When I examine a diamond should I use my hands or tweezers?

When examining your diamond, it's recommended that really you use diamond tweezers to be able to examine at. The reason that we don't recommend that you use your hands is because the oils on your hands are easily transferred to that diamond, and it impairs the look of the diamond. There are special tweezers that every jewellery sales professional should have at your disposal. So you should always use tweezers instead of your fingers.
