Save hundreds of dollars when buying a diamond! Our algorithms will tell you whether you’re getting a good deal so you can purchase the best diamond you can afford.

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.

Super helpful app

I found this app super helpful when understanding what prices to expect for engagement ring center diamonds purchased online. I knew the online prices were generally lower than in store, but I wasn’t sure how much lower to expect and I didn’t want to look through thousands of diamonds and multiple sites to figure it out. I used this app and cross checked with a few sites for the settings I wanted and it seems pretty accurate so far! This is an excellent app for someone who’s planning on purchasing a diamond online and wants an estimate of what constitutes a good price.

Really useful app!

This app really came in handy when distinguishing between multiple online diamonds. There are so many choices and no scientific way of knowing what’s the best deal. This app changes all that!
