7 Carat Engagement Rings March 22, 2021 – Posted in: Jewelry Blog

We are proud to present to you our unique 7 carat diamond engagement ring collection. Here at Estate Diamond Jewelry, we have been curating vintage engagement rings for over 35 years. We know how important it is to choose a special ring that your fiancée will cherish for a lifetime. That’s why we’re going to tell you everything you should know about 7 carat diamond rings before buying one. 

How Big Is a 7 Carat Diamond?

The approximate size of a 7 carat diamond is an astonishing 12.34 x 12.34 x 7.5mm. This is quite a big size for a gemstone. In comparison, a 1 carat round diamond is about 6.5 x 6.5 x 3.9mm in size. And take note that, on average, a human finger is 17mm wide. Therefore, a 7 carat ring would take up around 70% of the finger’s surface. You’ll agree this is certainly a lot of space, so we recommend sticking with one central diamond piece. This precious gemstone doesn’t need any side additions such as pavé or halo setting. 

The approximate 12.3mm diameter only refers to a round diamond ring. So if you opt for other shapes such as pear or oval, your diamond piece could end up even bigger. This is because a 7 carat diamond ring’s size can vary drastically depending on its shape and cut. 

How Much Does a 7 Carat Diamond Ring Cost?

Below is a table showing market prices for a 7 carat diamond ring. Note that the prices in this table only apply to a 7.00-carat round diamond ring. Consequently, a 7.50-carat diamond ring would cost much more. 

Color Range SI1 Clarity VS1 Clarity IF Clarity 
K Color $102,515 $127,680 $158,592 
J Color $129,801 $162,841 $199,108 
I Color $145,216 $222,796 $256,536 
H Color $171,983 $273,756 $341,761 
G Color $217,322 $329,140 $442,820 
F Color $224,931 $435,274 $567,462 
E Color $249,270 $474,747 $630,567 
D Color $269,794 $524,062 $855,624 

Undoubtedly – 7 carat diamonds are extremely rare. For that reason, you can truly consider yourself one of the few lucky ones if you find a diamond of this weight. Of course, all diamonds are precious, but the 7 carat one is truly unique. It’s actually fewer than 20 percent of all diamonds that have a true gem quality. The chances of digging up a 7 carat are super small. 

As a result, this little piece of treasure comes with a price tag. However, you could probably find a 7 carat diamond for half the price we showed in the table. But you should know these won’t be high-quality diamonds and are most likely lab-grown. 

What Determines a Diamond’s Price 

10831 Seven Carat Diamond Engagement Ring

We’re going to give you a quick overview of the different diamond price ranges. Many factors determine a diamond’s price. First and foremost, professionals examine the 4C’s thoroughly and set the price accordingly. These are the diamond’s cut, clarity, color, and carat. 

What’s worth noting is that only one of these characteristics can raise or lower a diamond’s price by thousands of dollars. It’s essential to get familiar with all the physical properties of this gemstone before buying one. 

Here’s how different carat weights can influence a diamond ring’s price. Let’s say that all six diamonds from this table are of J color and VS2 clarity. 

Carat  Approximate Price 
1-carat $5,700 
2-carat $17,000 
3-carat $37,000 
4-carat $64,000 
5-carat $107,500 
10-carat $215,000 

In the table above, you can see that a diamond of the same color and clarity can cost from $5,700 up to $215,000, with the only difference being its carat weight.

Now let’s get familiar with different color grades that influence a diamond’s price. 

The common diamond color grade goes from D to Z. The former is the perfect, colorless diamond. The latter marks a yellow or brown hue diamond. 

This being said, D, E, and F diamond grades belong to a colorless category. These are the most expensive ones. Then, G, H, I, and J belong to a nearly colorless group. Next, K, L, M show a faint category that is still rare. All other color hues from N to Z are widely available and are very light. 

You should know that you can save a lot of money by choosing an H rather than a G color diamond. These are next to each other on the grade scale, but you can barely tell the difference with a naked eye. 

7 Carat Diamond Clarity 

Diamond Clarity Chart Infograph With Inclusions

Diamond clarity is one of the 4C’s that can significantly impact a gemstone’s price. This metric tells us about any inclusions in the diamond. You can follow GIA’s clarity scale when searching for a 7 carat diamond piece. 

Know that the perfect, flawless diamond will have an (FL) next to it. However, these are extremely rare and expensive diamonds. And so are Internally Flawless (IF). When buying a 7 carat diamond ring, we recommend staying in the Very Small Inclusions (VS1 or VS2) grade. That’s because, at this point, your diamond will appear perfectly clean to the eye. Also, you can save thousands of dollars by staying in this clarity range. 

What to remember from this part: Save money on color and clarity. Go for H color and VS2 clarity for the most budget-friendly purchase that will still have a premium quality appeal. 

7 Carat Diamond Cut 

We can surely find diamonds in all different shapes. Although, the higher the diamond’s carat grade, the fewer cut choices you have. This is because 7 carat diamonds are rare by nature. You’ll even have a hard time finding a round brilliant diamond. 

Be that as it may, you should still be able to find a nice range of shapes, starting from round brilliant up to elongated ones such as pear or oval. We recommend staying with round shapes due to the huge 7 carat diamond size. Elongated shapes might look too big on smaller-sized fingers. 

Useful Technical Terms Worth Knowing 

We agree that a 7 carat diamond ring purchase is a huge investment. That’s why it’s important to arm yourself with knowledge before buying this little piece of fortune. Here are some of the most common misconceptions when it comes to technical terms related to diamond properties. 

7 Carat vs. 7 Karat 

Here’s one of the things people find most confusing. You’ve heard of the word carat in different contexts before, but you’re not sure what it means. That’s because it can have different meanings. 

A carat is a measurement unit for a diamond’s weight. One carat equals to 200 milligrams. Therefore, a 7 carat diamond will weigh around 1,4 grams. And this is pretty heavy for a diamond, considering their extremely light nature. That’s another reason why 7 carat diamonds are quite rare. 

On the other hand, karat is the measurement unit for gold purity. Pure gold will have 24 karats. However, due to its soft structure, jewelers add alloys of other materials to make it firmer. That’s how you get an 18 karat gold ring that has 25% of alloys. 

Carat Weight vs. Total Carat Weight 

Another thing you might find confusing is how to determine your diamond’s weight. Here at Estate Diamond Jewelry, we list all carat weights according to the central diamond. So by our standards, the central diamond, along with additions, makes for Total Carat Weight. 

But some jewelers will count the additional setting such as pavé or halo diamonds in the initial carat weight. We don’t believe in listing carat weight in this way. 

Diamond Size vs. Diamond Carat 

Yet another misconception is about diamond sizes. People might wrongly think that carats determine the ring’s size. However, we already explained what a carat shows – a diamond’s weight. For example, a 7 carat diamond has a diameter of 12.3mm, while a 1 carat ring will have approximately 6.5mm. However, a 7 carat diamond will weigh 7 times more – despite being only double the size. 

Why Buy a 7 Carat Vintage Ring 

Buying a 7 carat diamond ring can easily be considered a treasure hunt. Rare, unique, and expensive. We should also add another word – antique. Truly antique. So if you’re looking to buy a natural diamond of this size, you’d better stick with vintage rings. That’s because all rings from 2+ carats are extremely rare today. 

There are tons of reasons why you should go for a vintage rather than a modern ring, but just to name a few: 

1. Authenticity 

Wearing an antique ring means wearing a unique ring. We know no two fingerprints are alike – and we can say the same about vintage rings. Each ring is specially handcrafted by jewelry masters. This is because to make this ring, they use traditional tools and techniques. No machines or lasers are involved in the process. 

2. Ethical Reasons 

Ever since the 1980s, we have seen an emergence of the so-called “conflict diamonds.” These are diamonds that come from conflict zones controlled by rebel groups. These groups take over diamond production areas and sell diamonds to fund wars. This has remained a common problem even today. However, our antique rings are way older than that – leaving you with a clear conscience. With a 100-year-old ring, you won’t have to worry about it being from a conflict zone. 

3. Vintage Ring Speaks for Itself 

The sheer fact of knowing how old your ring is, is enough for it to feel dreamy. Of course, a modern ring will be there to show all your love and commitment to your girlfriend as well but, an antique ring will do all of that and more, adding an additional value of longevity. 

How to Buy a 7 Carat Diamond Ring? 

We understand that buying a 7 carat ring is a purchase that requires a lot of consideration. We’ve shown you what some of the key things to investigate are, such as the 4C’s. But there’s a lot more to the story than that. That’s why we’re giving you top advice for a successful 7 carat diamond ring purchase: 

Our Advice 

  • Firstly, do your research. Get familiar with all the physical characteristics of your potential ring. At least now you can search for anything on the internet. Leave no stone unturned. As a result, you’ll arm yourself with the knowledge that will make your ring purchase much more pleasant. 
  • Secondly, after researching the ring, start investigating your ring sellers. Again, the internet will be your strongest ally here. You can always check for Google or BBB reviews. You can also ask your friends and relatives if they have a previous positive experience with a certain retailer. Under no condition should you buy rings from an unreliable seller. No matter how reasonable their prices might seem. 
  • Once in the shop, make sure to check your ring’s documentation and certifications. Compare the ring’s characteristics with what is written on the paper. If all things match, you can proceed with your purchase. Otherwise, always ask for clarification and additional information. 
  • Then, be sure to double-check whether the diamond is a conflict one. Your seller should be able to provide you with detailed information on your ring’s origin. 
  • Finally, make sure you buy insurance for your ring. In addition, we recommend insuring all your $1,000+ jewelry pieces. You never know when you might need it. If you end up damaging your ring, or even worse losing it, you won’t have to deal with the recovery or replacement of it all by yourself. 

Customize Your Own Ring 

To make things even more special, you can design your very own ring. If you’re all about custom ordering a 7 carat diamond ring, you’ve come to the right place. 

Here at Estate Diamond Jewelry, we have a long ring handcrafting history. Our ring masters make all vintage rings in the style of the jewelry masters from the Art Deco Era. That means we don’t use modern lasers and technology, but only the special tools and techniques like the old masters. 

In short, all you have to do is send us your dream ring design. Additionally, you can include photos for higher precision. All the rest is on us. We’d send you a quote (potentially, we’ll give you a few options), and after we make an agreement, we start making your ring. First, our jewelers start handcrafting the ring, and then we set the diamond inside.
