Proportion Analysis
Proportion Analysis is a key method used in the jewelry and gemstone industry to evaluate the quality and value of diamonds and other precious stones. It involves measuring and analyzing how a stone's different parts relate to each other in size and angle. Think of it like checking the blueprint of a house - just as a well-designed house needs correct room proportions, a well-cut gem needs proper proportions to sparkle and shine. This analysis helps determine how well a stone will reflect light, which directly affects its beauty and value. Gemologists use this skill to grade stones and ensure they meet industry standards.
