My name is Joseph Lee. I created this site to share the tools I built when buying an engagement ring for my beautiful wife. My tools are built with a singular purpose: to make it faster to find the best diamond at the best price.

I collected diamond price data and applied cost-effectiveness concepts from economics to objectively identify the best deals.  I cross-referenced diamond measurements with proportion-based grading criteria to identify the shiniest, best cut diamonds.  And I’ve packaged all of this information into one graph to streamline the selection process.

If you have any questions or comments please email me at jlee@diamondscreener.com. I’m also /u/sproutworkshop on reddit, where I spend time helping people choose a diamond. Best of luck to you and your future fiancee!
