Lesson 2 - Clarity

If you're looking to buy a 0.3 carat oval diamond ring, the clarity of the diamond is the primary factor that affects its cost.

⊗ Up to $634 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

Clarity in diamonds refers to how easily you can see the imperfections. The important thing to note is that most of these flaws can only be seen under a 10x magnifying glass. The diamond clarity scale ranges from 'flawless' (FL) to 'included' (I), with grades like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included) in between. Diamonds with these clarity grades usually have imperfections that are only visible under 10x magnification, so they will appear perfectly clear to the naked eye. This ensures that anyone admiring your ring won't notice any flaws!

Optimal Clarity Range for a 0.3 carat oval diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 0.3 carat oval diamond ring can result in significant savings, potentially reducing the total price by as much as $634. In terms of price and clarity, we strongly suggest considering diamonds in the VS2 range. However, it is important not to disregard SI1 diamonds. By taking a few minutes to carefully examine different diamonds, you can easily find ones that have 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 you choose for a 0.3 carat oval diamond ring greatly affects its price.

⊗ Up to $190 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 0.3 Carat Oval Diamond Ring

Opting for the appropriate color grade when selecting a 0.3 carat oval diamond ring can lead to considerable savings. Instead of paying exorbitant prices for diamonds graded D-F, it is wise to consider a diamond falling within the G-J range. This decision can still guarantee a breathtaking piece while potentially saving you up to $190, in addition to any savings achieved through making astute clarity-related choices. When it comes to more intricate designs such as a halo diamond ring, comprised of numerous smaller diamonds encircling the central stone, it is recommended to choose a central diamond graded within the G-H color range. This approach ensures that no discernible color contrast arises when compared to the smaller diamonds within the halo, which are usually colorless or nearly colorless, and helps maintain the overall aesthetic appeal of the ring.

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.

Discover how lab grown diamonds can help you save up to $500 on your 0.3 carat oval diamond ring.

Lab-grown diamonds, also called lab-created diamonds, possess an indistinguishable look from genuine diamonds but are manufactured in a more environmentally friendly and morally conscious process. Additionally, they offer a greater affordability owing to their increased accessibility compared to natural diamonds. In fact, a lab-grown diamond can be up to 85% cheaper than a similar natural diamond.

Choosing a Lab-Grown Diamond for Your 0.3 Carat Oval Ring Can Reduce Your Financial Loss.

Opting for the appropriate color grade when selecting a 0.3 carat oval diamond ring can lead to considerable savings. Instead of paying exorbitant prices for diamonds graded D-F, it is wise to consider a diamond falling within the G-J range. This decision can still guarantee a breathtaking piece while potentially saving you up to $190, in addition to any savings achieved through making astute clarity-related choices.

Lesson 5 - Carat / Size

Focus on the carat weight as your primary consideration when shopping for a diamond ring.

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. 

The best carat range for shopping for a 0.3 carat oval diamond ring.

We recommend looking at diamonds that range from 0.27 to 0.33 carats. This way, you'll get a variety of prices without a significant increase in size.

Lesson 6 - Cut

The cut of a diamond is what gives it that beautiful sparkle. For your 0.3 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?

When it comes to a stunning 0.3 carat oval diamond ring, the cut is absolutely crucial. The way the diamond's facets are shaped and placed can really elevate its shine and shine.

What diamond companies don't want you to know

In the world of diamond cuts, you'd think that an 'Ideal' cut diamond – crafted to shine brilliantly with flawless proportions – would always be the priciest one. But truth be told, there are instances where a 'Fair' cut diamond, with the same carat, color, and clarity, can actually be more expensive. It may sound strange, but diamonds that are poorly cut can appear larger yet lack the desired sparkle and brilliance. A diamond without sparkle is similar to a movie without sound.

Remember this final advice: stick with GIA Certified Excellent Cut Diamonds (commonly called "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 0.3 carat oval diamond ring.

What is Diamond Shape?

The diamond's style is all about its shape, such as round, oval, and many more. Different shapes can make a diamond look bigger or add more sparkle and timeless beauty. Check out our shape tool in this section to explore a wide range of 0.3 carat diamond rings with 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 has the potential to completely transform the look of a 0.3 carat oval diamond ring.

What is setting?

The part of a diamond ring that holds the stone, also known as the band, is usually made of gold in different colors like white, yellow, or rose. Another option is a band made of platinum. The band is important in determining the overall appearance of your 0.3 carat oval diamond ring. It allows you to showcase your personal style. Below, we have described the three most popular band options. Regardless of your preference, it is recommended to choose 14k gold. Continue reading to find out why.
The setting or band is really important for making your diamond look bigger and better. 

You should choose a 14K Gold band.

Remember this important guideline. Don't use 18 karat or 24 karat gold for your setting. Go with 14 karat gold instead. Even though 18 karat and 24 karat gold are more pure, they are noticeably less durable and prone to bending. If your precious diamond's setting bends too easily, there's a significant risk of the diamond becoming loose and falling out. This is a common problem for many people.

Solitaire - A Great Band for a Flashier Diamond Presentation

According to surveys, most women want a big diamond. A thin and delicate Solitaire band can make a 0.3 carat oval diamond ring look even bigger. The contrast of the small band and the large diamond tricks the eye into thinking the stone is even larger. Adding small accent diamonds on the band enhances this effect, giving it a classy touch without taking away from the main diamond.

Halo: Make Your Diamond Look Bigger with a Collection of Small Stones

Choosing a halo setting is a clever choice to enhance the appearance of your 0.3 carat oval diamond ring. This setting involves smaller diamonds surrounding the main stone, creating a dazzling effect that makes the diamond seem larger. If you're seeking to go beyond the norm, a double halo setting combined with a slim band can make even a small diamond appear significantly bigger, giving the impression of a more extravagant ring.

Keep the focus on the main diamond.

A lot of ladies are attracted to a diamond that looks large. If the band is too fancy or wide, it might take away the focus from the diamond and make it seem smaller. If you want to showcase your 0.3 carat oval diamond ring, go for a simple band that won't overshadow it. On the other hand, if the overall design of the ring is what captivates you, a band with intricate details might suit your taste. Just keep in mind that this could diminish the diamond's prominence.
