Cedar Wood Oil
Nearly all emeralds are treated with a liquid or resin after cutting. The traditional way to enhance emeralds gemstonality has been to treat them with near colorless natural cedar wood oil. The refractive index of cedar wood oil is in the range of 1.495-1.510. The purpose of the treatment is to reduce the visibility of inclusions in emeralds in order to improve the appearance. If in doubt consult a reputed gem testing laboratory.
