Lesson 2 - Clarity

The cost of a 0.33 carat round diamond ring is greatly impacted by the clarity of the diamond.

⊗ Up to $117,367 savings with these tips
Watch us save thousands of dollars by simply selecting the right clarity range.

What is Clarity?

When we talk about diamond clarity, we're basically checking if the diamond has any noticeable imperfections. But here's the catch - these flaws are usually only visible when you use a 10x magnifying glass. Diamond clarity is categorized from 'flawless' (FL) to 'included' (I), with other categories like VS1 (Very Slightly Included), VS2, and SI1 (Slightly Included) falling in between. The flaws in diamonds with these clarity ratings can usually only be seen under 10x magnification. To the naked eye, they will appear crystal clear, so anyone admiring your ring is unlikely to notice anything!

Optimal Clarity Range for a 4.5 carat diamond ring

Choosing a diamond in the VS2-SI1 clarity range for your 4.5 carat diamond ring can result in significant savings, potentially reducing the total price by as much as $117,367. We highly recommend considering diamonds in the VS2 clarity range due to their favorable combination of price and clarity. However, it is important not to disregard SI1 diamonds as well. By investing a few minutes in sifting through diamonds, you can easily find SI1 diamonds that have an appearance that is practically 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 you choose for a 4.5 carat diamond ring greatly affects its price.

⊗ Up to $26,088 savings with these tips
Watch us save thousands by purchasing diamonds in the right range

What is Color?

Diamonds can come in various shades, ranging from yellowish to completely colorless. The Gemological Institute of America (GIA) ranks diamonds on a scale from D (colorless) to Z (yellow or brown). Most jewelry diamonds have a slight amount of color and fall into the G-H category. These subtle color differences can only be detected when comparing them to higher-graded diamonds like D, E, or F. While larger diamonds may show more noticeable color, a diamond from the G-H category will still appear nearly colorless and will be less expensive than a D-grade diamond, which is completely colorless.

Optimal Color Range For A 4.5 Carat Diamond Ring

Choosing the optimal color grade for a 4.5 carat diamond ring can lead to significant cost reductions. Instead of investing in the higher-priced D-F graded diamonds, it is wise to consider a diamond within the G-J range. This decision allows for the acquisition of an exquisite piece while potentially saving up to $26,088, in addition to any savings made by making informed choices regarding clarity. Furthermore, for more intricate designs such as a halo diamond ring, with multiple smaller diamonds encircling the central stone, it is advisable to select a central diamond falling within the G-H color range. This approach ensures the avoidance of any noticeable color contrast that may arise when comparing I-J graded diamonds to the smaller, generally colorless or near-colorless diamonds within the halo.

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 over $73,000 on your 4.5 carat diamond ring by opting for lab grown diamonds.

Lab-grown diamonds are incredibly attractive because they look just like natural diamonds, even though they are made in a lab. What makes them even more appealing is that the way they are produced is environmentally friendly and morally responsible. On top of that, lab-grown diamonds are significantly more affordable than natural diamonds, with prices that can be up to 85% lower.

If you ever find yourself needing to sell your 4.5 carat diamond ring, choosing a lab-grown diamond can help minimize your financial loss.

Choosing the optimal color grade for a 4.5 carat diamond ring can lead to significant cost reductions. Instead of investing in the higher-priced D-F graded diamonds, it is wise to consider a diamond within the G-J range. This decision allows for the acquisition of an exquisite piece while potentially saving up to $26,088, in addition to any savings made by making informed choices regarding clarity.

Lesson 5 - Carat / Size

When you're shopping for your diamond ring, the carat should be your main budget consideration.

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. 

Choosing the Carat Size for Your 4.5 Carat Diamond Ring Shopping

You might want to check out diamonds in the 4.05 to 4.95 carat range. That way, you'll be able to see nice differences in prices without a big difference in size.

Lesson 6 - Cut

When purchasing your 4.5 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?

When you're looking for a remarkable diamond, you have to consider the cut. The cut is extremely important in determining the quality of the diamond's sparkle and brilliance because it involves the precise shaping of all the facets.

The diamond companies well-kept secret

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.

Last but not least, make sure to go for GIA Certified Excellent Cut Diamonds (sometimes referred to as "Ideal" Cut).

Lesson 7 - Shape

Consider a diamond's shape since it can impact the sparkle of a 4.5 carat diamond ring, making it seem more expensive.

What is Diamond Shape?

When we mention the diamond shape, we're talking about the way the diamond is cut, like round, oval, and various others. Different shapes can create the illusion of a larger diamond, while others provide a dazzling sparkle and a classic appeal. Take a look at our shape tool in this section to explore a range of 4.5 carat diamond rings available in various shapes.

What shape to choose?

It's a fact that certain diamond shapes can create the illusion of a larger stone, and currently, some shapes are seen as more fashionable. But when you're deciding, keep in mind that what really counts is what catches your eye and brings you the most joy. If you're unsure and don't have a specific preference, you might want to think about a brilliant cut diamond. This includes shapes like Round, Marquise, Princess, Cushion, Oval, Pear, and Radiant. While Round is the most popular choice, Oval and Marquise shapes can give the diamond a bigger appearance with the same carat weight.

Lesson 8 - Setting

The appearance of a 4.5 carat diamond ring can vary greatly based on the type of band it has.

What is setting?

The part of the diamond ring that holds the diamond, called the band, is usually made of gold. You can choose from white, yellow, or rose gold. Another option is a platinum band. The setting plays a crucial role in how your 4.5 carat diamond ring looks. It's a great chance to show off your personal style. There are three common settings to choose from, and it's recommended to go with a 14k gold band regardless of which setting you like. The reason for this will be explained as you read further.
The setting or band is really important for making your diamond look bigger and better. 

Choose a 14K gold ring.

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 Choice - A Delicate Band Makes the Diamond Stand Out

According to polling, a sizeable diamond is on most women's wish list. Enhance the visual impact of a 4.5 carat diamond ring with a Solitaire setting that features a slender, delicate band. The contrast between the smaller band and the grand diamond can simulate the appearance of a larger stone. For an additional effect, opt for settings that use tiny accent diamonds along the band, adding to the ring's beauty without pulling focus from the centerpiece diamond.

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

Looking to make your 4.5 carat diamond ring appear larger? Consider a halo setting. This type of setting features smaller diamonds surrounding the main gem, which creates a beautiful effect and gives the illusion of a bigger diamond. For even more impact, you might want to go for a double halo setting. Pairing it with a thin band can make a smaller diamond look significantly larger, making it seem like a more extravagant and impressive piece.

Stay focused on the main diamond

Most women prefer a big diamond that looks really big. If your ring is too fancy or wide, it might take attention away from the diamond, making it seem smaller. If the most important thing for you is the 4.5 carat diamond ring, a simpler band might be a better choice. However, if you care more about the overall design of the ring, a fancier band could be the right one for you, but remember, this might distract from the diamond.
