Handbook of Gemmology

The 4th edition of 'The Handbook of Gemmology' is now available for $ 49.95 USD and can be viewed on your Mac, Windows PC, iPad, iPhone, Android or online.

So what has changed?

Well the simple answer is everything!

The most radical change we have made is to make the book available to view online. Now you have the option of downloading the 'device specific' files so that you have a free-standing e-book or you can simply log in and view it on the internet without taking up valuable space on your hard drive. We want to provide you with more viewing options and make this publication more user-friendly. Since the book has more than doubled in size since the 1st edition (654 pages to 1342 pages), this is an important consideration and with more and more people having access to high-speed internet, it seemed a logical progression.

Content wise, this edition features a brand new layout that gives the book a completely different look and feel. All the information has been updated, hundreds of new photographs have been added, there is a new section on gem mining in Africa and Myanmar, new pricing comparisions for all the major gemstones and a whole new approach to identifying gemstones.

Covering all aspects of the science of gemmology and gem identification this innovative and interactive e-book features the photography of internationally renowned gemstone/mineral photographers Tino Hammid & Jeff Scovil plus some wonderful imagery by Conny Forsberg, John Dyer, David Dyer, Lydia Dyer, Priscilla Dyer, Ozzie Campos, Dmitry Stolyarevich, Arjuna Irsutti and Sergey Pryanechnikov. The Handbook of Gemmology is a must buy for any gemmologist, student or jeweller who demands the latest technology and the most up-to-date information.

Features include: State of the art 'Flipping Book' technology (Windows/Mac Versions), Powerful Search Engine, Post-its, Bookmarks, Highlighting, Hyperlinked Table of Contents, Index & Cross-References, Zoom in/Zoom out and Thumbnail Images.

The book is comprised of four sections, ‘Gemmology’, ‘Reflections', ‘Gem Identification’, and 'GEMFACTS'.

The first section covers the science of gemmology, including the chemical nature of gemstones, their physical and optical properties, basic crystallography, the absorption of light, the spectroscope, polarized light, the polariscope, pleochroism, the dichroscope, colour filters, specific gravity, luminescence, magnification, thermal conductivity, imitation, assembled and lab-created gemstones, enhancements, mining, gem cutting, coloured gemstone and diamond grading.

The 'Reflections' section includes 134 pages of photographs that capture the true beauty and talent of award winning gem cutter John Dyer.

The third section covers gem identification and includes twelve chapters covering the identification of gemstones based on their colour and transparency with a new focus on the importance of determining the optical character of a gemstone and advanced gem testing techniques.

The fourth section covers the seventeen most common gem species and varieties found in the market.
