Editorial Overview

A field-tested framework for gemology professionals.

The Handbook of Field Gemology begins with a foundational question: what is a field gemologist? From there, it builds a full mine-to-market perspective for the modern gemstone industry.

Distilling decades of expeditions and sourcing work, this book maps practical pathways from origin intelligence and field selection to value communication and market positioning.

More than a reference for origin-related laboratory work, field gemology is presented as a strategic advantage: direct source access, stronger professional identity, and a richer ability to tell the true journey of gems.
