NOTE: * This documentation accredits the emerald originating in Colombia (Colombian) and certifies that the gemstone shows moderate amount of oil in fissures; most emeralds undergo clarity enhancements with colourless substances such as oils or resins since they contain surface reaching fissures. 'Rather than regarding inclusions in coloured stones as harmful, in small sizes and numbers that do not in any way detract from their beauty, they should be regarded as adding to desirability, for they provide identifying characteristics.'
