Diamond Price Predictor

This app calculates the approximate price of a loose diamond using advanced statistical modeling by comparing it to a database of over 60,000 diamonds.

This allows you to find underpriced diamonds and avoid getting ripped off by overpriced ones. Just enter the characteristics of the diamond you’re considering, and Diamond Price Predictor will tell you the approximate fair market value of comparable diamonds. While many other “calculators” will output a price and happily send you to a shopping link, we have no commercial relations with any jewelry sellers. We have independently compiled our database from across multiple online retailers and have no conflicts of interest.
