How do you know when you intend to buy a diamond or a diamond jewel that the gem is corresponding to what the jeweler describes to you? What guarantee do you have that the diamond/gemstone that you are buying is natural, not synthetic? What should you know before attempting any important diamond/gemstone/jewelry purchase?.
All diamonds are not equal. When purchasing a diamond, it is important to consider its cut, clarity, color, carat weight, fluorescence, treatments, etc. These factors affect not only the appearance and quality of a diamond but also its price.
