A Buyer's Guide to Precious Gems on Ebay



To make sure that you do not get cheated out of your hard earned money when purchasing a diamond or other gemstone on eBay, there are several ways to make sure that you are buying a real, not faux or simulated, gemstone. Before bidding on any precious gem on eBay you need to understand how the value of gemstones is determined. When considering a diamond, remember the four Cs: carat, clarity, color, and cut.

Carat is the weight of the diamond. The larger the diamond the more expensive per carat it will be. And remember that carat is about the weight, not size or diameter, of the diamond. Clarity means the size and number of traces of non-crystallized carbon in a diamond. The larger these traces and the more numerous they are the less valuable the diamond is. Diamond color grades begin with D and go through the alphabet. D graded stones shine the most and very valuable. A D grade diamond is virtually colorless. The closer the diamond is to being colorless the more rare and valuable it is.


The cut of a diamond is judged by how it refracts and reflects light; a well-cut diamond will seem brighter.
To find the diamond that fits your price range, it really amounts to finding a happy medium between the 4Cs, then deciding which factors are the most important to you. I suggest also making sure that the diamond you are considering buying has a certificate. A certified diamond is graded on the four traits I mentioned above. There will also be particulars about the diamond that are unique to it. A certificate can make you feel much more confident when deciding to purchase a diamond from a seller on eBay.
