Optical Character

Term from Gemology industry explained for recruiters

Optical Character refers to how gemstones interact with light, which is a crucial aspect in gemology and jewelry evaluation. This term describes various visual properties of gems, including how they sparkle, their transparency, and how light moves through them. When gemologists talk about optical character, they're basically describing how a stone looks under different lighting conditions and viewing angles. This is similar to how a diamond expert might assess a stone's brilliance and fire. Understanding optical character helps professionals determine a gem's authenticity, quality, and value.
