Precast stone is distinguished from precast concrete by the finer aggregate used in the mixture, so the result approaches the natural product. Overview ...
Cast stone or reconstructed stone is a highly refined building material, a form of precast concrete used as masonry intended to simulate natural-cut stone. It is used for architectural features: trim, or ornament; facing buildings or other structures; statuary; and for garden ornaments .
Stone is "natural precast concrete", so only needs to be cut (and strength tested) and post-tensioned prior to use in construction. Compared to concrete and steel, post-tensioned stone production has dramatically lower energy costs, with concomitant lower carbon emissions.

Some types of concrete used to make garden sculptures and planters have been called composition stone or composite stone. There is no single precise formula that differentiates composition stone from other lime-cemented concretes, which is unsurprising because the term predates modern chemical science, being attested since at latest the 1790s.
The precast concrete slab has tubular voids extending the full length of the slab, typically with a diameter equal to the 2/3–3/4 the thickness of the slab. This makes the slab much lighter than a massive solid concrete floor slab of equal thickness or strength. The reduced weight also lowers material and transportation costs.
