Carats – Gem Weight & Jewelry

The update screwed the estimations

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.

Works well with round diamonds
