Certifications Required for Emerald Fissure-Filling Disclosure

Emeralds, one of the most sought-after gemstones, often undergo treatments to enhance their clarity. The process of fissure filling involves the use of oils, resins, or colored substances to improve the gemstone’s transparency. To ensure transparency in the market, various gemological laboratories provide certification for these treated emeralds. These certifications help buyers and sellers understand the extent and type of treatment performed on a gemstone.
Importance of Emerald Treatment Certification
Certifications for emerald fissure-filling disclosure are essential to:
- Maintain transparency in the gemstone market.
- Ensure buyers receive authentic and properly classified emeralds.
- Assist jewelers and traders in fair pricing based on treatment levels.
- Comply with international gemstone trade standards.
Certification Process
The certification process involves a thorough gemological analysis that determines the type and extent of fissure filling. Below is a classification system used by laboratories like IIGJ-RLC to quantify emerald treatments:
