Lesson 2 - Clarity

If you're in the market for a 1 carat radiant cut diamond ring, remember that the diamond's clarity is the biggest factor in determining its price.

⊗ Up to $5,220 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 1 carat radiant cut diamond ring

Choosing a 1 carat radiant cut diamond ring can lead to significant savings when opting for a diamond in the VS2-SI1 clarity range. In fact, you could potentially save as much as $5,220 off the total price. We highly advise considering the VS2 clarity grade due to its favorable balance of price and clarity. However, it is important not to disregard SI1 diamonds. With just a few minutes of sifting through diamonds, you can easily find SI1 diamonds 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

The color of a diamond is a major factor in determining the price of a 1 carat radiant cut diamond ring.

⊗ Up to $935 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 faint traces of color. Although color is more noticeable in larger diamonds, a radiant diamond in the G-H range will still appear almost colorless and won't be as costly as completely colorless diamonds, such as those with a D-grade.

Optimal Color Range For A 1 Carat Radiant Cut Diamond Ring

Opting for a 1 carat radiant cut diamond ring offers a marvelous choice for those seeking elegance and brilliance. Selecting a diamond in the I-J color range allows for remarkable savings compared to the more expensive D-F graded diamonds. By making this wise decision, you can potentially save up to $935, in addition to any savings achieved through clarity considerations.

Lesson 5 - Carat / Size

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

Why is Carat Important?

Picture a diamond ring. The size of the central diamond really catches your attention, doesn't it? Well, surveys indicate that women concur - it's the most crucial aspect. The higher the carat, the larger the diamond, and that's where we suggest you invest your funds.
Watch us compare sizes and help you visualize what you want. 

When you're shopping for a 1 carat radiant cut diamond ring, consider selecting from this carat range.

You might want to check out diamonds in the 0.9 to 1.1 carat range. That way, you can see some nice differences in prices without a big change in size.

Lesson 6 - Cut

The way a diamond is cut directly affects its sparkle. For your 1 carat radiant cut 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?

If you're looking for a stunning 1 carat radiant cut diamond ring, the way it's cut plays a crucial role. The cut determines how precise and flawless the diamond's angles are, and this has a direct impact on the ring's sparkle and brilliance.

The behind-the-scenes truth about diamonds

You'd probably assume that an 'Ideal' cut diamond, which is famous for its flawless sparkle, would always be the most expensive choice. However, there are cases where a 'Fair' cut diamond, despite having the same carat, color, and clarity, can be more costly. It might not make sense at first, but diamonds that are poorly cut can actually appear larger while lacking the desired sparkle and brilliance. A diamond without any sparkle is comparable to a smartphone without a battery.

Keep this in mind: go for GIA Certified Excellent Cut Diamonds (sometimes referred to as "Ideal" Cut).

Lesson 7 - Shape

The level of sparkle in diamonds depends on their shape, and some shapes can create the impression of a pricier 1 carat radiant cut diamond ring.

What is Diamond Shape?

When we talk about the diamond shape, we're referring to the way the diamond is cut, like round, oval, or radiant. Different shapes can create the illusion of a larger diamond, while others give off more sparkle and a classic appeal. Take a look at our shape tool in this section to browse through a variety of 1 carat diamond rings available in various shapes.

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 overall look of a 1 carat radiant cut diamond ring can be greatly affected by the type of band it has.

What is setting?

The part of the diamond ring that's made of metal, usually called the band, is called the setting. It's usually made of gold and comes in different colors like white, yellow, or rose. You can also choose a band made of platinum. The setting is really important for how your 1 carat radiant cut diamond ring looks overall. This is where you can show off your personal style. Below, we've listed the three most popular settings. No matter which setting you pick, we recommend going with 14k gold. Keep reading to find out why we think this is the best choice.
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 Setting - A Slim Band Accentuates the Look of a Larger Diamond

Many women, when surveyed, prefer a large diamond. To emphasize the size of a 1 carat radiant cut diamond ring, a thin, delicate band in a Solitaire setting can be considered. The stark contrast between the smaller band and the larger diamond can create an illusion of a larger stone. Accent diamonds along the band can further boost this illusion, providing decorative detail without detracting from the main diamond.

Halo: Boost Your Diamond's Volume with Many Small Gems

Choosing a halo design is a clever choice to enhance the appearance of your 1 carat radiant cut diamond ring. This setting involves smaller diamonds surrounding the main stone, creating a dazzling effect that makes the diamond appear bigger. If you're looking to go beyond the norm, a double halo setting combined with a slim band can make even a small diamond seem significantly larger, giving the impression of a more extravagant ring.

The main diamond should be the focal point.

Most women prefer a big diamond. If your ring has too many decorations or is too wide, it might make the diamond appear smaller. If you really want a 1 carat radiant cut diamond ring, a simpler band would be a good choice. However, if you care more about the overall design of the ring, a fancier band might be better, but remember that it could take attention away from the diamond.
