Buying any diamond jewelry piece will always lead you to knowing about the 4Cs, namely cut, clarity, color, and carat. The cut is usually the biggest deciding factor how much a diamond jewelry will cost. This is because the brilliance and fire of the stone can be dependent on how the diamond is cut. Clarity, on the other hand, refers to the inclusions or natural fingerprints on the stone. They are not typically seen by the eye — you’ll need a jeweler’s magnifying glass to see these imperfections. White or colorless diamond is considered the most expensive and rarest of all. Lastly, carat refers to the weight or size of the diamond gem. You can find diamonds here for more info.
