It depends on the product. Some stone siding is genuine natural stone, quarried and cut for exterior use, while much of what’s used today is manufactured stone veneer, made from engineered materials designed to replicate the look of real stone.
Key differences between the two:
- Natural stone: authentic material, heavier, more expensive, and requires more structural support
- Manufactured stone veneer: lightweight, more affordable, and designed to closely mimic natural stone’s texture and color variation
Manufactured stone veneer has become the more common choice for most residential projects because it offers a similar appearance at a lower cost and with easier installation. High-quality manufactured products can be difficult to distinguish from real stone once installed.
If knowing the difference matters for your project, whether for budget, authenticity, or design reasons, ask your contractor directly which type of product they’re proposing before moving forward. They can also show you samples of both options for comparison.
