This medium light toned emerald cut slides around between green and bluer green depending on the light. It has excellent transparency except for a few marks scattered in the stone. The most important is on a corner of the table and is noticeable to me. There is no darkness in the ends because the stone is not dichroic to any extent. The bicolor nature of the stone is from more a change in tone, only one step I would say, rather than anything discernible in color. The gradation goes from one end of the emerald cut to the other. This interesting stone weighs 7.05 carats.
