It's a bug. You have to wait until the 24 hours is up, then you have to close and restart your app. If you close and restart before the 24 hours is up, it will still be grayed out so unfortunately you have to remember when you gifted the gems and then restart the app accordingly. It's been happening to me since the first day I started playing DV.
