If you are thinking about buying a diamond ring for your fiance, you may have heard that you should spend about two times your monthly paycheck. This is really just an old guideline.  Or you might be trying to spend as little as possible, even trying to look for wholesale diamond rings. But in reality, spend as much as you comfortably can without going into debt.  Diamonds will only appreciate in value, unlike a car or similar purchase that depreciates after you buy it.  If you talk with someone who purchased a diamond ring 20 years ago, you will probably find that a similar ring would cost five or even six times as much in today’s market.  So, you can think about it in terms of an investment in diamonds and an investment in your future.
