Clarity Grading
Clarity Grading is a fundamental process in the jewelry and gemstone industry where experts assess how clear or clean a gemstone is from imperfections. It's like giving a quality score to a diamond or other precious stone based on how free it is from internal marks or external blemishes. This skill is essential in determining a gem's value and is one of the "4 Cs" (Cut, Color, Clarity, and Carat) used in the diamond industry. Professionals who perform clarity grading use special equipment like microscopes and loupes (special magnifying glasses) to examine stones in detail.
