Dear,
I avoid selling emerald,ruby and sapphire because of inclusion problem.Most buyers dont understand.They want glass like clear stuff.In fact,I once experimented selling with bhatti amethyst and they sold like hot cakes.Disgusted,I stopped selling stones then.Indian buyers are most ignorant but they pose as wisest.
But sellers should not take advantage of ignorance of buyers.God will punish such sellers.
Thanx,
Truly,
Amitava
