Wade is a scientific publication written in the early 20th century. The book serves as a comprehensive guide for jewelers and enthusiasts seeking to understand the properties, identification, and valuation of precious stones. It aims to empower readers, especially those in the gem trade, with the necessary knowledge to distinguish genuine gemstones from imitations and synthetics. The opening of the text establishes the author's intent to blend practical trade knowledge with scientific principles, making gemology accessible even for those without formal training. It discusses the increasing sophistication of gem consumers and the corresponding need for jewelers to enhance their understanding of gems to avoid pitfalls in sales and appraisals. The author emphasizes a systematic approach in learning to identify different stones based on their unique properties, starting with fundamental concepts such as refraction and hardness, and aims to assist those who feel overwhelmed by the scientific aspects of gemology.
