The quiet stones,
and the hard ones.
Limestone gives you an even, low-noise floor — Kota Blue has been laid in Indian public buildings for decades because it takes traffic. Quartzite is the harder relative: dense, low-absorption and happy outdoors on facades and pool decks.
Limestone
Five limestones, from the blue-grey Kota that floors railway platforms and courtyards to the warm Jaisalmer yellows used across interiors and cladding.
Quartzite
Four quartzites, harder and less absorbent than limestone. Woodland is the one buyers ask for by name — the ring figure reads almost like sawn timber.
Choosing between the two
Same crate, different jobs — the decision is usually about traffic and weather.
Limestone is porous and reacts to acids, so it wants sealing in kitchens and a canopy in freeze-thaw climates. Quartzite takes weather better. For carved memorials, neither — that is granite's work.
Floor, facade or pool deck?
The answer changes the stone.
