Gems & Gemology
Since 1930 GIA’s quarterly journal, Gems & Gemology publishes the latest peer-reviewed research on diamonds and colored stones – where they are found, their special characteristics, simulants and synthetics, treatments and identification techniques.
Each issue includes feature articles, in-depth research about gem inclusions, book reviews and the latest news from the GIA Laboratory and around the world.
GIA pursues a wide range of scientific investigations to gather and analyze data on gemstones, identifying practical solutions to gemological challenges and communicating their findings.
