"I read your book on Mogok district and I want to congratulate you for the
hard work. Because it was not easy to synthesize all these data.The illustration in color prints is perfect and the text is of high interest for a zone of high interest but closed to foreigners... I am sure that your book will be cited for ever as for the book published by Iyer (1953). Congratulations.." -Dr.G. Giuliani, IRD et CRPG/CNRS Centre de Recherches Pétrographiques et Géochimiques, Vandoeuvre-lès-Nancy, France, (March 2008)

"I have safely got your book and I am very happy to have ordered it. It is an excellent and very detailed description of this important mine-site and the layout is very good, too. The language is most readable, no complicated explanations, many very descriptive micro- and other photos. The maps are very informative. Most of them I have never seen before. The descriptions of the different mines with their specific gemstones is absolutely new for gemologists who have never had the chance to visit Mogok, nor may these descriptions be found by keen gemmologist in former books in libraries of the world. It will take time to digest what you and your son have worked out and written in such a masterly way not only for me, but also for all gemmologists. My congratulation, dear Ted, this book is a masterpiece of you. Congratulation also to your son who did support you superbly. Now, I wish both of you some days of rest. And I am sure, this volume will be bought by all serious gemmologists and libraries of the world. Three cheers for you!!! - Dr. J. Ponahlo Univ. of Vienna, Austria, Febr.2008

"...there are some fabulous photos! And it really opened my eyes to the incredible variety of minerals found in the Mogok area. Great specimens are shown and extensive research has been done by Mr. Themelis. The book is very approachable for the non-mineralogist, yet a great source of inside information for those in the field . It's not just informative about the gems and mines, but shows the human factor involved. It is a must for any gem library. "- Bear Williams, Jefferson City, MO, USA, March, 2008

"Your comprehensive book "Gems & Mines of Mogok" is a unique book about a gem mine, covering all aspects, in particular when it includes the king of the gems, the Burmese ruby. I liked very much your geological part and the genesis of Mogok gems. I am sure that this book is an achievement of a dream by you, and the trade in general benefit from your knowledge." -Israel (Eli) Eliezri, Tel-Aviv (Israel), Febr.2008
