አይነት
Ultraviolet (UV) light supports gemstone evaluation by revealing hidden fluorescence, treatments, and synthetic origins through atomic excitation. Key operational ranges include long-wave UV (315–400 nm) and short-wave UV (200–280 nm).
Common Gemstone Reactions Under UV Light
Rubies: Glow vibrant red under long-wave and short-wave UV due to chromium content.
Diamonds: Frequently exhibit blue fluorescence under long-wave UV, while phosphorescence helps separate natural stones from HPHT lab-grown alternatives.
Emeralds: Clear resin or oil fillers used for fracture-filling often fluoresce yellow, green, or blue, exposing clarity enhancements.
Sapphires: Heat-treated blue sapphires can display a chalky blue-to-green short-wave UV response.
