The Diamond Search Engine

The smart way to find your diamond

  • Diamond Price Calculator

    Diamond prices change daily so we created a diamond price calculator that determines the fair price for any stone based on the live market prices available from top online jewelers.

  • Diamond Search Engine

    Our diamond search engine sifts through over 400,000 diamonds daily from top online jewelers including Blue Nile, Do Amore, Ritani and Whiteflash.

  • Diamond Comparison Report

    Compare up to four diamonds based on price and quality to see which our algorithm ranks as the top pick.

  • Diamond Price & Quality Check

    Run any diamond (online or from your local jeweler) through our price & quality check to identify problematic inclusions and see our fair price estimate.

“StoneAlgo helps even the most novice diamond hunters become functional enough to make informed and decent decisions on such an important and emotional purchase.”
