Lesson 2 - Clarity

When shopping for a 1.5 carat radiant cut diamond ring, the diamond's clarity is the key factor that affects its pricing.

⊗ Up to $16,565 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 noticeable any imperfections are. The main focus is on how easily these flaws can be seen, as most of them can only be detected with a 10x magnifying tool. A diamond's clarity can range from 'flawless' (FL) to 'included' (I), with various classifications like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included) falling in between. These types of diamonds typically have imperfections that can only be seen under 10x magnification. So, to the naked eye, they will appear completely clear – meaning anyone admiring your ring won't have a clue about any flaws!

Optimal Clarity Range for a 1.5 carat radiant cut diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 1.5 carat radiant cut diamond ring can result in significant savings, potentially reducing the total price by as much as $16,565. We suggest considering the VS2 clarity grade, as it offers a good balance between price and clarity. However, it is also worth mentioning that SI1 diamonds should not be disregarded. By taking a few minutes to carefully examine the diamonds, you can find ones 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.

However, it's important to understand that not all SI1 diamonds are the same. While some might not meet your expectations, many of them are truly stunning and have a similar look to a VS2 diamond.

Lesson 3 - Color

The cost of a 1.5 carat radiant cut diamond ring is greatly influenced by the diamond's color.

⊗ Up to $2,735 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can come in different shades, ranging from slightly yellowish to completely clear. The Gemological Institute of America (GIA) rates them on a scale from D (no color) to Z (yellow or brown). When it comes to jewelry, diamonds usually have a slight hint of color and fall within the G-H range. The subtle traces of color in these diamonds can only be detected when compared to higher-grade ones like D, E, or F. While smaller diamonds may not show as much color, larger ones in the G-H range, like a radiant cut, will still appear almost colorless. Additionally, they will be less expensive than a D-grade diamond, which is completely colorless.

Optimal Color Range For A 1.5 Carat Radiant Cut Diamond Ring

Selecting a radiant cut diamond ring with a 1.5 carat stone can lead to significant savings. Instead of paying premium prices for diamonds in the D-F color grade, consider choosing a diamond in the G-J range. This decision can still result in an exquisite piece while saving you up to $2,735, in addition to any savings from wise clarity choices.

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 $7,200 on your 1.5 carat radiant cut diamond ring by opting for lab grown diamonds.

Lab-grown diamonds are diamonds that are created in a laboratory setting. These diamonds possess identical visual characteristics to those found in nature but are manufactured in a manner that is more environmentally friendly and morally sound. Additionally, lab-grown diamonds are more budget-friendly because they are more readily accessible than natural diamonds. In fact, a lab-grown diamond can be up to 85% cheaper than a similar diamond found in nature.

If you ever find yourself in a situation where you have to sell your 1.5 carat radiant cut diamond ring, choosing a lab-grown diamond can help you minimize your financial loss.

Selecting a radiant cut diamond ring with a 1.5 carat stone can lead to significant savings. Instead of paying premium prices for diamonds in the D-F color grade, consider choosing a diamond in the G-J range. This decision can still result in an exquisite piece while saving you up to $2,735, in addition to any savings from wise clarity choices.

Lesson 5 - Carat / Size

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

Why is Carat Important?

Imagine a diamond ring. What's the main attraction? The size of the center diamond, of course. It's no secret - women agree that size is important according to surveys. And since the carat weight determines the size of the diamond, that's where we suggest you spend your money.
Watch us compare sizes and help you visualize what you want. 

If you're looking to buy a 1.5 carat radiant cut diamond ring, consider selecting from this carat range.

You may want to consider looking at diamonds that range from 1.35 to 1.65 carats. This will give you a good selection of prices without a big jump 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 1.5 carat radiant cut diamond ring.

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

What is Cut?

When you're on the hunt for the most beautiful 1.5 carat radiant cut diamond ring, remember that the way it's cut plays a big role in how it shines and sparkles. The cut refers to how precisely and perfectly the angles of the diamond are formed.

The undisclosed secret of diamond companies

You might think that an 'Ideal' cut diamond, which is famous for its perfectly sparkly appearance, is always the most expensive. Well, it turns out that this assumption isn't always accurate. Surprisingly enough, a 'Fair' cut diamond with the same carat, color, and clarity can sometimes be even pricier. It might sound strange, but poorly cut diamonds can actually appear larger while lacking that desired sparkle and brilliance. A diamond without any sparkle is just like a guitar without any strings.

Remember this final advice: stick with GIA Certified Excellent Cut Diamonds (commonly called "Ideal" Cut).

Lesson 7 - Shape

Not all diamond shapes are equally sparkly; some shapes can give the illusion of a higher cost in 1.5 carat radiant cut diamond rings.

What is Diamond Shape?

The diamond shape is like the design of the diamond itself. There are various shapes to choose from, like round, oval, radiant, and many others. Each shape has its own unique characteristics, some can make a diamond look larger, some can make it sparkle more, and some are considered timeless. If you're curious to see how different 1.5 carat diamond rings look with different shapes, you can use our shape tool in this section.

What shape to choose?

When thinking about diamond shapes, it's important to know that some can give the illusion of a bigger stone, and there are shapes that are currently in demand. However, at the end of the day, your choice should be based on what you truly love. If you don't have a strong preference, you might want to consider a brilliant cut diamond, which includes shapes like Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant. Out of these options, Round diamonds are the most popularly chosen, but you might find that Oval and Marquise shapes can make the diamond appear larger even with the same weight in carats.

Lesson 8 - Setting

The band has the power to completely change the appearance of a 1.5 carat radiant cut diamond ring.

What is setting?

The shiny part of a diamond ring, also known as the band, is called the setting. Typically, it's made from gold and comes in white, yellow, or rose gold tones. If you prefer, you can also choose a platinum band. The setting plays a significant role in determining the overall appearance of your 1.5 carat radiant cut diamond ring. It allows you to express your personal style. Below, we've listed the three trendiest settings. No matter which one you choose, it's recommended to opt for 14k gold. As you continue reading, you'll discover the reasons behind this advice.
The setting or band is really important for making your diamond look bigger and better. 

If you're looking for the best option, go with a 14K gold band.

This is a really important rule to keep in mind. Avoid using 18k or 24k gold for your jewelry setting. Instead, go for 14k gold. It's important to mention that even though 18k and 24k gold are purer, they're much easier to bend and reshape. If the setting holding your precious diamond is too flexible, there's a much higher chance of the diamond falling out. It's a common problem that many people have experienced.

Solitaire Setting - A Slim Band Accentuates the Look of a Larger Diamond

As per surveys, the majority of women desire a significantly large diamond. A setting with a thin, delicate Solitaire band could accentuate the size of a 1.5 carat radiant cut diamond ring. The juxtaposition of the small band with the large diamond creates an illusion of a more expansive stone. Small accent diamonds embedded in the band can further this illusion, adding a touch of elegance without detracting from the primary diamond.

Halo: Enhance Your Diamond's Size with Small Diamonds

If you want to make your 1.5 carat radiant cut diamond ring appear bigger, a halo setting could be the ideal choice. In this arrangement, smaller diamonds encircle the main gem, enhancing its brilliance and making it seem larger. You can amplify this effect even more with a double halo setting. When combined with a slim band, this can create the illusion of a much larger diamond, giving off a sense of lavish luxury.

Don't diminish the significance of the main diamond.

Many women desire a diamond that looks impressive. A band that is overly ornate or wide could take attention away from the diamond, making it appear smaller. If you want to highlight your 1.5 carat radiant cut diamond ring, it would be wise to choose a simpler band that doesn't overshadow the stone. However, if you value the overall design of the ring more, a detailed band might be the right choice, but keep in mind that it could diminish the diamond's standout quality.
