Lesson 2 - Clarity

When shopping for a 0.3 carat princess cut diamond ring, the clarity of the diamond plays a major role in determining its price.

⊗ Up to $384 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

The clarity of a diamond is a term used to describe how visible its imperfections are. However, it's important to remember that "visible" typically means visible when looking at the diamond through a 10x magnifying glass. The clarity scale goes from 'flawless' (FL) to 'included' (I), and there are also grades in between like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included). Diamonds in these categories often have imperfections that can only be seen under 10x magnification. Therefore, to the naked eye, they will generally appear completely clear, making sure your ring looks flawless to everyone who sees it!

Optimal Clarity Range for a 0.3 carat princess cut diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 0.3 carat princess cut diamond ring can result in significant savings, potentially reducing the total price by up to $384. We strongly suggest considering the VS2 clarity grade due to its favorable combination of price and clarity. However, it is important not to disregard SI1 diamonds, as with a brief examination of available options, you can discover ones that exhibit 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

When looking for a princess cut diamond ring that weighs 0.3 carats, the diamond's color has a big impact on its price.

⊗ Up to $164 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 Gemological Institute of America (GIA) ranks diamonds on a scale from D (colorless) to Z (yellow or brown). The majority of diamonds in jewelry fall within the G-H range, meaning they have a slight hint of color. This color is only noticeable when compared to higher-grade diamonds like D, E, or F. While larger diamonds may show more visible color, a princess diamond from the G-H range will still appear nearly colorless and be less expensive than a D-grade diamond, which is completely colorless.

Optimal Color Range For A 0.3 Carat Princess Cut Diamond Ring

Choosing the right color grade for a 0.3 carat princess cut diamond ring can lead to significant savings. Instead of paying premium prices for diamonds graded D-F, consider opting for a diamond in the G-J range. This decision can still result in a breathtaking piece while saving you up to $164, in addition to any savings from smart choices concerning 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 up to $300 on your 0.3 carat princess cut diamond ring with the choice of a lab grown diamond.

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.

If you ever find yourself needing to sell your 0.3 carat princess cut diamond ring, choosing a lab-grown diamond can help mitigate your financial loss.

Choosing the right color grade for a 0.3 carat princess cut diamond ring can lead to significant savings. Instead of paying premium prices for diamonds graded D-F, consider opting for a diamond in the G-J range. This decision can still result in a breathtaking piece while saving you up to $164, in addition to any savings from smart choices concerning clarity.

Lesson 5 - Carat / Size

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

Why is Carat Important?

Imagine a diamond ring for a moment. What stands out the most? It's definitely the size of the main diamond! Women agree on this - surveys show that size is the most important factor. That's why our budget recommendation is straightforward: pay attention to the carat weight, which directly determines the size.
Watch us compare sizes and help you visualize what you want. 

This carat range is the perfect choice for a 0.3 carat princess cut diamond ring.

It would be a good idea to check out diamonds in the 0.27 to 0.33 carat range. This way, you can get an idea of the various price ranges without compromising much on size.

Lesson 6 - Cut

Always consider the cut of the diamond as it determines its sparkle. When buying your 0.3 carat princess cut 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 gorgeous princess cut diamond ring that weighs 0.3 carats, the way it is cut becomes really important. The cut determines how precise and perfect the angles of the diamond are, and this affects how much the ring sparkles and shines overall.

The behind-the-scenes truth about diamonds

The idea that a diamond cut to perfection, designed to shine its brightest, would always be the most expensive option isn't always true. Sometimes, a diamond with a fair cut, but with the same carat, color, and clarity, can end up being pricier. This might sound strange, but it happens because diamonds that are poorly cut might seem bigger but lack that sparkle and brilliance. A diamond without sparkle is like a painting without any colors.

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

Lesson 7 - Shape

The sparkliness of diamonds varies depending on their shape, and some shapes can add to the perceived value of a 0.3 carat princess cut diamond ring.

What is Diamond Shape?

The shape of a diamond determines its style. It can be round, oval, or princess, among others. Different shapes can give the illusion of a bigger diamond, while some highlight its sparkle and classic charm. In this section, you can use our shape tool to browse through a collection of 0.3 carat diamond rings in various shapes.

What shape to choose?

Sure, some diamond shapes can make the stone look bigger, and some shapes are popular right now. But remember, what really counts is what makes you the happiest. If you're not sure, a brilliant cut diamond, such as Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant shapes, might be your best bet. Out of these, Round diamonds are the most popular, while Oval and Marquise shapes can give the impression of a larger diamond without weighing more.

Lesson 8 - Setting

The band of a 0.3 carat princess cut diamond ring can have a significant impact on its overall appearance.

What is setting?

The metallic part of a diamond ring that holds the stone, often called the band, is called the setting. These are typically made of gold in various colors like white, yellow, or rose. Alternatively, you can choose to have a platinum band. The setting plays a vital role in the overall appearance of your 0.3 carat princess cut diamond ring. It allows you to showcase your individual style. Below, we've outlined the three most commonly preferred settings. No matter which one you choose, it is always recommended to select 14k gold. Keep reading to find out why this is advised.
The setting or band is really important for making your diamond look bigger and better. 

Try to get a 14K gold band for your 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 Choice - A Delicate Band Makes the Diamond Stand Out

According to survey results, a lot of women desire a big diamond. If you want to make a 0.3 carat princess cut diamond ring look bigger, go for a Solitaire setting with a thin, elegant band. The difference in size between the band and the diamond can create the illusion of a larger stone. To enhance this effect, find a setting with small accent diamonds on the band. These will add a classy touch without diverting attention from the main diamond.

Halo: Enhance the Appearance of Your Diamond by Encircling It with Smaller Ones

Choosing a halo setting is a clever choice to make your 0.3 carat princess cut diamond ring appear bigger. This kind of setting involves smaller diamonds encircling the main stone, creating a dazzling effect that enhances the diamond's perceived size. If you're looking to go all out, pairing a double halo setting with a slim band can make even a petite diamond seem significantly larger, exuding the luxurious feel of a more extravagant ring.

The main diamond needs to stay the focal point.

Many women prefer to have a diamond that looks big. If the band of the ring is too fancy or wide, it could take away from the diamond and make it seem smaller. If you want your 0.3 carat princess cut diamond ring to be the main focus, it's smart to pick a simple and nondescript band. However, if you care more about the overall look of the ring, you might opt for a fancy band, but be cautious because this could diminish the diamond's importance.
