## Most critical reviews (4 lowest-rated)

### 4/5 — Mozo (GIA G.G.)

*2011-12-14, version 1.7.2*

This app is not bad and got common info about gem stones. It can estimate diamond/colored stones weight just by keying in stone's dimension. The list of birth stones is convenient too. Basically, what this app serves can be integrated in GIA gemological system. That's another advantage. However, the info about colored stones is not adequate. We need more species and variety. As a G.G., you are supposed to compile a more complete database. Cell phone is so advanced nowadays, I don't think that memory size would be a problem. Hope the author will improve it very soon. After all, it costs 20 bucks, and it should provides more data which can compare with its price.

### 5/5 — First rate app

*2013-09-19, version 4.0.1*

This app has helped me with numerous sales and stone weight estimates. Beautifully written app

### 5/5 — Well done!!

*2013-09-01, version 3.0.7*

Incredibly useful and brilliantly executed.  Strong kudos to the developer!

### 5/5 — Excellent portable gemologist's tool

*2011-11-19, version 1.7.2*

The features in this app enable a gemologist or appraiser or gem buyer to make weight decisions and some separation decisions using this neat little portable app -- all on an iPhone, without the need to carry a laptop.

It is worth the price based on the number of goodies that are in it.
