Abstract: The object of the invention is a rock product and a method for manufacturing the product in a mould. The product (1) according to the invention includes a nontransparent, opaque, preferably light reflecting, crystalline and granular rock material, the size of which granules corresponds mainly to the natural crystal size of the rock material in question as well as a mixture comprising a mainly synthetic resin and a mainly transparent filler. Thus, as the mixture (2) forms the transparent coating (4) of the product and binds the rock materials (3) into layers beneath the surface, rock product forms, as the substance hardens, which as such and without any working corresponds to the natural rock material with respect to its reflective properties and its impression of color and depth.
