How to identify raw black diamonds "carbonado" at home set

Black diamonds, also known as carbonado, are rare and valuable gems that are often used in jewelry. To identify a black diamond at home, you can follow these steps: 1. Look for uniform color: Black diamonds have a uniform dark color without any visible inclusions or color variations. 2. Check the weight: Black diamonds are denser than other diamonds and often weigh more for their size. 3. Check for translucency: Hold the diamond up to a light source and look for any signs of transparency. Black diamonds are usually opaque and do not allow light to pass through. 4. Inspect the surface: The surface of a black diamond is often rough and porous, with a texture similar to that of pumice stone. 5. Conduct a thermal test: Heat the diamond with a lighter and observe how it reacts to heat. If the diamond changes color or cracks, it is likely not a black diamond. It is important to note that identifying a black diamond at home can be difficult and may not always be accurate. It is recommended to have a professional gemologist perform a more thorough evaluation if you are unsure of a diamond's authenticity.
