The Diamond 4 C's :
How it Impacts the Value of a Diamond

The process of determining the value of a diamond always starts with proper diamond authentication.

After a diamond is authenticated, the value is assessed based on the diamond 4 C’s—Cut, Color, Clarity, and Carat (Weight)—which together determine its worth in the market.

When it comes to selling a diamond, understanding its value is key.

Whether you’re considering selling a family heirloom, an unused piece of jewelry, or a diamond you no longer need, our guide will help you understand these essential factors. This knowledge empowers you to make informed decisions and ensures you get the value your diamond truly deserves.

Let’s explore what makes your diamond unique and valuable.

Diamond Carat Weight

Carat weight is a significant factor in determining the value of a diamond, as it directly influences the perceived size and rarity of the stone.

Larger diamonds are typically more visually striking and sought after. As the carat weight increases, the diamond appears larger, which can enhance its desirability.

The price of diamonds does not increase linearly with carat weight. Instead, the price per carat typically increases as diamonds reach certain weight milestones (e.g., 0.5 carats, 1 carat, 2 carats). This is known as the “carat jump,” where a diamond weighing just over a whole carat may cost significantly more than a slightly smaller diamond (e.g., 0.90 carats).

Also, the availability of diamonds decreases as their size increases. While smaller diamonds (under 1 carat) are relatively common, larger diamonds (over 2 carats) are much rarer. This rarity increases the value of larger diamonds significantly.

Determining the value of a diamond

Diamond Cut Grade

The cut of a diamond significantly affects its quality of light return or sparkle as it determines how well a diamond reflects and refracts light. 

A well-cut diamond maximizes light performance, resulting in greater brilliance (the brightness of the diamond) and fire (the dispersion of light into various colors). Poorly cut diamonds may appear dull and lifeless, significantly reducing their appeal and value.

The cut grade takes into account the diamond’s proportions, symmetry, and polish. Ideal proportions allow for optimal light entry and exit, enhancing the stone’s visual appeal. Diamonds that are cut too shallow or too deep can lose light, leading to a decrease in their value.

Other elements that are considered when assessing the value of a diamond are older styles of cut, or irregular cuts. 

Diamond Clarity Grade

The clarity of a diamond is a critical factor in determining its value, as it refers to the presence of internal or external imperfections, known as inclusions and blemishes.

Diamonds with fewer inclusions and blemishes are rarer than those with more visible imperfections. As the number of inclusions decreases, the value increases.

For instance, diamonds graded as Flawless (F) or Internally Flawless (IF) are exceptionally rare, making them more valuable than those with visible inclusions.

Clarity affects how light interacts with the diamond. Higher clarity diamonds allow more light to pass through and reflect, enhancing their brilliance and sparkle. Lower clarity diamonds may have noticeable inclusions that can obstruct light and reduce the overall visual appeal, thus decreasing their value.

Diamond Color Grade

Another crucial factor we consider before providing a loan on your diamond is its color grade.

Colorless diamonds, graded as white, are considered of the highest quality and fetch significantly higher values than diamonds of other color grades.

Diamond Shape

Certain shapes like Round and Oval are of higher value when compared to other shapes.

Due to changing tastes over time, some diamond shapes that were once very popular have also fallen in value as demand has declined.

Selling a diamond is a significant decision, and understanding the diamond 4 C’s as per the GIA Grading Scale is a powerful first step toward making it with confidence.

The same holds true you get a quick loan by using your diamond as collateral.
