This is a truly beautiful book, filled with breathtaking pictures and exquisite stories and information. A brilliant reference for any gemmologist in love with emerald.

Read about the people, the miners, the personalities and adventurers – each caught in the allure of this exotic green stone! Rather than a mere introduction to emeralds, this book is a grand introduction to the royal view that a connoisseur takes on the subjects of color, gem appreciation and rarity.

There is information here for a gemologist to rise to the level of connoisseurship in emeralds. But beginners will find this book an expansive and informative read – one that celebrates as well as explains. The final chapters carry the mind and heart to territory that is both thought provoking and passionate – unusual for a gemological book, but timely and fitting.  CURRENTLY NOT AVAILABLE
