Pleochroism
Pleochroism is a special feature that some gemstones have where they show different colors when viewed from different angles. Think of it like a color-changing effect that helps gemologists identify and value precious stones. This property is particularly important in tanzanite, sapphire, and other fine gems. When someone lists this skill on their resume, it means they know how to examine and identify gems using this color-change property, which is crucial for quality assessment and authenticity verification in the jewelry industry.
