I was just browsing The Jewelry Exchange website and saw non certified 1ct. diamonds for under $500. I have no experience dealing with diamonds, but isn''t this unheard of? What kind of problems can one expect from something like this? Does anyone have any experience with the Jewelry Exchange? I have read every article/tutorial/etc. that I could find about non certified vs. certified diamonds and what to consider when buying any diamond. If I have a ring, and I am looking for something that just looks good to the naked eye, and am not concerned with exact dimensions of the cuts, etc., do you think this is a route I should take? I am completely new to this, and just want some feedback as to the pros and cons. I don''t have a lot of money and want the engagement ring that I end up purchasing to be something I can be proud of. Any advice, insight, or opinions would be really helpful. Thanks!
