MicroWorld of Gems
MicroWorld of Gems Publications
microWorld of Gems is an extensive resource on the internal world of gemstones—for the beauty they display and the information they reveal about their identity, origin, and sometimes, treatment.
MicroWorld of Gems is pleased to represent the work of gemologist John I. Koivula, the leading authority in the world today on inclusions in gems and minerals.
John Koivula has had a passion for the science of inclusions in gems and minerals since childhood.
For him, a serious avocation led to a formal education in chemistry and geology, and subsequently, a career in gemology.
His keen interest in the microworld of gemstones has produced seminal gemological research and the development of many new and useful techniques for photomicrography of gemstones.
