Geographic Origin:
Niassa - Mozambique

Treatments:
Unheated with indications of clarity enhancement with oil

Gemologist's Comments on Treatments:
As a business policy, we don't stock heated, treated, or enhanced gemstones. However, some rubies 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 rubies and facilitating the cutting/polishing process.

Also, due to their natural growth conditions and recovery methods, almost all rubies 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 rubies.

While this particular ruby is unheated, indications of clarity enhancement with oil are observed.
