up to $130,631 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 diamond ring

Choosing a diamond within the VS2-SI1 clarity range for your 3 carat diamond ring can result in significant savings, potentially reducing the total price by as much as $130,631. We strongly suggest considering diamonds with a VS2 clarity grade due to their favorable combination of price and clarity. However, it is important not to disregard SI1 diamonds either. By spending just a few minutes examining different diamonds, you can discover SI1 stones that have an appearance that is virtually 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 looking for a 3 carat diamond ring, the diamond's color has a big impact on its price.

⊗ Up to $12,598 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can come in various shades, ranging from yellowish to completely colorless. The Gemological Institute of America (GIA) ranks diamonds on a scale from D (colorless) to Z (yellow or brown). Most jewelry diamonds have a slight amount of color and fall into the G-H category. These subtle color differences can only be detected when comparing them to higher-graded diamonds like D, E, or F. While larger diamonds may show more noticeable color, a diamond from the G-H category will still appear nearly colorless and will be less expensive than a D-grade diamond, which is completely colorless.

Optimal Color Range For A 3 Carat Diamond Ring

Opting for the appropriate color grade for a 3 carat diamond ring can lead to significant cost reductions. Instead of paying exorbitant prices for diamonds graded D-F, consider selecting a diamond falling within the G-J range. By doing so, you can still obtain a breathtaking piece and save as much as $12,598, in addition to any savings resulting from wise decisions pertaining to clarity.

Lab Grown Diamonds

Lab grown diamonds can often cut prices in half and no one will ever notice the difference. 

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

Save over $32,000 on your 3 carat diamond ring by opting for a lab grown diamond.

Lab-grown diamonds, which are created in a lab rather than mined from the earth, have the same visual qualities as diamonds found in nature. They are produced in a more environmentally friendly and ethical manner. Additionally, lab-grown diamonds are more readily available and therefore much more affordable. In fact, the cost of a lab-grown diamond can be up to 85% lower than that of a comparable natural diamond.

If you ever have to sell your 3 carat diamond ring, choosing a lab-grown diamond can help minimize your financial loss.

Opting for the appropriate color grade for a 3 carat diamond ring can lead to significant cost reductions. Instead of paying exorbitant prices for diamonds graded D-F, consider selecting a diamond falling within the G-J range. By doing so, you can still obtain a breathtaking piece and save as much as $12,598, in addition to any savings resulting from wise decisions pertaining to clarity.

Lesson 5 - Carat / Size

When you are looking for your diamond ring, focus your money on the carat size.

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. 

Keep an eye out for this carat range when looking for a 3 carat diamond ring.

We suggest checking out diamonds that are between 2.7 and 3.3 carats. This way, you can explore different prices without a significant change in size.

Lesson 6 - Cut

Don't underestimate the importance of the cut when it comes to a diamond's sparkle. Ensure you choose an ideal or excellent cut for your 3 carat diamond ring.

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

What is Cut?

Are you in search of the most stunning 3 carat diamond ring? Keep in mind that it's the cut that truly matters - the flawless and precise angles of the diamond - that ultimately determine its dazzling sparkle and brilliance.

What diamond companies don't want you to know

An 'Ideal' cut diamond is known for its maximum sparkle and is often thought to be the most expensive. But sometimes, a 'Fair' cut diamond with the same carat, color, and clarity can be even pricier. It may seem confusing, but poorly cut diamonds can appear larger without giving off the desired sparkle and brilliance. A diamond that lacks sparkle is like a garden without any soil.

One last thing to keep in mind: go for GIA Certified Excellent Cut Diamonds (also known as "Ideal" Cut).

Lesson 7 - Shape

The brilliance of diamonds is influenced by their shape, and specific shapes can contribute to the perceived value of a 3 carat diamond ring.

What is Diamond Shape?

The shape of a diamond determines its style, such as being round, oval, or different variations. There are many different shapes available, each with its own unique qualities. Some shapes can make a diamond appear larger than it is, while others add extra sparkle and timeless charm. You can explore a wide range of 3 carat diamond rings with various shapes using our shape tool in this section.

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 has the ability to completely alter the appearance of a 3 carat diamond ring.

What is setting?

Commonly known as the band, the setting is the metal part of the diamond ring. It's typically made of gold and comes in white, yellow, or rose gold options. Another choice could be a platinum band. The setting plays a crucial role in the overall look of your 3 carat diamond ring. This is where you can express your personal style. Below, we've listed the three most popular settings. No matter which setting you choose, it's recommended to go with 14k gold. Keep reading to find out why this is a good idea.
The setting or band is really important for making your diamond look bigger and better. 

It's always best to go with 14K Gold when selecting your ring band.

Here's an important rule to remember. Avoid using 18k or 24k gold for your jewelry setting. Instead, go for 14k gold. Even though 18k and 24k gold are purer, they are much softer and more prone to bending. If the band holding your precious diamond bends easily, there is a much higher risk of the diamond falling off. This is a problem that many people commonly experience.

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 3 carat 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 design provides an alternative method to make your 3 carat diamond ring appear bigger. By surrounding the main diamond with smaller ones, it creates a dazzling effect that enhances the size of the central diamond. To truly enhance the illusion, you could consider choosing a double halo design. Pairing it with a slim band can make a smaller diamond appear much larger, giving off a luxurious vibe.

The main diamond should be the focal point.

Many women prefer a diamond that looks big. A band that is too detailed or wide might take attention away from the diamond, making it seem smaller. If you want your 3 carat diamond ring to be the main attraction, you might want to choose a simpler band that won't overshadow it. However, if the overall design of the ring is more important to you, a more decorative band might be to your liking. Just remember, it could diminish the standout quality of the diamond.
