Treatment : color enhanced standard technique. Most emeralds are oiled as part of the post-lapidary process, in order to fill in surface-reaching cracks so that clarity and stability are improved.

Cedar oil, having a similar refractive index, is often used in this widely adopted practice. Other liquids, including synthetic oils and polymers with refractive indexes close to that of emeralds, such as opticon, are also used. These treatments are typically applied in a vacuum chamber under mild heat, to open the pores of the stone and allow the fracture-filling agent to be absorbed more effectively. (11) the use of oil is traditional and largely accepted by the gem trade, although oil treated emeralds are worth much less than un-treated emeralds of similar quality.

Other treatments, for example the use of green-tinted oil, are not acceptable in the trade. (12) gems are graded on a four-step scale; none, minor, moderate and highly enhanced.

These categories reflect levels of enhancement, not clarity. A gem graded none on the enhancement scale may still exhibit visible inclusions. Laboratories apply these criteria differently. The actual weight will be between the carat range mentioned, dimensions and weight are approximately mentioned, actual stone may slightly vary. You may return it within 15 days of receipt of same in original, unused and same condition. This item is made of emerald.
