Before you start shopping, you do need to have some information about diamonds in general. This includes knowing what the 4 C’s of diamonds are – cut, clarity, color, and carat. You should also ask to see an appraisal report on the diamond from one of the internationally recognized appraisal institutes – IGI appraisals, GIA, and EGL loose diamonds.
Another factor involved in buying best value diamonds is a money back diamond guarantee. With such a guarantee you have many benefits in that you have a period of time in which you can return the diamond for a full or partial refund. This could be because the diamond is unsuitable for your needs or you find the exact diamond at a cheaper price in another location. If you bring in proof of this cheaper price, the retailer will refund you the difference between the prices of the diamonds so that you do indeed get the best value for your money.
When it comes to colored or fancy diamonds, it is hard to determine the best value diamonds in this category. Colored diamonds are more expensive than those that appear clear or colorless. If you have plenty of money to spend on such a purchase and want the best that money can buy, a red or green diamond could cost you as much as $1 million per carat. Purple diamonds range in price from $500,000 to $700,000 per carat and pink diamonds usually start at $100,000 per carat.
