CEDAR WOOD OIL
Natural colorless Cedar Wood oil has been added to emeralds since the 1960's. This is the traditional way to process emeralds and has been done to almost every stone that has come out of all the mines around the world. Cedar wood oil can come out of the stone if heated too much but lightly enhanced ones rarely change.

PALM RESIN
Colombia began to produce a resin designated as "Palma" after many of the Cedar Wood stones lost their oil during the flight to North America or the Orient. They decided to make a special plastic like Opticon which would fill the inclusions and stay in the stone. Unfortunately, Palma turns a milky white substance after just a few months. The large conglomerate Japanese buyers in Bogota in 1993-1994 decided to make a policy not to ever accept Palm oil from any supplier. The Emerald Congress '98 in Bogota also agreed to rule Palma as an unacceptable filler. Still, palma resin is very prevalent again this year and buyers must be careful to avoid this treatment.
