Why Diamond Prices Increase Exponentially
Large diamonds are extremely rare.
- Finding a 1-carat diamond is relatively common
- Finding a flawless 5–10 carat diamond is extremely rare
Because of this rarity:
- Demand stays high
- Supply drops sharply
- Prices skyrocket
👉 This is why a 2-carat diamond can cost 3–5× more per carat than a 1-carat.
Price Per Carat Explained
Diamond pricing is usually calculated per carat, but:
- Price per carat increases with size
- Higher quality = higher price per carat
Example:
- 1 carat = ₹5 lakh
- 2 carat = ₹15 lakh (not ₹10 lakh)
Bigger diamonds are priced at a premium per carat, not just total weight.

Factors That Affect Diamond Price
1. The 4Cs (Most Important)
Cut
- Determines sparkle and brilliance
- Excellent cut = higher price
Color
- Less color = more valuable
- D (colorless) is the most expensive
Clarity
- Fewer inclusions = higher value
Carat
- Larger size = exponentially higher cost
2. Diamond Shape
- Round diamonds = most expensive
- Oval, pear, cushion = better value
3. Certification
Always look for:
- GIA (Gemological Institute of America)
- IGI (International Gemological Institute)
Certified diamonds are more trustworthy and hold better value.

Tips to Get the Best Value
1. Prioritize Cut Over Everything
A well-cut diamond looks bigger and brighter.
2. Choose Slightly Lower Color/Clarity
You can save thousands with minimal visual difference.
3. Go for Fancy Shapes
Oval or pear gives better size perception for less money.
4. Buy Certified Diamonds Only
Avoid uncertified stones—they’re risky.
5. Consider “Just Under” Sizes
Example:
- 0.9 ct instead of 1 ct
- 1.9 ct instead of 2 ct
👉 Big savings, same visual size.
