Gemmologists' Compendium - Robert Webster FGA

Now in its seventh edition, this book has long been regarded as the bible for both professional and amateur gemmologists, as well as retail jewellers.

Originally written by Robert Webster, a renowned expert who devoted much of his life to gemmology and spent twenty-five years at the London Gem Testing Laboratory, the volume has been thoroughly revised and updated by E. Alan Jobbins, former Keeper of Minerals and Gemstones at the Geological Museum in London for thirty-five years.

The first part of the book offers a comprehensive glossary covering every aspect of gemstones and related terminology. The second part explores topics such as synthetic and manufactured gems, gem enhancement techniques, and essential precautions for preventing damage during jewellery manufacture, repair, and cleaning.

It also includes extensive tables detailing the physical properties used in gem testing, sources of gem materials, and the various cuts that best display their beauty. Fifteen pages of full-colour photographs aid in the identification of inclusions, complemented by a range of helpful conversion tables.

Widely acknowledged as one of the most valuable reference works in the field, this book remains an indispensable companion for every gemmologist.
