If you know ANYTHING about diamonds already then this app is a waste. The "education" section is remedial at best. I learned absolutely nothing new and found a LOT of information was simply missing. It was a totally superficial attempt at "educating" the diamond buyer.
The SRP calculator is all but useless. The prices are so high above what any person (especially one concerned enough about diamond prices to buy this app) would pay, as to be absurd. From what I know, Id say the prices are 80-90% too high. I guess thats to be expected. It appears to come from the Gemalogical Institute of America - the people selling you diamonds.
In sum, this is one of the most useless apps Ive ever purchased.
