How Much Is An 8 Carat Diamond?

Diamonds are the most popular gemstone in the world. Whether you’re looking for a diamond engagement ring or just want to buy a diamond necklace, they have become an essential part of modern life.

Diamonds come in all shapes and sizes, but one of the most popular is the 8 carat diamond.

So, how much does an 8 carat stone cost? To find out we need to know some factors that affect its price such as cut, clarity and color grade.

In this blog post, we’ll be looking at that and more information to help you purchase jewelry with ease.

What is an 8 Carat Diamond Worth?

An eight carat diamond is a large stone, so it will naturally cost more than smaller diamonds. The price can range from $12,000 to $40,000 per carat depending on the factors that affect its value such as cut and clarity grade.

In general, you’ll pay around $12,000 and higher for an eight carat diamond.

What Affects the Price of an 8 Carat Diamond?

The price will vary depending on factors such as cut and clarity grade. An eight carat round brilliant has to be very high quality to justify its cost because it is so large. It should have excellent proportions with good symmetry in order to make up for the extra weight.

This type of diamond that is very light in color and will be priced lower than a similar one with richer colors because it requires less of the expensive gem to produce its sparkle. 

That said, here are some of the factors that contribute to the price of an 8 carat diamond:


A high quality cutting for an eight carat round brilliant with excellent proportions and symmetry will increase the cost. The best cuts preserve light and allow for more brilliance.


The color of the diamond will also influence the price. A clear, white diamond with no noticeable flaws (inclusions) and a good cut will cost more than an off-colored stone such as gray or brown because it is easier to produce in large sizes.

Carat weight

A diamond with a higher carat weight is likely to cost more than one with a smaller carat weight as the latter is assumed to be less appealing.

Knowledge Level

You’ll see the wide range in prices for diamonds with different grades of quality because there are so many factors to take into account when making your purchase decision.

Research shows that most people spend an average of $40,000 for an eight-carat diamond.

Some people may not be able to afford a diamond at this size, but they could choose to purchase one with fewer carats or less clarity instead. It is also worth noting that the price will vary depending on where you buy from and what type of diamond you are looking for.


A high clarity grade for a round brilliant will increase cost because it is rare to find so many imperfections that do not affect appearance. Diamonds should be assessed by their eye-clean status which means they have no inclusions that can be seen by the naked eye.

As you can see, the price of an eight-carat diamond will vary depending on many factors. It is impossible to predict how much a certain stone would cost because it could be anywhere from $1,000 – $100,000 or more based on your budget and preferences.

How Can I Know the Value of My 8 Carat Diamond?

The price of a diamond is largely dependent on its size, cut, clarity and color – just as explained earlier. When you are ready to sell your eight-carat diamond for cash as opposed to selling it back to the jeweler where you bought it from, there are many factors that will affect how much money you get in return.

The gemologist who appraises your diamond will look at its clarity and color, but the most important factor is going to be size.

The weight of a carat (ct) is measured in metric units, so that means you’ll need to know how many grams it weighs first before converting it into what we call ‘carats’. Most eight-carat diamonds weigh around 1.6 grams. As for its worth, you should be able to sell an eight-carat diamond with a good cut grade score of H or better at around USD $20,000 dollars per carat (ct).

Here are more tips that you can employ to determine the value of an 8 carat diamond – or any other diamond:

The Cut and Size of Your Diamond

The cut of an eight-carat diamond is very important because it determines how much light enters the stone and then reflects back out. A valuable quality about diamonds that are not well cut is that they can scatter light in a way which creates more fire, but this also makes them look less clear. The size of your diamond will affect its price.

A diamond of eight carats will have a smaller diameter than one with six or seven. The price for an eight-carat diamond is also going to be higher because it takes more material and workmanship. As your size goes up, so too does the cost in dollars and time.

The Quality

An expensive gemstone like a diamond is often judged by its clarity or lack thereof. The higher the clarity, the more valuable it will be – but there are other factors to consider as well.

The GIA grades diamonds on a scale of D (absolutely flawless) up through I-J, which includes visible inclusions that may not affect their beauty and value. Tougher to get is the next grading scale which goes from SI-I, and these diamonds are even more expensive.

There’s also a color grade that ranges from D (colorless) up through H (neon yellow). The price for each will vary depending on how light reflects off them when they’re viewed in person or online under different lighting.

The most expensive diamonds are ones that have the perfect clarity and color. Imagine a black diamond: these stones can be worth millions of dollars because they’re so rare.

Tips for Buying Jewelry

You can find a wide variety of rings on the internet from local retailers, jewelry stores and diamond dealers that will allow you to choose the perfect one based on your budget.

  • One-way people save money on wedding bands is by buying them together in the same place at different times; this cuts down on costs like shipping fees and exchange rates. 
  • A matching band should be made out of similar materials with delicate detailing so they match perfectly, but don’t need to have exactly matching gems embedded in them.
  • The best way to make sure that you’re buying a high-quality diamond is by looking for the four “C’s”: cut, clarity, carat weight and color. These will help determine how valuable your stone is.
  • If you are wearing diamonds as part of an engagement ring or something else where it won’t be in contact with water, lotion or other jewelry on the hand then consider getting non-diamond stones because they might not need any special care and can last longer than regular diamonds do. 
  • We suggest finding out what type of metal work goes into making the setting before purchasing a gemstone so it doesn’t get scratched up within hours of coming home from the store!
  • Lastly, a good quality natural ruby will last a lot longer than an inexpensive synthetic ruby will, and the quality of materials it is set in can also make a difference.

You should always take your time to find reputable jewelers who are certified gemologists with experience dealing in high-end jewelry! This way you know that they have been trained properly and won’t sell you anything low-quality or fake.

You want someone who knows what he/she is talking about when it comes to gems because these things can be very expensive and if something goes wrong there’s no one else responsible but yourself for purchasing it!


A diamond ring is worth more than just the size of a diamond. Picking out an engagement or wedding band to match your perfect stone can be tricky and require some time spent looking for the perfect setting.

Rings aren’t created equal, so it’s best to shop around for one that will have you falling in love at first sight!
