The product for this finish is generally made up of slaked lime, marble dust or marble chips. This accounts for its distinctive appearance. The ratio of lime to marble can vary depending on the provider or requirement of the client. Plaster can contain either lime, gypsum or cement. The final appearance of the finish is a glossy and lustrous finish that looks much like limestone, marble or travertine.

Venetian plaster is used as a wall and ceiling finish and consists of marble dust mixed with lime plaster in most cases. The mix is then applied in fine, even layers which are polished when fully dry until it becomes a surface with a glass like sheen.
When applied correctly, Venetian plaster produces a gleaming, rock-hard, marble like final product. Venetian plaster is commonly used to replace marble panels in cohesion with marbling in areas where such a product is difficult to install. Or on areas that would be highly costly to encompass real marble such as curved walls, pillars and columns and corniches.
Such plaster may be coloured, tinted or finished in varying ways modern technology has enabled. This is especially beneficial when unnaturally occurring colours are requested. https://en.wikipedia.org/wiki/Polished_plaster
