Diamond Value Estimator
Use this calculator to estimate the value of a diamond based on its 4 Cs (Carat, Cut, Color, Clarity) and a base market price per carat.

Understanding Diamond Value: The 4 Cs
The value of a diamond is primarily determined by what are known as the "4 Cs": Carat, Cut, Color, and Clarity. Our Diamond Value Estimator uses these factors, along with a base price per carat, to provide an approximate valuation.
1. Carat Weight
Carat is the standard unit of weight for diamonds. One carat equals 200 milligrams. Larger diamonds are rarer and generally command higher prices per carat, not just higher total prices. For example, a 2-carat diamond will typically cost significantly more than two 1-carat diamonds of similar quality.
2. Cut Grade
The cut of a diamond refers to how well its facets interact with light. It's often considered the most important of the 4 Cs because it directly impacts a diamond's brilliance, fire, and scintillation. A well-cut diamond will reflect light optimally, appearing more vibrant and sparkling. Cut grades typically range from Excellent to Poor, with Excellent cuts maximizing light performance.
3. Color Grade
Diamond color is graded on a scale from D (colorless) to Z (light yellow or brown). D-grade diamonds are the rarest and most valuable, possessing no discernible color. As you move down the scale, the diamond exhibits more yellow tint. While colorless diamonds are highly prized, near-colorless diamonds (G-J) can still appear white, especially when mounted, and offer excellent value.
4. Clarity Grade
Clarity refers to the absence of inclusions (internal flaws) and blemishes (external flaws). The GIA clarity scale ranges from Flawless (FL) to Included (I3). Flawless diamonds are exceptionally rare. Most diamonds have some inclusions, but many are microscopic and do not affect the diamond's beauty or durability. Diamonds with clarity grades of VS1, VS2, SI1, or SI2 often represent excellent value, as their inclusions are typically not visible to the naked eye.
Base Price per Carat
The "Base Price per Carat" is a crucial input that reflects current market conditions and the general pricing structure for diamonds. This value can fluctuate based on global demand, economic factors, and specific market trends. You can often find average base prices by consulting industry reports or reputable jewelers.
How the Calculator Works
Our calculator takes your specified Carat Weight and multiplies it by the Base Price per Carat. This base value is then adjusted by multipliers associated with your chosen Cut, Color, and Clarity grades. Higher grades in Cut, Color, and Clarity result in higher multipliers, increasing the estimated value.
Important Considerations
This calculator provides an estimation. Actual diamond prices can vary significantly due to many factors not accounted for here, including:
- Fluctuating Market Conditions: Diamond prices are dynamic and can change based on supply and demand.
- Certification: Diamonds certified by reputable laboratories (like GIA, AGS) often command higher prices due to guaranteed quality.
- Fluorescence: Some diamonds exhibit fluorescence under UV light, which can affect value.
- Shape: Fancy shapes (e.g., oval, pear, emerald) can be priced differently than round brilliant diamonds.
- Retailer Markup: Different jewelers will have varying markups.
- Specific Inclusions: The type, location, and visibility of inclusions can greatly impact value, even within the same clarity grade.
For a precise valuation, always consult with a certified gemologist or a trusted diamond expert.
