Birefringence

Term from Gemology industry explained for recruiters

Birefringence is a key property that gemologists use to identify and evaluate precious stones. In simple terms, it's how light splits into two beams when it passes through certain gems. Think of it like looking through a crystal and seeing double images. This characteristic helps gemologists tell real gems from imitations and is especially important when working with diamonds, rubies, and sapphires. When you see this term on a resume, it shows that the candidate knows how to use specialized equipment and has hands-on experience in gem identification.
