Diamond Master Stone Set

These sets are used in the jewelry industry for grading diamonds based on their color.

• Comparison: The diamond being graded is compared to the stones in the master set, which represent different color grades (ranging from D for colorless to Z for light yellow or brown).
• Controlled Environment: This comparison takes place under controlled lighting conditions and often involves placing the diamond on a pure white surface to minimize external influences on its perceived color.
• Determining the Grade: The diamond is then assigned a color grade based on how closely its color matches one of the master stones.
• Purpose: Master stone sets help jewelers and gemologists accurately and consistently classify the color of diamonds, which is a crucial factor in determining their value and quality.
