Known as the May birthstone, most Emeralds mounted in Emerald Rings are immersed in oil to fill the cracks and fissures to which emeralds are prone, this is usually done both at the mine and at the cutters. Emerald oiling for Gold or Platinum Emerald Rings reduces the visibility of inclusions and improves the clarity of the stone. Sometimes green oil is used in addition to other more permanent fillers. Because oil filling of Emeralds has become almost universal, it is not considered essential to disclose this fact. Anyone wishing to buy a high quality or expensive Emerald should request a gemstone laboratory certificate stating that the stone is ‘natural' and not oiled, but be prepared to pay a great deal extra for such a stone.
