Gemstones have been a source of fascination for Millenia, from the icy brilliance of diamond and the soft iridescence of pearl, to the deep red garnets treasured by ancient Egyptians and Victorians alike. They are used for their natural beauty in jewellery, worn for protection as talismans, associated with romance and power. They are also of scientific importance, forming over billions of years and containing secrets to the inner earth. This book examines the world's most commonly encountered gemstones, exploring their unique beauty, rarity, and durability. It reveals how these gem materials formed, where they are mined, how they are identified by their physical and optical properties, their enhancements and imitations. Travelling through each gem's history and use in adornment, it is filled with fascinating facts for the curious to the professional. With sumptuous colour photographs, Gemstones is a dazzling insight into the world of the rare and valuable.

Robin Hansen can justifiably claim to be the person who started the groundswell of interest in roots knitting patterns for mittens. When Fox & Geese & Fences: A Collection of Traditional Maine Mittens was published a generation ago, it was an instant success, and nary a knitter above the age of thirty has not heard of it. It was followed by a second, equally inspiring collection: Flying Geese & Partridge Feet: More Mittens from Up North & Down East. Favorite Mittens is a compilation of some of the most popular traditional designs from Robin's groundbreaking first two books, presenting these tried-and-true patterns in a new format, with step-by-step directions revised and updated for ease of knitting, thanks to the helpful feedback Robin has gotten from the knitters who flock to her workshops all around the country.
