The sculptured artefacts in the collection of the Da Nang Museum of Cham Sculpture are mainly of sandstone and terra cotta with a few bronze pieces. There is also a collection of clothing, photographs, films and digital discs.

 The sandstone sections are the most important and include pedestals, statues of gods, holy animals and symbols and architectural decorations from Cham temples and worshiping sites.

 The gods are identified with reference to the Indian mythology based on the holy animal the god often rode or the objects carried.

 The pieces are indetified according to where they were found or excavated, or the form or function of the object, including the round, relief, pedestal and architectural details. Thus criteria are explicit and uncontrovesial.

 Some researchers have used similarities, e.g. decorative design, the shape of hair curls, costumes, etc., to classify the Cham sculpture into several styles. Then, by referring to dates, which in some cases are clear enough, or to the styles in neighbouring countries, they have decided on the evolution of the styles. Each is named for the locality where a typical object of the style was found. For example, “the My Son E1 style” is applied to all objects bearing main features similar to those found in temple E1 at My Son in Quang Nam. The Dong Duong style refers to all objects similar to the sculptures from the Dong Duong relic in Quang Nam. The method of classification depends primarily on the conceptions and intepretation of different scholars.
