Kingk-the developer of Dream World worked with Kongregate on having the ability to ‘share’ crystals in the game via the users profile. It appears that this feature only works sporadically, some times people can share (the share button is there in the game) and sometimes it can’t.
Supposedly kingk has been in touch with Kong, but the problem still isn’t rectified. It seems that it is a problem within Kong and not Dream World. Were you aware of this problem and if so, will it be addressed?
