RUBY & SAPPHIRE • A Collector's Guide
(2014)

"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
