Indications of minor clarity enhancement with oil

Gemologist's Comments on Treatments:
As a business policy, we don't stock heated, treated, or enhanced gemstones. However, emeralds invariably come into contact with oil during their life, from mining to cutting/polishing to selling. This is because oil is commonly used as a lubricant for cleaning/storing rough emeralds and facilitating the cutting/polishing process.

Also, due to their natural growth conditions and recovery methods, almost all emeralds contain surface-reaching features. Therefore, the oil may seep into these features even when not intended as a treatment.

For this reason, clarity enhancement - particularly with oil - is a common and widely accepted trade practice for emeralds.

Indications of "minor" clarity enhancement with oil are observed in this particular emerald.
