Treatments are applied to all Emerald Gemstones
Palm Resign is also called Palma. It’s a type of oil like treatment which is used in place of Cedarwood oil. This kind of treatment is not permanent because it leaves a milky white scrap. It has not been considered an acceptable treatment, but still, it is used.
Cedar Wood Oil
Many years ago, Greeks started using colorless oils to improve the luster of Emerald taken from Egypt. They people used to fill cracks in the Emerald with oil in order to pass light through the gemstone.
In the modern era, colorless cedarwood oil is used from the last 4 decades. It is not permanent, but better to use. Most of the emeralds sold by Embassy Emeralds have been lightly treated with cedarwood oil.
Gematrat was a way to permanently treat Emeralds. This was applied to leave them in a stable finished. This procedure is called ‘gemstone branding’ which begins with a very soft cleaning of the stone.
This procedure may take weeks or even months in some cases. The colorless Gematrat is used to fill the cracks in the Emerald.
Another Emerald treatment after Gematrat process is ExCel. This process is quite different from Gematrat because of any kind of treatment and the appearance of many fakes that mimicked the tracer’s effect under ultraviolet light.
