Field Gemology: From Mine to Market

In January 2025, GUILD Gemology Education embarked on an extensive field research expedition, with Dean Andrew Lucas and GUILD Gem Laboratory President Ms. Liu Lihong leading the team to explore jadeite sources in Guatemala and Myanmar. This comprehensive field study brought invaluable first-hand knowledge of jadeite mining operations and market dynamics.

Guatemala: Discovering Alternative Jadeite Sources

Geological Exploration

Guatemala represents one of the world's lesser-known yet significant jadeite sources. The GUILD team conducted extensive fieldwork in:

Mining Region Visits

  • Active jadeite mining sites in the Motagua River valley

  • Environmental and sustainability considerations

Jadeite Characteristics
Guatemalan jadeite exhibits distinctive features:

  • Rich green colors, ranging from apple green to emerald green
  • Unique blue-green varieties ("Olmec Blue")
  • Generally fine-grained texture
  • Historical significance dating back to Mayan civilization

Cultural and Historical Context

The team explored Guatemala's rich jade cultural heritage:

  • Ancient Mayan jade carving traditions
  • Archaeological significance of historical jade artifacts
  • Modern revival of jade craftsmanship
  • Integration of traditional and contemporary design
