💎 What Is the Diamond Price Calculator?
The Diamond Price Calculator is a free online tool that helps you determine the total cost of a diamond based on three inputs:
- Carat Weight – the size/weight of the diamond

By entering these values, the calculator instantly outputs the Total Price, including the discount. This tool is perfect for both retail customers and diamond industry professionals who need fast and accurate price estimates.

💡 Practical Example
Let’s walk through a sample calculation:
- Carat Weight: 1.50
- Price per Carat: $5,000
- Discount: 10%
Calculation:
- Base price = 1.5 * 5000 = $7,500
- Discount = 10% of $7,500 = $750
- Total Price = $7,500 - $750 = $6,750
The calculator displays this result instantly so you don’t have to do the math manually.

❓ Diamond Pricing FAQs (15–20 Detailed Questions)
1. What does "carat" mean in diamonds?
A carat is a unit of weight used for gemstones. One carat equals 200 milligrams (0.2 grams).
2. Why does the price per carat increase with size?
Larger diamonds are rarer, so they cost more per carat. A 2-carat diamond will cost more than double a 1-carat of the same quality.
3. What affects the price per carat of a diamond?
Key factors include cut, clarity, color, and carat weight — known as the 4Cs. Brand, certification, and shape also influence pricing.
4. How accurate is this calculator?
It gives a precise mathematical total based on your inputs. However, it doesn't factor in taxes, setting costs, or certification fees.
5. Can I use this for lab-grown diamonds?
Yes. Just enter the carat and current market price per carat for lab-grown stones.
6. What’s a typical discount on diamonds?
Retail discounts range from 5%–30%, depending on the seller and time of year (e.g., holiday sales).
7. Is it better to buy by total price or price per carat?
Price per carat gives better insight into value. A lower total price may mean lower quality or smaller size.

No. It focuses purely on diamond cost. Taxes, settings, and shipping are additional and vary by seller.
9. Can this be used for colored gemstones?
Yes, if you know the price per carat. This calculator can work for sapphires, rubies, emeralds, etc.

Convert the price to USD (or your desired currency) before entering it in the calculator.
12. Is the price shown final or negotiable?
The calculator shows a total estimate. Real-world pricing may be negotiable depending on the seller.
13. How do I know the right price per carat to enter?
Check current market rates on diamond trading platforms or ask a jeweler for an appraisal.

Yes! The calculator supports carats like 0.25, 1.75, 2.03, etc.
