Lesson 2 - Clarity

When searching for a 0.3 carat round diamond ring, keep in mind that the clarity of the diamond is what determines its price the most.

⊗ Up to $117,474 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 how flawless they appear. However, it's important to note that the term "noticeable" is key here, as most imperfections can only be seen under a 10x magnifying glass. Diamond clarity is categorized from 'flawless' (FL) to 'included' (I), with classifications like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included) falling in between. Diamonds in these categories often have blemishes that can only be seen with a 10x magnifier. So, to the naked eye, they usually look completely clear, ensuring that anyone admiring your ring won't notice any flaws!

Optimal Clarity Range for a 4 carat diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 4 carat diamond ring can result in significant savings, potentially reducing the total price by up to $117,474. When considering the clarity options, we strongly suggest considering the VS2 range due to its favorable combination of price and clarity. However, it is important not to dismiss SI1 diamonds altogether. With just a few minutes of carefully examining different diamonds, you can easily find SI1 diamonds that appear 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 color of the diamond you choose has a big impact on the price of a 4 carat diamond ring.

⊗ Up to $20,061 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can have a yellowish 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 minimal color and fall in the G-H range. Only when compared to higher-ranked diamonds like D, E, or F, can you detect slight traces of color. Although color is more noticeable in larger diamonds, those in the G-H range still appear almost colorless and are less costly than completely colorless diamonds like those with a D-grade.

Optimal Color Range For A 4 Carat Diamond Ring

Choosing the appropriate color grade for a 4 carat diamond ring can lead to significant cost reductions. Rather than paying premium prices for diamonds graded D-F, it is recommended to opt for diamonds within the G-J range. This selection can still result in an exquisite piece of jewelry while saving you up to $20,061, in addition to potential savings from wise decisions concerning clarity.

Lesson 5 - Carat / Size

Invest more in carat size for a bigger gem in your diamond ring.

Why is Carat Important?

The first thing everyone thinks about when it comes to a diamond ring is the size of the main diamond in the center. In fact, when women are asked, the most important aspect of the ring to them is the size of the center diamond. The carat weight directly affects how big the diamond appears, so we suggest allocating most of your budget towards this.
Watch us compare sizes and help you visualize what you want. 

When you're shopping for a 4-carat diamond ring, make sure to consider this carat range.

You should check out diamonds that range from 3.6 to 4.4 carats. Doing so will give you a good sense of the price differences without a significant change in size.

Lesson 6 - Cut

When purchasing your 4 carat diamond ring, keep in mind that the cut of the diamond determines its sparkle and shine. Opt for an ideal or excellent cut to enhance its beauty.

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

What is Cut?

The secret to a stunning 4 carat diamond ring lies in the diamond's cut. It's all about the flawless shaping and meticulous arrangement of the diamond's facets, which directly impact its overall shine and beauty.

A hidden truth within the diamond industry

You might think that the most expensive diamond is always the one with the perfect cut, known as the 'Ideal' cut. But surprisingly, there are cases where a diamond with a 'Fair' cut can be pricier, even if it has the same carat, color, and clarity. It may sound strange, but diamonds that are poorly cut can appear larger while lacking the sparkle and brilliance you're looking for. A diamond without sparkle is like a kite without a string.

Here's a valuable 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 4 carat diamond rings look more expensive.

What is Diamond Shape?

Diamonds come in various shapes, like round, oval, and many more. Each shape has its own style. Some shapes can make a diamond look bigger, while others enhance its sparkle and timeless beauty. In this section, you can use our shape tool to explore a wide range of 4 carat diamond rings, each featuring a different shape.

What shape to choose?

Some of these shapes will definitely give the diamond a bigger appearance, while others are more fashionable. Nevertheless, when it comes down to it, the choice should be all about what appeals to you and brings you the most joy. If you can't decide, you can always opt for a brilliant cut diamond, which includes shapes like Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant. Round is the most widely seen shape, while Oval and Marquise will make the diamond appear larger, even with the same carat weight.

Lesson 8 - Setting

The appearance of a 4 carat diamond ring can vary greatly depending on the band it is set in, depending on which band you choose, the look of the ring can change significantly.

What is setting?

Often referred to as the band, the setting is the golden part of the diamond ring. Typically, it is made of gold in different shades like white, yellow, or rose gold. Another option to consider is a platinum band. The setting greatly affects the overall appearance of your 4 carat diamond ring. This is where you have the opportunity to showcase your personal style preferences. Below, we have highlighted the three most favored settings. Regardless of which one you choose, we suggest sticking with 14k gold. The reasons supporting this recommendation will be elaborated on later.
The setting or band is really important for making your diamond look bigger and better. 

Choose 14 karat gold as the material for your band.

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 - A Great Band for a Flashier Diamond Presentation

Poll results indicate that most women have a preference for large diamonds. A way to highlight the size of a 4 carat diamond ring is by choosing a Solitaire setting with a fine, delicate band. The difference in size between the tiny band and the large diamond can generate an illusion of an even bigger stone. Adding small accent diamonds along the band can also amplify this effect, providing decorative detail without overshadowing the central diamond.

Halo: Make Your Diamond Look Bigger with a Bunch of Smaller Stones

Choosing a halo setting is a clever choice to make your 4 carat diamond ring appear bigger. This setting features smaller diamonds surrounding the main stone, creating a dazzling effect that enhances the perceived size of the diamond. If you're aiming for something bolder, combining a double halo setting with a slender band can make even a small diamond appear significantly larger, exuding the luxurious vibe of a more extravagant ring.

Make sure to focus on the main diamond.

Many women want a diamond that appears large. An overly ornate or wide band can take away from the diamond and make it look smaller in comparison. If you want your 4 carat diamond ring to really stand out, it could be wise to opt for a simpler band. However, if you value the overall design of the entire ring, a detailed band might be your preference, but keep in mind that this could lessen the impact of the diamond's brilliance.
