Book Description
Purchasing coloured gemstones can be a magical experience, filled with excitement and anticipation. But lack of information, error, or misrepresentation can make buying gemstones confusing, intimidating, overwhelming, and costly. With more varieties than ever before to choose from, including altogether new gems, revolutionary new cuts, and new ways to buy gems -- such as internet auctions and TV shopping -- there has never been a more exciting time to buy or collect coloured gemstones. But there are also new high-tech treatments and sophisticated frauds to look out for. Lack of information, error, or misrepresentation can make the thrill of buying a gem or piece of jewellery confusing, intimidating, overwhelming, and costly. Buyers need a source of expert guidance. To help you avoid the pitfalls and keep the magic, Antoinette Matlins, an internationally respected expert on buying gems, puts her insider knowledge to work for you in this easy-to-read, easy-to-use guide. Practical, comprehensive, and easy to understand, the guide offers in depth all the information you need in order to know what to look for and what to look out for, including: what qualifies as a 'gemstone'?; how to evaluate colour -- and its impact on price; deciding between a natural gem and an enhanced gem; coloured gemstone synthesis and treatment; what to ask when buying the stone; what to get in writing; how to get what you want within your budget; price guides for popular gems, opals, and synthetic stones; And much, much more!

Book Description
Morgan discusses the origin of the emerald, its peculiar structure, and its strange allure. The story weaves across several continents and thousands of years. It is a tale of conquistadors, treachery, shipwrecks, and alchemy. Along the way, we meet scientists and kings and bear witness as the great emeralds are born, mined, smuggled, cut, and sold. The book also discusses the modern art of making synthetic emeralds. From the fastnesses of Afghanistan to the steamy jungles of Colombia and Zimbabwe, from the sands of Egypt to the bitter Urals, this is the story of a stone whose strange journey reflects the yearnings, greed, passions, and longing for beauty of the human race.
