The big picture
The US quarries a meaningful amount of stone: about 2.3 million tons of dimension stone in 2025, from roughly 215 quarries in 34 states, led by Texas, Wisconsin, Vermont, Indiana and Georgia. Yet imports dominate consumption. The USGS estimates net import reliance at about 81% by value, with Brazil, Italy, China and India the leading sources.

Common US-quarried stones you'll see
| Stone | Where it comes from | Typical outdoor uses |
|---|---|---|
| Arizona flagstone (Coconino sandstone) | Ash Fork area, northern Arizona, the "Flagstone Capital" (AZ House Resolution 2001; quarry) | Patios, paths, wall cap, veneer |
| Pennsylvania bluestone | Only commercially produced in northeast Pennsylvania and south-central New York (NY DEC; Susquehanna County) | Treads, patios, coping, veneer |
| Indiana limestone | Salem Limestone belt, south-central Indiana; classified ASTM C568 Type II (Indiana Limestone Institute) | Caps, steps, cladding, sawn pavers |
| Tennessee "Crab Orchard" quartzitic sandstone | Crossville / Cumberland Plateau, TN (quarry) | Flagstone, coping, wall and veneer stone |
| California granite (e.g. Sierra White) | Raymond, Madera County, CA (Coldspring) | Steps, caps, architectural pieces |
A note on names: some trade names suggest a place they don't come from. "Three Rivers" flagstone, sold in California yards, was quarried in Idaho, and the supply is limited. Ask the yard for the quarry region of any named stone.
Common imports you'll see
| Stone | Typical origin | Typical outdoor uses |
|---|---|---|
| Travertine pavers and coping | Turkey (Denizli region), also Mexico and Italy | Pool decks, patios, coping |
| Sandstone and quartzite flagstone, sawn pavers | India | Patios, paths, steps |
| Limestone pavers and cladding | Portugal, Italy, France, Turkey | Modern patios, pool decks, cladding |
| Granite, basalt and setts | China, India, Brazil | Driveway setts, steps, caps |
| Slate and stacked-stone veneer panels | China, India, Brazil | Wall veneer, fireplaces |
These are the origins commonly marketed for these stones, not a census. USGS lists Brazil, Italy, China and India as the top import sources by value.
A fair comparison
| Factor | US-quarried | Imported |
|---|---|---|
| Selection | Narrower palette, strong in sandstones, bluestone, limestone, granite | Very wide: travertines, marbles, limestones, quartzites |
| Lead time | Often shorter for stocked items; custom cuts take time anywhere | Stocked items can be quick; special orders depend on production and ocean freight. Ask for a realistic date |
| Freight and carbon | Fewer miles, but long truck hauls still count | Ocean shipping is efficient per ton-mile; total distance and the truck legs add up |
| Price | Varies by stone and haul distance | Imported prices have been volatile; confirm current quotes |
| Matching future orders | Quarry is reachable; still lot-to-lot variation | Depends on the importer restocking the same quarry and lot |
| Testing | Ask for ASTM data | Ask for ASTM data |
On freight and footprint, the Natural Stone Institute notes that transportation is one of the most significant impacts of stone production, because stone is heavy, and its sustainability standard (ANSI/NSI 373) covers chain of custody and transportation management (NSI best practices). Closer is often lighter on carbon, but mode and route matter, so we don't treat any origin as automatically greener.
Quality and testing
Origin doesn't tell you whether a stone suits a pool deck or a driveway. Test data does. Ask for results to the ASTM specification for that stone type (for example C568 for limestone, C616 for sandstone and quartzite, C1527 for travertine), and slip data for wet areas. See why density and finish matter.
Questions to ask your yard or installer
- Which country and quarry region does this stone come from?
- Do you have current ASTM test data for this exact stone, and how recent is it?
- Is it in stock locally? If not, what's the realistic lead time?
- Can I reserve extra from the same lot for future repairs?
- If I need more in two years, will you likely carry the same stone?
- Does the quarry or supplier hold any third-party certification (such as ANSI/NSI 373), or publish its labor and sourcing practices?
- Is this price firm, and for how long?
Frequently asked questions
Is domestic stone better than imported stone?
Not inherently. Both include excellent and mediocre material. Judge the specific stone by its ASTM test data, finish, and suitability for your use, then weigh lead time, freight and how easily you can match it later.
How much natural stone used in the US is imported?
The US Geological Survey estimates net import reliance of about 81% of apparent dimension-stone consumption by value in 2025, with Brazil, Italy, China and India the leading sources (2021–24).
Are imported stone prices stable?
Imported prices have been volatile; confirm current quotes with your supplier before you commit.
