Key takeaway
Granite is the more durable headstone material. It is made of hard silicate minerals (about 6 to 7 on the Mohs scale) that resist acid rain, so polish and lettering stay sharp. Marble is mostly calcite (about 3 to 4 on the Mohs scale), which acid rain slowly dissolves, so carved detail softens over decades. Marble can suit sheltered settings, but granite is the practical choice outdoors.
How do granite and marble compare?
| Factor | Granite | Marble |
|---|---|---|
| Main minerals | Quartz, feldspar and other silicates | Calcite (calcium carbonate) |
| Mohs hardness | About 6–7 | About 3–4 |
| Acid rain | Highly resistant | Dissolves slowly; surface roughens |
| Lettering over time | Stays crisp | Softens and can become hard to read |
| Colors | Gray, black, red, pink, blue, green and more | Mostly white or pale, some veined colors |
| Care | Water, soft brush, stone-safe cleaner | Gentler care; very sensitive to acids |
Why does marble weather faster than granite?
The U.S. Geological Survey explains that marble and limestone are made mostly of calcite, which dissolves easily in acid. Acid rain roughens the surface and removes carved detail, and in sheltered areas it can form black gypsum crusts. Granite is made of silicate minerals that are much more resistant to acid attack.
This is why old marble headstones in many cemeteries have faint, sugary lettering while granite stones of the same age are still easy to read.
Which material is harder and scratches less?
Granite. On the Mohs scale of mineral hardness, granite rates about 6 to 7, while marble rates about 3 to 4. Harder stone resists scratches and wear from weather, mowing equipment and cleaning, and it holds a high polish.
When might marble still make sense?
- Indoor or sheltered settings, such as a mausoleum.
- Matching an existing family marble monument.
- A traditional white look. The VA itself offers upright headstones in white marble as well as light gray granite.
Whatever you choose, confirm the cemetery allows the material. Some sections require granite or bronze. See our cemetery rules checklist.
How do you care for each material?
Both need only clean water, a soft brush and a stone-safe biological cleaner. Never use bleach, acids, wire brushes or a power washer. Marble is especially sensitive to acids, including many household cleaners. Follow the step-by-step method in our granite headstone cleaning guide.
What material are Memory Stones headstones?
Almost our entire in-stock catalog is granite, from upright headstones and shaped headstones to bench memorials and columbarium monuments. Each product page lists the material, color and size for that SKU, so always check the listing.
