Engagement Ring Price Calculator
Pick a stone and a size to see what buyers paid for it, or a stone and a budget to see what size it bought. Every answer is a median of real purchases on this site, 4,438 of them in US dollars, not a list price.

How the calculator works
Each answer takes the rings in the matching band (a carat band such as 1.5 to 1.99 ct, or a price band such as $3,000 to $4,999) and reports their median and middle half. A band needs at least five rings of that stone before it gives a figure. Moissanite is sold by diamond-equivalent weight, so its sizes are not comparable with diamond weights.
