This edited collection is an interdisciplinary study of gems in the early modern world. It examines the relations between the art, science, and technology of gems, and it does so against the backdrop of an expanding global trade in gems. The eleven chapters are organised into three parts. The first part sets the scene by describing how gems moved around the early modern world, how they were set in motion, and how they were pulled together in the course of their travels. The second part is about value. It asks why people valued gems, how they determined the value of a given gem, and how the value of a gem was connected to its perceived place of origin. The third part deals with the skills involved in cutting, polishing, and mounting gems, and how these skills were transmitted and articulated by artisans. The common themes of all these chapters are materials, knowledge and global trade. The contributors to this volume focus on the material properties of gems such as their weight and hardness, on the knowledge involved in exchanging them and valuing them, and on the cultural consequences of the expanding trade in gems in Eurasia and the Americas.
"Gemstones of the World" is an essential resource for every hobbyist, jeweler, or jewelry maker. More than 1,500 full-color photos showcase each precious and semiprecious stone in its rough, natural, polished, and cut renditions.
A guide to the identification, structure, and uses of precious and semi-precious stones, novelty stones, agates, and crystals.
“A glittering tale of academic jealousy and ancient artifacts, The Book of Gems is a pulse-pounding adventure.” —Katherine Addison, author of The Goblin Emperor Some truths are shatterproof... It’s been centuries since the Jeweled Valley and its magical gems were destroyed. In the republics that rose from its ashes, scientists craft synthetic jewels to heat homes, power gadgetry, and wage war. Dr. Devina Brunai is one of these scientists. She also is the only person who believes true gems still exist. The recent unearthing of the Palace of Gems gives her the perfect opportunity to find them and prove her naysayers wrong. Her chance is snatched away at the last moment when her mentor steals her research and wins the trip for himself. Soon, his messages from the field transform into bizarre ramblings about a book, a Prince, and an enemy borne of the dark. Now Dev must enter the Valley, find her mentor, and save her research before they, like gems, become relics of a time long forgotten.
