Gemology is a scientific field that derives from Mineralogy and one of the most important sections of Geology. So Gemology is the science that examines precious stones and anything valuable! The Anglo-Saxon term ‘’Gemmology’’ derives from the word Gem that comes from the latin term Gemma which means "Flower Blossom" or the latin word "produce". The term Gem refers to every material (precious stone, wood, shell, fossil, organic material etc) which is valuable due to its rarity, uniqueness, beauty, processing and sometimes its age)!
