Today buyers cannot be sure whether or not a gemstone is man-made, if its color has been produced artificially, and if it will survive life in a piece of jewelry. This book enables gemstone and jewelry buyers to find out for themselves. A wide range of gem and ornamental materials is described, species by species, opening up the secrets they sometimes conceal, such as when they can be artificially manufactured, when they can be cleverly imitated by other materials, and when their color has been enhanced. Readers are told and shown what the tell-tale features are, and learn that while nothing is quite what it seems, there are ways in which they can spot give-away signs without needing to consult a laboratory.

The Diamond Compendium

Cunningham, DeeDee

From a pocket watch expert, a guide specifically on the intricacies of American models Many people have inherited an American pocket watch that sits gathering dust in a drawer, but they often only need a really good cleaning and some minor repairs to get them working again. Now this concise and beautifully illustrated step-by-step guide to the intricacies of American models will allow the enthusiastic amateur to rescue an old watch and perhaps pass it on to the next generation in full working order. American machine-made pocket watches first appeared in the 1850s and were so well-made that by the 1890s they had come to dominate the international watch market. The secret of their success was the range of standard sizes and readily interchangeable parts, plus the facility to be easily customized to suit the pocket (pun intended) of every purchaser, so that the man who could only afford the nickel case could be as confident as the wealthy one who chose the solid gold case that his timepiece was accurate and reliable. These very popular watches sold in their millions and have stood the test of time (pun also intended) so that they are still readily available.
