Donji Humac is surrounded by a number of quarries. The local stone has given the settlement its distinct look very early on, and many of the old elements of the settlement are still preserved. The closeness to the quarries had also led to a tradition of artistic stonemasons in the village, which is carried on until present. In 1996, an international meeting of stonemasons lead to the creation of a number of monuments which are now spread throughout the settlement. Besides stone, the main sources of income have traditionally been wine, olives, cherries, and hunting, and more recently, tourism.
