Excerpt from Precious Stones: Considered in Their Scientific and Artistic Relations, With a Catalogue of the Townshend Collection Since 1882, when the Handbook of Precious Stones was published, the volume has been several times reprinted from stereotype plates. Occasionally a few alterations and corrections were made in the text, but no opportunity occurred to improve the arrangement of the work Or to add fresh material. The present issue, however, represents a thoroughly revised edition. A large number of paragraphs have been wholly rewritten, while so many additions have been made to the accounts given of the difierent kinds of precious stones and other beauti ful minerals that the 112 pages of the original handbook have been increased to 140. Among the minerals which have now received fuller treatment may be named - diamond, sapphire and ruby, and the diflerent varieties of garnet and of zircon. But readers who desire to make themselves more intimately acquainted with the optical properties, the crystal-forms and intimate structure, the modes of occurrence and formation and the chemical composition and constitution of precious stones, will find it necessary to turn to works in which full details of these subjects are given. I n this connection may be named the treatises of Dana, of Professor Lew-is of Cambridge, Professor M askelyne and Professor M iers, for in the pages of the present handbook only such scientific considerations find place as can be easily grasped, and which, at the same time, held) to explain the beauty of precious stones and aflord methods of identifying the difierent kinds.

Gemstones have been a source of delight and fascination for many thousands of years, from the icy brilliance of diamond and the soft iridescence of pearl, to tough jade gems once used in weapons and pink topaz that was popular in Victorian jewellery. This book looks at each of the world's known types of gemstone in turn, exploring their unique beauty, rarity and durability. It reveals how each of the gem minerals forms, where they are found and mined, and how they are identified. The book also explains how to distinguish the real from the fake, as well as cutting and polishing techniques. The use of gemstones in adornment, from over 4,500 years ago to the present day, is also explored. With sumptuous colour photographs, Gemstones is a dazzling insight into the world of the rare and the valuable.

Each gem deposit-whether of primary origin in the parent rocks; or secondary as alluvial placers in valley floors, river gravels, or the sand of oceanic shelves presents an eloquent chronicle of the Earth's life story. It reveals to the expert the prodigious processes which formed the present crust of our planet, of which this volume discloses a small but exciting detail. The materials of the Earth's crust are the rocks. In this book, the author expounds on how they were formed, why they altered, why they became the cradles of precious gemstones, how they are categorized, and how they are now exploited by man. What initiates the growth of gemstones? How do they crystallize? Why do gemstones of the same species, originating from different sources, vary? What causes the occurrence of varieties? Why do diamonds, unlike other precious stones, occur not near the Earth's surface in its crust, but deep down beneath it in the upper mantle? These are only a few of the entrancing subjects discussed in this enlightening volume. The reader learns that the Earth is surprisingly alive and altering constantly-sometimes through slow and equable changes and at times by violent and tremendous cataclysms, events from which gemstones issue.
