Yes. You can pay 4 € each for them from the Resources tab of your warehouse.I theorized that you could use the (currently bugged IMO) collect scrolls to force a collection from the casinos before they mature, and that this should cause them to drop crystals, but I haven't seen anyone post if this actually works or not.
