What is a clarity characteristic?

• A. A chemical impurity that gives color.
• B. A type of optical phenomenon seen in some stones.
• C. Internal or external feature of a gemstone that helps determine its quality and establish its identity.
• D. A measurement of a stone's weight relative to water.

Answer: (C)

Clarity characteristics are internal or external features that influence how clean and transparent a gemstone appears, and they are used to assess quality and help identify the stone. Internally, inclusions like tiny crystals, gas or liquid pockets, or needle-like traces, and externally, surface blemishes such as scratches or nicks, all contribute to the overall clarity. The size, number, position, and visibility of these features determine the clarity grade, which in turn affects value. Some features can even serve as a kind of fingerprint to verify a gem’s identity. The other options describe color impurities, optical effects, or weight-related measurements, which are not what clarity characteristics refer to.
