Introduction
A 2.5 carat diamond is considered to be a large diamond, with a weight of 0.50 grams or 500 milligrams. The average cost of a 2.5 carat diamond ranges from $10,000 to $20,000, depending on its quality, cut, color, and clarity. However, the actual cost of a 2.5 carat diamond will vary greatly depending on these factors.

Factors That Impact the Price of a 2.5 Carat Diamond
The four Cs – cut, color, clarity, and carat weight – are the main factors that determine the overall value of a diamond. Let’s take a closer look at each of these factors.
The Quality of the Diamond
The quality of a diamond is determined by its cut, color, and clarity. The better the cut, color, and clarity of a diamond, the more valuable it will be. A diamond’s cut is determined by how well the facets of the diamond interact with light, while its color is determined by the amount of yellow or brown hues it contains. The clarity of a diamond is determined by the number and size of any imperfections it contains.
The Cut of the Diamond
The cut of a diamond determines its brilliance, or the way light reflects off of it. The better the cut, the more sparkle and fire the diamond will have, which can significantly increase its value. The most popular cuts for a 2.5 carat diamond are round, princess, oval, and cushion.
The Color of the Diamond
The color of a diamond is determined by its hue, which can range from colorless to yellow or brown. The more colorless the diamond, the more valuable it will be. Colorless diamonds are graded on a scale from D (colorless) to Z (light yellow or brown). A 2.5 carat diamond typically ranges from D to J on the color scale.
The Clarity of the Diamond
The clarity of a diamond is determined by the number and size of any imperfections it contains. The fewer and smaller the imperfections, the more valuable the diamond will be. A 2.5 carat diamond usually ranges from Internally Flawless (IF) to Slightly Included (SI2) on the clarity scale.

The Difference in Quality and Cost of a 2.5 Carat Diamond
The difference in quality and cost between low-cost and high-cost diamonds can be significant. For example, a low-cost 2.5 carat diamond may have a poor cut, a lower color grade, and a lower clarity grade, while a high-cost diamond may have an excellent cut, a higher color grade, and a higher clarity grade. This difference in quality can significantly impact the overall cost of a 2.5 carat diamond.
The Differences in Quality Between Low-Cost and High-Cost Diamonds
Low-cost diamonds tend to have a lower cut, color, and clarity grade than high-cost diamonds. Low-cost diamonds may also have visible inclusions, or flaws, that are not present in high-cost diamonds. As a result, low-cost diamonds tend to be less brilliant than high-cost diamonds.
How These Differences Impact the Cost of a 2.5 Carat Diamond
The difference in quality between low-cost and high-cost diamonds can have a significant impact on the cost of a 2.5 carat diamond. For example, a low-cost 2.5 carat diamond may cost around $10,000, while a high-cost 2.5 carat diamond may cost up to $20,000 or more. The cost difference between these two diamonds can be attributed to their differences in quality.
