My boyfriend and i cannot afford a 'great' engagement ring and out jeweler said that an option for us is a 'fake' diamond.. she used another name for it and now we cannot remember what is was. We want to know so we can do some more research on it. We would hate for it to turn out to be a horrible mistake that we went the route of purchasing this 'fake' diamond. FYI: She DID NOT call it a 'Cubic Zirconia'. Anyone know another name(s) for a 'fake' diamond?? Please help. Thank you all! :)
