Buying a diamond is one of the most exciting yet challenging decisions. Whether you are purchasing an engagement ring, investment-grade diamond, or simply comparing prices, knowing the accurate diamond price is crucial.

To simplify this process, we created the GIA Diamond Price Calculator. This easy-to-use online tool helps you quickly estimate the total diamond price and shows how much you can save with discounts. With just a few clicks, you can determine the exact cost of a diamond based on your inputs.
In this article, we’ll guide you through everything you need to know about the GIA Diamond Price Calculator, including how to use it, real-life examples, benefits, and FAQs.

Example Calculation
Let’s say you want to calculate the price of a 1.50-carat diamond priced at $7,000 per carat with a 5% discount.
- Carat Weight = 1.50
- Price per Carat = $7,000
- Discount = 5%
Step 1: Multiply Carat × Price per Carat
1.50 × 7,000 = $10,500 (original price)
Step 2: Calculate Discount Amount
5% of 10,500 = $525 saved
Step 3: Final Price
10,500 – 525 = $9,975
✅ The calculator instantly displays:
