Emerald Treatments

Each and every stone is enhanced to improve its overall appearance. The cavities present within the gem are often filled with a hard colorless substance. Later, they are treated with a colorless oil or wax over the surface of the stone to cover the breaks or reduce their prominence. This process is repeated after a few years as the effect of colorless oil diminishes with the passage of time. Oiling is the oldest technique used for enhancing emerald clarity. These days, modern methods are used to improve clarity. Natural resins or waxes are used to treat the stone to provide permanent protection.
