Diamonds are valued for their unique combination of beauty, durability, and rarity. While there are several factors that contribute to a diamond's value, the primary drivers that determine the value of a diamond are the 4 C’s which we cover below.

The 4 C’s and Diamond Pricing

This visual appearance is determined by a combination of the diamond's cut, color, clarity, and carat weight.

Here is a brief explanation of each of these factors:


The cut of a diamond refers to its proportions, symmetry, and overall finish. A well-cut diamond will reflect light in a way that maximizes its brilliance, fire, and scintillation.


The color of a diamond refers to the presence or absence of color in the stone. The most valuable diamonds are completely colorless, but some diamonds with a slight tint of color can still be highly valuable.


The clarity of a diamond refers to the presence or absence of internal or external blemishes or inclusions. A diamond with fewer blemishes or inclusions will be more valuable than one with more.

Carat Weight

The carat weight of a diamond refers to the weight of the stone, with one carat equaling 0.2 grams. Larger diamonds are typically more valuable than smaller ones.

While all of these factors are important, the overall visual appearance of a diamond is considered the most important attribute because it is what gives the stone its unique beauty and appeal. 

Even a diamond with excellent cut, color, clarity, and carat weight may not be valuable if it does not have a desirable visual appearance. Therefore, when shopping for a diamond, it's important to focus on the overall visual appearance of the stone, rather than any individual factor in isolation.

Lab Grown Diamond Prices vs Natural Diamonds

The prices of lab-grown diamonds and natural diamonds can vary depending on several factors such as the diamond's carat weight, cut, color, and clarity, and where you purchase it from.

Generally speaking, lab-grown diamonds are less expensive than natural diamonds of comparable quality. This is because lab-grown diamonds are produced in a controlled environment in a laboratory, which allows for more efficient production and lower overhead costs. 

Additionally, lab-grown diamonds do not have the same rarity and perceived value as natural diamonds, which can affect their pricing.

For example, a one-carat natural diamond of good quality (color G, clarity VS2) can cost anywhere from $4,000 to $8,000, while a comparable lab-grown diamond can cost around $2,000 to $4,000. However, it's important to note that the price of a diamond can also depend on market demand and other factors.

Ultimately, whether you choose a lab-grown or natural diamond will depend on your personal preferences and values. Some people prefer natural diamonds for their rarity and perceived value, while others prefer lab-grown diamonds for their affordability and sustainability.

7 Tips on How to Save Money When Buying a Diamond

If you're looking to buy a diamond, here are some tips that can help you save money.

  1. Determine what you need: Before you start shopping, decide what you're looking for in a diamond. Consider the 4 Cs of diamonds: carat weight, cut, color, and clarity. Determine which of these factors are most important to you and focus your search accordingly.
  2. Shop around: Don't buy the first diamond you see. Shop around and compare prices from different jewelers. Look for reputable sellers with good reviews.
  3. Consider a lower carat weight: The price of a diamond increases exponentially with its carat weight. Consider a diamond that's just below the carat weight you originally wanted. The difference in size may not be noticeable, but the savings can be significant.
  4. Choose a lower clarity grade: Most inclusions in diamonds can't be seen with the naked eye. Consider a diamond with a lower clarity grade than you originally wanted. Again, the difference may not be noticeable, but the savings can be significant.
  5. Consider a different shape: Round diamonds are the most popular and therefore the most expensive. Consider a different diamond shape, such as princess, cushion, or oval. These shapes can be just as beautiful and cost less.
  6. Buy online: Online diamond sellers often have lower overhead costs than traditional brick-and-mortar stores, which means they can offer lower prices. Just be sure to buy from a reputable seller with good reviews. TIP: There are retailers that specialize in the secondhand market where you can buy previously owned diamond engagement rings.
  7. Consider a lab-grown diamond: Lab-grown diamonds are a more affordable and sustainable alternative to natural diamonds. They're virtually identical in appearance and quality to natural diamonds but cost significantly less.

Remember, a diamond is a significant purchase, so take your time and do your research before making a decision. By following these tips, you can save money without sacrificing quality.
