3 Main Factors Affecting 1 Carat Diamonds Price in India
4C’s of the Diamond: Cut, Color, Clarity & Carat Weight
1. Cut
The cut determines how well a diamond reflects light — influencing its brilliance. A well-cut diamond will sparkle brighter and appear larger than poorly cut ones of the same weight.
2. Color
Diamond color is graded from D (colorless) to Z (light yellow or brown). The more colorless it is, the higher its value.
3. Clarity
Clarity refers to the internal or surface imperfections called inclusions.
Grades range from Flawless (FL) to Included (I1–I3). Fewer inclusions mean better clarity and higher price.
4. Carat Weight
Carat measures the weight of the diamond. While 1 carat equals 0.2 grams, two 1-carat diamonds can differ in price depending on the other 3Cs.
Market Demand and Trends
In 2025, market trends show a rise in demand for lab-grown diamonds, making them a popular choice for their affordability and ethical sourcing. Seasonal demand (like wedding seasons) also influences the 1 carat diamond price in India.
Certification
Always look for diamonds certified by recognized authorities like GIA, IGI, or SGL. Certification ensures authenticity, quality, and transparency — key factors that impact diamond pricing.
5 Tips to Buy One Carat Diamond in India
1. Budget
Set a clear budget before starting your diamond shopping journey. Prices fluctuate based on small quality differences, so plan accordingly.
2. Four Cs
Prioritize which of the 4Cs matter most to you — for example, you might choose better cut and color over size for more brilliance.
3. Compare Prices from Multiple Vendors

4. Verify Certification
Ensure that the diamond comes with an authentic certification from GIA or IGI to verify its grade.
