### 1/5 — Crashes

*2018-12-15*

Crashes immediately.

### 1/5 — WARNING: DO NOT BUY!!!

*2013-05-09*

WORTHLESS APP AND DO NOT BUY IT OR GET IT!!!!

### 5/5 — Diamond Pricing

*2019-01-24*

Now the bugs have been fixed, this app is awesome!  Calculates the wholesale price of “mined” diamonds AND the first and only app to calculate wholesale price of “lab grown” diamonds quickly and easily.  I love this app and recommend the 1 year subscription to keep your finger on the pulse for the latest wholesale diamond price list.

### 5/5 — Great value

*2014-06-01, version 4.2*

I use this app every day in my work as a jewellery appraiser, it gives me instant access to prices on a wide selection of stones and when I found a large stone that was not covered by the list I contacted Wayne directly and he was able to do some research in the US. Very very helpful I regularly recommend this to my friends. Used in conjunction with other sources I feel very confident  with the prices I arrive at

### 5/5 — Very useful

*2014-01-31, version 3.8*

I used this when buying a ring for my wife. Useful to compare the effect the 4 c's have on price. You enter your country's currency and vary the percentage markup to coincide with the online place your purchasing from and then start selecting.

### 5/5 — Diamond

*2013-08-07*

Awesome

### 5/5 — Excellent app

*2013-06-07*

This app was so useful, it's very accurate and I love the sub-divisions of the individual stone prices and mm for each stone. Thank you.

### 5/5 — DIAMONDMASTER

*2013-05-10*

A MUST BUY for anyone wanting to compare diamond sizes and appreciation rates! I am not aware of any other app with this capability. In doing research on the app developer it looks likes he has a strong background in the gem industry and is the founder of the Troy Diamond Report and has put together an app that both industry and lay people can use easily!  I am looking forward to being able to gain a better understanding of not only the value of any diamond purchased but also of the appreciation value attached. So happy I found this!
