(The Huffingtonpost) - Diamond is a beauty to behold and its uniqueness makes it easily admirable. Nevertheless, purchasing it comes with the great task of having to distinguish it from its look-alike. Diamond occurs naturally and as a result, its proof of identity needs to come from the determination of various chemical and physical properties. Some of the useful properties are such as refractive properties, conductivity, hardness and optical properties. It is important you equip yourself with basic information about diamond before going to shop for it. Aside from the fact that diamond is a major investment, there are shady retailers out there willing to prey on any innocent person’s ignorance. Having knowledge about the 4C, that is, the diamond clarity, the diamond cut, the diamond colour, and the diamond carat is essential. Here are some tests that you can carry out at home all by yourself, or anywhere that you might come across a stone that looks like diamond without engaging a gemologist.
