The transparency of this Colombian emerald is very good and two thirds of the crystal are pretty much inclusion free. Apart from oiling nothing has been applied to this stone! under the microscope you can spot the Muzo typical three-phase inclusions. A beautiful vivid green specimen with a discreet ”garden” !
