8 Carat Diamond Ring Price

Diamond Education

If you have your heart set on purchasing an 8-carat diamond ring, you will quickly realize that there is a significant variance in costs.

What you will find for an 8-carat diamond price tag is dependent on many elements. One thing to know is that ‘more affordable’ options can be just as stunning as those rings that carry a higher cost, if you’re smart about where you focus your budget.

Learning all you can about diamonds and what will affect their cost can help you make the most informed decision possible. 8-carat diamond rings are an investment, and you should take the time to explore the elements here that can affect the price. 

How much does an 8 carat diamond cost?

8-carat diamonds make a stunning engagement ring choice. Some of the most beautiful selections will include brilliant round styles or cushion-cut options. So, how much is an 8-carat diamond? 

Consequently, these stones will have significant price variances. For example, the total 8-carat diamond ring price for a low-quality diamond can range from $15,000 to $20,000 per carat, making it $120,000 to $160,000. 

On the other hand, a higher-quality diamond cut will set you back between $25,000 to $45,000 per carat, giving you an 8-carat ring price between $200,000 and $360,000 overall.

With such a distinction of costs, you must know how your choices of contributing elements can make your ring fall somewhere on this spectrum. Some of these elements may be important to you, while others may not be as critical. 

Keep in mind that there are two extremes to each contributing factor, and the option you choose will alter the final cost. 

High-Priced Diamonds

Diamond prices are related to quality, which is related to rarity. Flawless clarity diamonds, or extremely white diamonds, are uncommon to find in nature – even more so at 8 carats!

As with most things, the law of supply and demand means that if supply is limited and people want to but it, prices are high.

Of course, there is a sweet spot between the most and least expensive diamond rings, where the quality, cut style deliver good value for the price point. 

Factors That Affect 8 Carat Diamond Price

Before you start budgeting for your next big jewelry purchase, finding out what will affect the price can help you prepare. As a general guideline, five elements will raise or lower the cost when purchasing a diamond. These factors include: 

  • Cut
  • Color 
  • Clarity
  • Carat
  • Certification 

While many jewelry enthusiasts are familiar with the 4 Cs of diamond buying, some also include the fifth one, certification, since it can also alter the final costs of a ring. 

Diamond shape’s effect on an 8 carat diamond price

The cut of the diamond stone is one of the significant elements affecting cost. The ten popular cut styles include: 

Some of these cuts are more popular than others, while others require more precision to make, which can both increase their prices.

Color’s effect on an 8 carat diamond price 

The color of an 8-carat diamond includes so much more diversity than you may believe. A diamond can be an entirely colorless icy white or exhibit a pale light yellow hue and anywhere in between. 

Of course, at one end of the spectrum with a completely colorless diamond, the cost will be higher than one that shows a light yellow color. On the other hand, it can be hard to tell what color grade a diamond is on its own, so side-by-side comparisons can help distinguish them. 

Clarity’s affect on 8 carat diamond price 

Clarity is what makes your diamond rare and consequently affects the price tag.

The markings that are within the stone help determine its clarity. They range from flawless to the opposite end of the scale at Included 3. So naturally, a flawless-grade diamond will be the most costly option, while an Included 3 grading is the least expensive.   


Although the certification is not an official diamond measurement, it is often a contributing factor to your 8-carat diamond ring price point. A stone that includes a certificate was assessed and graded by an independent party. These certificates can increase the value since they are a guarantee of the diamond’s quality. 

Having a diamond with the certification also ensures that you are getting what you pay for. This way, you are sure not to overpay for a stone of poor quality. Unfortunately, not everyone is an expert on diamond elements, so a certificate helps protect your investment. 

Difference Between Price and Value 

When shopping for an 8-carat diamond ring, it’s important to find a blend of the different quality factors that appeal to you and the price that works for you too.

One thing to understand is that diamonds are a natural product, each with their own quality characteristics. Choosing the lowest price diamond that hits a particular carat weight and getting ‘the best deal’ may not always be the best choice. Often cheaper stones are less expensive for a reason – they may have been shaped poorly so they are dull rather than displaying brilliant sparkle, they may face up small for their carat weight or they may include impurities that are easy to see with the naked eye. All of these would mean that a ‘cheap’ diamond isn’t actually offering good value.

Equally, high-priced diamonds may sit at the top end of the quality scales, but may have imperceptible differences compared to a ‘lower quality’ and less expensive diamond. The difference between a flawless diamond and a VS1 is so minimal that anyone without specific training cannot tell them apart, even with a microscope. Even so, the flawless stone will carry a heftier price tag, making the diamond at a lower grade level a much better value. 

Remember that ‘perfect’ 8-carat diamond rings will be pricey, while some terrific options will look identical to the naked eye and cost a lot less.
