Ibn Sirin
Emerald — Islamic interpretation
Dream interpretation
Seeing an emerald in a dream denotes martyrdom or the blessings that are created for a believer in paradise. If one buys' an emerald in a dream, it means that he will win a dear brother, associate himself with a group of righteous brothers on the path, raise well behaving children, acquire a useful knowledge, or earn lawful money.
These interpretations are reflective and cultural — not predictions, and not medical, psychological, financial, or other professional advice.
