### 1/5 — Update problem

*2026-06-02*

The update screwed the estimations

### 4/5 — Very handy app!

*2012-09-10*

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.

### 4/5 — Good ap to have when in doubt

*2012-03-19*

Works well with round diamonds

### 5/5 — It is really useful for all the functionality it has

*2026-10-22*

I’m amazed at how accurate is and how much I needed this when I bought it it’s really useful that day

### 5/5 — Works very well with advanced

*2026-10-12, version 9.1*

It has species as well as other features and many more types of gym

### 5/5 — Very accurate and quick

*2018-07-25*

The different shapes for cuts and their estimates are helpful especially since it doesn’t need a network connection

### 5/5 — Thumbs up

*2014-02-20*

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!

### 5/5 — Great!

*2013-04-20*

Works fine for round cut calc on the go but seems to under-carat marquise diamonds by about .05
