Verified origin: Kuppam, Chittoor district, Andhra Pradesh. Also traded as: Koppam Green, KP Green.
Green is the one colour where Indian stone has a genuine, unforced advantage — and it is also the colour where buyers most often end up with a material they did not expect.
The material distinction that causes real problems
India exports two families of green stone, and they are not the same material:
Green granites — Kuppam Green (Kuppam, Chittoor, AP) and Hassan Green (Hassan district, Karnataka). Hard, durable, low-absorption, suitable for exterior and heavy-wear applications.
Green marbles — Forest Green (Kesariyaji / Rikhabdev, Udaipur), sold internationally as Verde Guatemala; Spider Green (Gogunda, Udaipur belt); and the Rainforest family (Bidasar, Churu). Softer, acid-sensitive, and in the Rainforest case serpentine and genuinely brittle.
They look related in a photograph and behave completely differently in a building.
A green marble specified where a green granite was intended will etch in a kitchen, weather differently in a churchyard, and require different handling in transit. A quotation that says only "green" is an incomplete quotation, and we write the material on every line for exactly this reason.
What Kuppam Green is
A deep, dark green granite — closer to bottle green than to olive — with a fine to medium crystalline structure and black mineral distributed through the green ground. Polished, it reads almost black-green in low light and resolves into green as the light comes up.
It is a hard, dense granite with the durability profile you would expect, which is what makes it usable where the green marbles are not.
Where it belongs
Monuments. The strongest use. Green is a settled preference in British and Irish memorial work, and Kuppam Green is the durable option. It weathers in a wet climate far better than a green marble will, which matters over the decades a memorial is expected to last. See Granite Headstones for the UK and Granite Headstones for Ireland.
Kitchen worktops. Dark, forgiving, distinctive. A green granite worktop is a confident choice rather than a safe one, and it sells to a specific client rather than to everyone.
Cladding and feature walls. Holds colour under UV, hides pollution staining.
Flooring in commercial interiors. Honed or polished.
External paving and steps. Flamed. Green granite flamed reads paler and greyer — show a physical sample before specifying.
Grading
Green depth and saturation. The main variable. Some blocks run darker and closer to black-green; some are lighter and more clearly green. Both are Kuppam Green. Only one of them is what your client saw.
Black mineral density. Heavier black content changes the read from "green" to "green and black speckle".
Consistency across a bundle. Green granites drift between benches. Approve a sealed physical range panel and reject against it.
Show it under the right light. Deep greens go black under warm light. If the stone is for a kitchen with warm under-cabinet LEDs, or a memorial in a shaded churchyard, look at it under those conditions before approving.
The other Indian greens, named properly
| Stone | Material | Verified origin | Note |
|---|---|---|---|
| Kuppam Green | Granite | Kuppam, Chittoor, AP | Koppam / KP Green |
| Hassan Green | Granite | Hassan district, Karnataka | Verde Hassan |
| Green Pearl | Granite | Guntur, AP | Reclassified in our records from North to South Indian — routes via Chennai, not Mundra |
| Apple Green | Granite | Jalore, Rajasthan | Verde Mela. Earlier records said Sirohi/Udaipur; field-corrected |
| Desert Green | Granite | Jalore, Rajasthan | Indian-trade name only |
| Nosra Green | Granite | Nosra village, Jalore | Indian-trade name only |
| French Green | Granite | Nosra village, Jalore, Rajasthan | Not French. Must be described as Indian. Our records resolve this as a North Indian stone. |
| Forest Green | Marble | Kesariyaji / Rikhabdev, Udaipur | Verde Guatemala — a well-established and legitimate alias |
| Spider Green | Marble | Gogunda, Udaipur belt | Verde Spider. Bidasar-family stone, processed in Udaipur |
| Rainforest Green | Marble | Bidasar, Churu | Serpentine, brittle, ships net-backed. Udaipur is processing only. See Rainforest Brown & Green Marble |
| Surf Green | Granite | Karimnagar / Prakasam | Earlier records said Hassan; field-corrected |
| Lime Green | Limestone | Jhalawar / Kota per field research — earlier records said Cuddapah, unreconciled | We quote this with the origin flagged |
Note "French Green". It is a Rajasthani granite from Nosra village in Jalore. It is not French, and describing it as such — or leaving the name to imply it — is the kind of thing that erodes a specifier's trust in everything else on your quotation. The same applies to French White, which is from Sivaganga / Madurai in Tamil Nadu.
Test data
Ask for the numbers for the quarry:
- ASTM C615 with C97, C170, C99, C880, C241/C1353 for US and Australian work
- EN 1926, EN 12372, EN 13755, EN 1936, EN 14157 for European work
- EN 12371 frost resistance if it is going outside in a freeze-thaw climate
- Slip data for the finish — wet PTV for the UK, DIN 51130 R-class for Germany, AS 4586 P-class for Australia
Logistics
Kuppam Green ships ex-Chennai or Krishnapatnam, being a South Indian stone. The Rajasthan greens — Apple Green, Desert Green, Nosra Green, French Green — ship ex-Mundra or Kandla. The Udaipur green marbles also ship ex-Mundra or Kandla.
If you are buying a green granite and a green marble together, that is two containers from two coasts. See North vs South Indian Granite.
What to ask a supplier
- Is this a granite or a marble? Ask it explicitly, every time, and get the answer on the invoice.
- Which quarry, and can it be held for repeat orders?
- Sealed range panel for green depth and black mineral density.
- Can I see it under the light it will live in?
- Frost and absorption data if it is going outside.
- For a memorial: can you match this in ten years?
What Gemarix does differently
We write the material on every line. Kuppam Green is a granite. Forest Green is a marble. Rainforest Green is a serpentine marble that ships net-backed and needs a handling clause. "Green" is not a specification and we do not quote it as one.
We also correct our own records in public — Apple Green is Jalore, not Sirohi; Surf Green is Karimnagar/Prakasam, not Hassan; Green Pearl is a South Indian stone that routes through Chennai. Where a record is unreconciled, such as Lime Green limestone, we say so.
Frequently Asked Questions
Where is Kuppam Green granite quarried?
At Kuppam in Chittoor district, Andhra Pradesh. It is also traded as Koppam Green and KP Green, and it ships from Chennai or Krishnapatnam rather than Mundra.
What is the difference between green granite and green marble?
A great deal. Kuppam Green and Hassan Green are granites: hard, low-absorption and suitable for exterior and heavy-wear use. Forest Green, Spider Green and the Rainforest family are marbles: softer, acid-sensitive, and in Rainforest's case serpentine and genuinely brittle.
Is Kuppam Green suitable for memorials?
Yes, and it is one of its strongest uses. Green is a settled preference in British and Irish memorial work, and a green granite weathers far better in a wet climate over decades than a green marble will.
Does Kuppam Green look black indoors?
It can. Deep greens go almost black under warm lighting and resolve into green as the light comes up. View it under the light it will live in, whether that is a kitchen with warm under-cabinet LEDs or a shaded churchyard.
Is French Green granite French?
No. French Green is quarried at Nosra village in Jalore, Rajasthan, and must be described as Indian. The same applies to French White, which comes from Sivaganga and Madurai in Tamil Nadu.
