Basaltina Lava Stone
Honed
Basaltina is a volcanic tuff quarried in the hills near Viterbo, north of Rome — the same stone Michelangelo used for the paving of the Piazza del Campidoglio in 1536. Naturally warm charcoal-grey, extraordinarily dense, and resistant to freeze-thaw cycles. A quiet, contemporary alternative to bluestone.

Care & maintenance
How this floor ages well.
- 01Seal on install and refresh sealer every 12–24 months for high-traffic areas.
- 02Sweep or vacuum daily; damp-mop with a pH-neutral stone cleaner weekly.
- 03Never use vinegar, lemon, bleach or ammonia — all etch calcareous stones (limestone, marble, travertine).
- 04Wipe wine, citrus, oil and coffee within seconds to prevent etching.
- 05Have honed finishes re-honed by a stone-restoration professional every 10–15 years to remove wear scratches.
