Compare the exact piece

Product names can hide differences in mix, density, resin type, finish and intended use. Ask what the exact piece is made from, where it can be displayed and how the maker expects it to be cared for. A general material label is a starting point, not a guarantee.

Weight and stability

A lighter piece may suit a shelf, balcony or another position with a load limit. A heavier piece may be more stable, but weight also affects carrying, installation, the base and the surface below. Check the actual product information and wind exposure before placing it.

Weathering and finish

Outdoor performance depends on the exact material, finish, shape, drainage, shelter, wetness, salt, wind, sunlight and freezing exposure. Ask how the finish changes over time and whether a coating is allowed. Generic frost or UV thresholds do not decide whether a particular piece belongs in a particular garden.

Longevity evidence

Use product-specific evidence or documented examples, and keep the conditions attached to that evidence. A historic feature or a maker's example may provide context without predicting the life of another piece. Follow the exact product's placement and care instructions.

Price and replacement decisions

Compare the purchase price with the way you will use the piece, the cost of moving or securing it, available repairs and the maker's replacement or care guidance. A generic replacement calculation does not establish a lower lifetime cost for every material.

Environmental context

Both material classes have environmental costs. Compare the actual material, expected use, repair or replacement options and end-of-life guidance rather than turning a generic lifespan or price calculation into a sustainability promise.

If you are considering cast stone

Ask how the exact cast-stone piece was made, what its finish is, where it may be displayed and how it should be cleaned. Hand-casting or a workshop location does not by itself prove performance in every exposure.
