Premium granite varieties and premium quartz both push these figures up substantially; the ratio between them stays roughly similar.
Design and build under one accountable roof
The heat question, which is the one that matters
In most Indian kitchens a vessel comes off the flame and goes somewhere. If that somewhere is the counter, granite is the correct material and no amount of explaining will change the household’s habit.
- Quartz resin discolours above roughly 150°C, leaving a dull grey ring that cannot be polished out. It is not a warranty defect; it is the material behaving as designed.
- A trivet solves it entirely, and a household that will genuinely use one loses nothing by choosing quartz.
- Be honest about this before specifying. We ask the question directly at the design meeting, and the answer decides the material more often than the budget does.
- A practical compromise: quartz counter with a granite or stainless landing strip beside the hob. It costs a little more in fabrication and removes the risk entirely.
- The reverse risk — staining granite with turmeric — is solved by sealing, which requires someone to remember every two years.
When granite is genuinely the better choice
- Households where hot vessels go straight onto the counter. Stated plainly, this is most Indian kitchens.
- Budgets where the ₹25,000–50,000 saved buys better hardware or a better carcass.
- Dark stone schemes, where Absolute Black or Black Galaxy hides everything and needs almost no sealing.
- Outdoor and balcony counters, where quartz’s binder would amber in UV.
- Clients who actively want natural stone with variation, rather than a manufactured surface.
When quartz is worth the premium
- Light-coloured counters. A white or pale grey quartz will look the same in year ten; a pale granite will not without disciplined sealing.
- Households with domestic staff doing the cooking, where the sealing regime is unlikely to be maintained by anyone.
- Kitchens where the counter is a visual feature — an island in an open-plan living room — and consistency of pattern matters.
- Anyone who has previously had a granite counter stain and does not want to repeat it.
- Bathroom vanities, where quartz’s non-porosity is an advantage and heat is a non-issue.
Fabrication, which is where both materials are actually won or lost
The slab is a factory product in the case of quartz and a quarried product in the case of granite. The countertop, however, is a hand-made object, cut by a fabricator in a yard in Kurla or Bhiwandi, and most counter failures trace back to that stage rather than to the material.
- Radiused internal corners at the sink and hob cut-outs. Square internal corners concentrate stress and are where almost every counter crack starts, in either material.
- The carcass tops must be level within 2 mm across the run. A slab laid on an uneven carcass is under permanent stress.
- Template after the units are installed, not from the design drawing. Mumbai walls are rarely plumb and a 10 mm error becomes a visible wedge of silicone.
- Steel flat support under any overhang beyond 250 mm, on a breakfast bar or an island.
- Agree the seam position on a drawing before cutting. One seam per 10 feet of run is unavoidable; where it lands is a choice.
Verdict by household
| Household | Our recommendation |
|---|---|
| Cooks Indian food daily, vessels off flame to counter | Granite, dark variety |
| Cooks daily, will use trivets | Quartz, with a stainless landing strip by the hob |
| Light-coloured kitchen scheme | Quartz — pale granite will stain |
| Open island counter, visual feature | Quartz for pattern consistency |
| Budget under ₹30,000 for the counter | Granite — quartz is not reachable at that figure |
| Balcony or outdoor counter | Granite — quartz ambers in UV |
What we specify most often in Mumbai: quartz on the main counter, with a granite or stainless insert beside the hob for hot vessels, and granite in the utility. It costs a little more than either alone and it removes both failure modes.

Frequently asked questions
Does quartz really never need sealing?+
Correct — the quartz grains are bound in resin with no interconnected pores, so there is nothing for a sealer to penetrate. If a quotation includes annual quartz sealing, it has been copied from a granite specification.
Will turmeric stain granite?+
Light, granular varieties, yes, if they are unsealed. Dark dense stone such as Absolute Black rarely shows anything. A penetrating sealer applied at handover and re-applied every 18–30 months makes staining a non-issue on any variety.
Can I put a hot pan on quartz for a few seconds?+
You may get away with it, and you may not. The damage is a permanent dull mark, so it is not worth testing. Keep a trivet, or specify a granite or stainless landing strip beside the hob, which is the detail we use most often.
Which looks better?+
A matter of taste, but the honest observation is that quartz gives you consistency and granite gives you character. A veined quartz in a photograph is indistinguishable from marble; a Black Galaxy granite has a depth no manufactured surface reproduces.
Which is easier to live with over ten years?+
Quartz, marginally, because it needs nothing. Granite needs a sealer every couple of years, which is a twenty-minute job that most households forget. If you will remember, granite is the more forgiving surface in every other respect.
