The Role of a Certified Gemologist All Entries
The jewelry industry is full of people who play various roles. One of the most important is the gemologist. To put it simply, a gemologist is an expert on gemstones.
What is a Gemologist?
Gemology is the study of gemstones. Gemologists must receive specialized training at an accredited institution where they learn about all of the different types of gemstones, including how to identify and grade them.
In the United States, there are gemologists who successfully complete advanced training through various institutes, earning them the titles FGA or GG. FGA stands for Fellow of the Gemological Association, a title earned by receiving a diploma from the Gemmological Association of Great Britain. The GG title is short for Graduate Gemologist.
One of the best places to receive this advanced training is through the GIA, or Gemological Institute of America. The GIA is a nonprofit institute that has become one of the most respected authorities in the field of gemological research and education.
What Does a Certified Gemologist Do?
Through specialized training and education, a certified gemologist learns how to perform multiple important tasks. They must learn how to identify a gemstone and classify it. They will be able to tell if a stone has been treated, is synthetic, or if it’s natural. They should also be able to identify the stone’s country of origin. Gemologists will also learn how to grade stones, and must also learn how to use a variety of tools that will help them with their work.
Tools of the Trade
Certified gemologists must learn to use a wide variety of specialized tools to help them with their work. Some of the tools they use include a micrometer, refractometer, polariscope, and loupe.
The micrometer helps them to determine a stone’s dimensions, while the refractometer measures the refractive index of a stone to help the gemologist better understand how a stone refracts or bends light.
Gemologists will use the polariscope to determine a stone’s optic properties. This helps them figure out if a stone is natural or synthetic. The loupe is an incredibly important tool. It is a handheld device similar to a microscope that helps a gemologist grade and identify the stone with their eyes.
