They should know that you want the best for them, and that if you could, you would give it to them. If not, you may want to rethink the person you are about to marry. Most who have to give a cubic zirconia jewelry make the promise that a real diamond (or ring of the bride’s choice) will come within a certain amount of time. That time may be different for everyone, and whatever each couple agrees upon is just fine. What can be great about cubic zirconia jewelry is that these rings look better than ever, and no one has to know the difference. You just have to be smart when you buy one. You don’t want to buy a huge rock on one if it does not fit in with what you could really afford after a reasonable amount of saving up for an engagement ring.
