RUBY & SAPPHIRE • A GEMOLOGIST'S GUIDE
"The attention to detail is such as to make it the holy book of corundum. It simply has no comparable."
Stuart Robertson, The GemGuide
RUBY & SAPPHIRE • A COLLECTOR'S GUIDE
"Ruby & Sapphire: A Collector’s Guide is probably the most significant book to have emerged recently from the gemology world, but more importantly it transcends that genre to delight a far wider audience."
Elise Skalwold, Rocks & Minerals Magazine
"Upon opening the book, I found the photos so captivating it was impossible to start reading without first giving it a thorough peruse... Buy it, enjoy it yourself and give it away. I present an enthusiastic 'two thumbs up.'"
Jeffery Bergman, InColor Magazine
