Diamond Price Guides
What diamonds actually cost in 2026, broken down by the factors that move price the most.
Why Prices Vary So Much
Two diamonds with the same carat weight can differ in price by 40% or more once cut quality, fluorescence and certification lab are factored in.
Retailer margin — not stone quality — explains a meaningful share of the remaining gap. See our full pricing breakdown for a worked example.
Approximate Price by Carat (Round, G Color, VS1, Excellent Cut)
| Carat | Natural (GIA) | Lab-Grown (IGI) |
|---|---|---|
| 0.50ct | $1,800–$2,400 | $500–$800 |
| 1.00ct | $5,500–$7,500 | $1,400–$2,000 |
| 1.50ct | $10,000–$14,000 | $2,600–$3,600 |

Frequently Asked Questions
Why does fluorescence affect price?
Strong fluorescence can make a diamond appear hazy in rare cases, which discounts price — but faint-to-medium fluorescence is usually invisible and doesn't reduce value meaningfully.
Are these prices before or after retailer markup?
These are retail price ranges as shoppers actually see them, already including each retailer's margin.
