Does anybody knows how this works ? It cost 225 gems and you get 1 gem every 12 hours
For how long ?
Thank you

In answer to some questions on the gem dispenser:
1. The item is permanent and you can collect from it forever, as long as you are in a supported version (see #4).
2. It will only hold a maximum of 1 gem. To get the most out of it, you should collect from it as close to every 12 hours as possible.
3. The gem does not expire if you do not collect it. It will just not accumulate any additional gems until it is collected.
4. It is only supported in iOS 1.7.6+. It is not supported on Android
