The posted stone, emerald cut, 1.13 carats.This standard round brilliant was cut with its table parallel to the c axis and that produces alternate areas of the dichroic golden and green colors. This round appears to be eye clean and weighs .83 carats.
Older cut stone, round, .83 carats Same material.
I like a stone like this very bright emerald cut. It has a very good green c axis color and a more muted bronze a/b axis. The interplay of the green ends and bronze sides of the emerald cut makes for more interest in the stone than if they were mixed together. The gemstone appears to be eye clean and with fine crystal. It weighs 1.13 carats.
When I started faceting again after a long hiatus, I bought some rough, that was identical to the rough that produced this emerald cut. The dealer had sliced the nodules so the very good green axis dominated the color of the rough. I didn’t realized it at that time what he was up to and really how to deal with dichroic color, but I did question him. After not getting a very good answer, I cut the rough into rounds. They are OK, but this emerald cut shows the material has much more potential.
