Description

Bound not for the connoisseurs or 'rockhounds,' this book is for children aged 6-13 years. With a feast on eyes, witty illustrations, through a gem-mining adventure of two exotic animals (patas monkey and matamata turtle), it explains the chemical compositions and physical properties (hardness, refraction, flaw, saturation, asterism, hue) of 18 popular gemstones, their mine locations, mastery of the cut, value criteria, popularity among the pop and cardinal jewelry clientèle. It displays variances and looks of each gems from different geographical regions. Displaying the world`s biggest ten signature diamonds (Cullinan, Orloff, Centenary, Regent, Kohi-i-Noor, Idol`s Eye, Taylor-Burton, Sancy, Blue Hope, and Hortensia) it runs their history, inclusive for Tiaras and Cameos belonging to many Queens. Equally referred to the boys and girls, basic knowledge in gems is important for the growing minds. This book is not for a 'junior gemologist.' Studying gems should be included in default in elementary education for many reasons. First and foremost, it exercises their common sense to appreciate the difference between 'good and great,' 'great and crown.' Gemology incorporates several discplines: geology, chemistry, visual arts, craft, fashion, and even alternative medicine. It is about knowing our land, its secrets and treasures. It helps our children to ponder why gems containing aluminium or cadmium cations are deposited in hydro thermally formed rhyolites, while gems consisted of iron or copper cations are set at the volcaninc base in a different location; it makes them to think of unbeatable caprice of pure carbone that makes it famously hard to convert the graphite into diamond. It offers them many 'whereabouts, and 'hows.' It also upgrades their preparation for a savvy lifestyle. It would be noble, if instead of star-war games or fantasy footballs, children and teens would spend their spare time on studying gems, uncovering their beauty and value. A wake -up call, this book also reminds us about the rare animals, which require more attention than we actually pay.
