Rubies & Sapphires
by Ted Themelis This book is the product of self-supported and painstaking research work of hundreds of experiments performed by the author over the last 20 years in his thermo-chmical laboratory GEMLAB in Bangkok. This book is designed to inform you the various flux-additves used in the heat-treatment processes of rubies and sapphires carefully documented and presented in a concise and authoritative manner intended for the layman. Flux-Enhanced Rubies & Sapphires provides actual facts and observations not available anywhere else. This is the first and best reference on this topic. |

Flux-Enhanced Rubies & Sapphires is an account of the author's firsthand experiences in heat-treating rubies-sapphires with flux and additives in his thermo-chemical laboratory. This book provides a better understanding of the effect of flux on rubies and sapphires and their associated enhancement of clarity, color, luster and general overall appearance. Details on the most commonly used fluxes and the methodologies applied to the heat treatment processes are revealed. Packed with over 110 color photos offering invaluable visual support to the carefully documented text; stones before and after flux treatment, equipment, inclusions, characteristics and other features. This publication has been designed to educate the reader on the flux process applied to rubies and sapphires from the practical stand point. Hopefully this work will prevent misunderstandings, misconceptions and myths about flux-enhanced gemstones. Instead, a feast of accurate facts which are sure to assist jewelers, gem traders, gemologists and just about everyone in the gem and jewelry business. To avoid costly mistakes, formulate disclosure policy and maintain good customer relations…. You've come to the right place. |

| REVIEW:
Journal of Gemmology, Vol. 2 , April 2004 " The book describes the processes involved in the heat treatment of rubies and sapphires. This is very nearly a step-by-step recipe for the treatment as all stages are illustrated on each side of the text which occupies the centre of each page. The all-colour illustrations and the strong red page headers make the book seem quite aggressive and the effect is memorable. The text is, too, or should be as this is probably the best account so far of this type of treatment. Several authorities are cited and the dangers of doing it yourself are emphasized in a general disclaimer. There is a glossary and a short bibliography. The final part of the text deals with identifying treatment of this kind: disclosure and market value are also briefly discussed. Questions and answers cover several of the areas which gemologists could well study. M.O'D" |

REVIEW:
AUSTRALIAN GEMMOLOGIST, Vol. 22, Number 2, April-June 2003 As a book 'designed to educate the reader on flux process applied to rubies and sapphires from the practical standpoint', this book certainly succeeds; for its content is as unique and it is useful. Thank you Ted for ‘lifting the lid' on this long used and occasionally contentions value enhancement process for ruby and sapphire. Ed." |

ERRATA Page 10, left column, para 3, line 2-3: "This
chemical produced oxygen at the anode and hydrogen in the cathode"
does not pertain directly to the issues and it should be deleted.
It was a computer glitch during the typesetting process, not caught
in the final editing process. Apologies.. IMPORTANT NOTE: The Chemical Abstracts Service (CAS) registration number following the chemical formula of the chemicals described in this work is printed correctly, so the above typographic errors are immediately realized. |
