Enhancement Disclosure

Ruby and Sapphires

No indication of Thermal treatment: No altered inclusion are present that would indication that heat enhancement process was applied.

HT: Enhanced by heat (no residues present in Fissures and Cavities)

HT (1): Enhanced by heat and insignificant residues (very small residues possible within fissures only)

HT (2): Enhanced by heat and minor residues (within fissures only)

HT (3): Enhanced by heat and moderate residues and present (moderate within fissures and minor to moderate in cavities)

HT (4): Enhanced by heat and significant residues present (significant within fissures and cavities)

HT(Pb): Lead-rich vitreous residues (in fissures and /or cavities)

HT(Be): There is indication of heating. Color is modified /altered by the introduction of chemical element from an external source for e.g., Beryllium.

CEE (O): Grading of Clarity Enhancement of Emeralds are specified as:

  1. None
  2. Insignificant
  3. Minor
  4. Moderate (filler mentioned if resin)
  5. Significant (filler mentioned if resin)
