Jāmbūnada gold (The full and correct Sanskrit is Jāmbūnada. This is the name of a river in the Western Regions. The river is near Jāmbūnada trees, and the gold comes from within that river. Thus, the river was named after the tree, and the gold obtained its name from the river. Some also say that the sap of the jambu fruit turns things into gold when dropped on them, and flowing into the river, it stains the stones, forming this Jāmbūnada gold. Its color is reddish-yellow with purple flaming vapors).
