Very accurate and quick
The different shapes for cuts and their estimates are helpful especially since it doesn’t need a network connection
Very handy app!
I use this constantly, and it's pretty accurate! I wish there were more stones to choose from, or a pro version for guys in the gemstones industry like me that would give the species alone as an option. Also, more stone cuts would be nice too, or different variations on cuts, like proportions above and below the girdle, double sided instead of single sided cabs an cushions, or even the ability to put in the measurements of your own unique cuts and save them for later.
I'm no expert so I can't speak to it's accuracy. But it is definitely consistent and very easy to use. Helpful for my eBay postings!
