What Chrono said... they are some sort of simulant. Synthetic would also be too expensive. Synthetic is emerald made in a lab. Simulant is something that looks like it. I think they look more like a jade simulant myself. And for the coup de grace... if the stones had been that clean, natural emeralds, those would have been cabbed and sold for about $200-1000 each.Chrono|1348100826|3271304 said:True, it could well be an emerald stimulant as well, which is more likely because that is less expensive.
