Dichroscope

Term from Gemology industry explained for recruiters

A dichroscope is a simple but important tool used by gemologists and jewelry professionals to identify and evaluate gemstones. It helps determine if a stone shows different colors when viewed from different angles (a property called pleochroism). This tool is particularly useful when authenticating certain gemstones like sapphires, rubies, and tanzanite, as it can help distinguish natural stones from synthetic ones. Think of it as a special magnifying device that helps jewelry experts verify the authenticity and quality of gems.
