Mandana sandstone
Mandana sandstone run through our diamond polishing line — a flat, even, low-sheen face with the fine parallel tooling of the abrasive heads still visible in raking light.
Machine-polished on the diamond line
Diamond polishing is a machine process, not a hand one. The slab passes under a line of rotating heads carrying progressively finer diamond abrasive segments, each pass taking the surface down a grade until the face is dead flat and evenly reflective. What you are looking at on this page is exactly that surface, photographed in our own yard — no rendering, no sample board.
The characteristic of the finish is the tooling. Look across a diamond-polished slab in raking light and you will see fine parallel lines from the head travel, and on wider slabs the faint arc of the head path. That is not a defect. It is the honest signature of the process, and specifiers who want it want it precisely because it reads as worked stone rather than as a printed tile.
Because Mandana is silica-based rather than calcareous, it takes this treatment differently to a limestone. The polish does not close the surface into a mirror the way polished Kota does; it lands at a soft satin that keeps a little grip and hides marks far better than a full gloss. In practice that makes it a much more forgiving floor than people expect from the word ‘polished’.
We hold it in two commercial forms — random slabs straight off the bed run, and 22″ × 22″ cut squares. The random slabs are the economical option and the one to specify when the layout can absorb varied lengths. The 22″ square is the format most clients ask for by name.
Photographed at our yard at Amarpura. The faint parallel lines are the abrasive head travel — the signature of the diamond line.
The faint arc across the face is the path of the polishing head. On a large slab it is always visible in raking light.
Two commercial forms
Both come off the same beds and take the same polish. The choice is about how much your layout can absorb varied lengths — and what you are willing to pay for the convenience of a fixed module.
Straight off the bed run in whatever lengths the bed gives, sorted to consistent widths. Nothing is trimmed to a module, so nothing is wasted — which is why this is the most economical way to buy polished Mandana.
559 × 559 mm, cut square and edge-trimmed. The format clients ask for by name, because it lays as a straightforward grid with no setting-out arithmetic and no cutting on site beyond the perimeter.
Where it works
A polished face is a polished face. Indoors and under cover it is excellent. On an open terrace that takes monsoon rain and full sun it will dull faster than a honed or riven surface, and it is more slippery wet. For exposed exterior areas specify natural riven or grooved instead — we would rather tell you now.

Sizes
Square-foot figures are the finished face area, for converting a floor area into a piece count.
| Size | Metric | Sq ft / piece | Thickness | Notes |
|---|---|---|---|---|
| 22″ × 22″ | 559 × 559 mm | 3.36 | 18, 20, 25, 30 mm | The most requested cut square. General flooring |
| 24″ × 24″ | 610 × 610 mm | 4.00 | 20, 25, 30 mm | Standard 2′×2′ module |
| 22″ × 11″ | 559 × 279 mm | 1.68 | 18, 20, 25 mm | Half module, borders, treads |
| 18″ × 18″ | 457 × 457 mm | 2.25 | 18, 20, 25 mm | Smaller rooms, bathrooms, cladding |
| 12″ × 12″ | 305 × 305 mm | 1.00 | 15, 18, 20 mm | Cladding, dado, small areas |
| Random slabs | Bed-run lengths | By area | 20 – 40 mm | The economical option. Varied lengths, sorted widths |
| Cut to size | Any module on drawing | By drawing | 15 – 60 mm | Treads, risers, sills, copings, counters |
22″ × 22″ is 559 × 559 mm nominal. Cut-to-size work is held to ±1 mm on length and width; calibrated thickness to ±1 mm. See the full size and weight reference.
