Sukabumi Green Stone: Frequently Asked Questions

Sukabumi Green Stone is a natural andesite-based volcanic stone quarried in the Sukabumi Regency of West Java, Indonesia. Its distinctive grey-green colour comes from zeolite and chlorite minerals within the stone, and it is prized worldwide for swimming pool tiles, coping, pavers and cladding because it stays cool underfoot and resists slipping when wet.

It is quarried exclusively in the Sukabumi Regency of West Java, Indonesia, a volcanic region roughly 100km south of Jakarta. The specific mineral composition of this region’s andesite deposits is what produces the stone’s characteristic green-grey tone, which is why genuine Sukabumi Green Stone cannot be sourced elsewhere.

The green-grey hue comes from zeolite, chlorite and other secondary minerals that formed within the andesite as volcanic rock cooled and weathered over geological time. The intensity of the green varies slightly by quarry seam, which is why finish (natural cleft, honed, tumbled) and lighting both affect the perceived shade in photos.

No. Marble is a metamorphic rock formed from recrystallized limestone, while Sukabumi Green Stone is an igneous andesite — a volcanic rock. This matters practically: andesite is significantly harder and less porous than most marbles, which is part of why it performs better in wet, high-traffic pool environments.

Yes. Every piece is cut from quarried natural stone blocks — it is not a manufactured, cast or reconstituted product. Natural variation in colour, veining and texture between pieces is expected and is part of what distinguishes genuine natural stone from porcelain look-alikes.

Mineralogically it is composed primarily of plagioclase feldspar and pyroxene within an andesitic groundmass, with zeolite, chlorite and quartz present as secondary minerals that contribute to its green colouration and moderate porosity.

Yes. It is classified geologically as andesite, an igneous volcanic rock formed from cooled lava with a fine-to-medium grain structure, which gives it the density and hardness that make it suitable for high-traffic outdoor and pool applications.

"Bali stone" is a broad trade term covering several volcanic stone types quarried across Indonesia, including andesite and lava stone, and is often used generically in markets like Australia. Sukabumi Green Stone is a specific, single-source andesite from the Sukabumi Regency of West Java with a distinctive green-grey colour — not all "Bali stone" shares this origin or colour profile.

The name combines its origin (Sukabumi Regency, West Java) with its defining visual characteristic (its green-grey colour), making it immediately identifiable to international buyers searching for stone by both provenance and appearance.

No. Green quartzite is a metamorphic rock formed from sandstone under heat and pressure, typically quarried in regions like Brazil or India. Sukabumi Green Stone is a volcanic andesite from Indonesia — the two share a colour family but differ in geological origin, hardness profile and typical price point.

Three properties make it a preferred pool material: it stays notably cool underfoot even in direct tropical sun, its naturally textured cleft finish provides slip resistance on wet surfaces, and its low-to-moderate porosity combined with proper sealing resists algae growth better than many alternatives.

Yes, particularly in its natural cleft and bush-hammered finishes, which have a textured surface that provides meaningful traction when wet. For pool decks and coping, we recommend a DCOF (Dynamic Coefficient of Friction) rating check against your local pool-safety code, and can supply test documentation on request.

Yes — this is one of its most requested properties for tropical and desert climates. Its mineral composition and colour reflect more solar heat than darker stones like black lava, so pool decks remain comfortable for bare feet even after hours of direct sun exposure.

Yes. It is commonly used for waterline tiles because it resists staining from chlorinated and saltwater splash, holds its colour without fading, and its mosaic-format cuts allow it to follow curved pool edges cleanly.

Yes — pool coping is one of its most common applications. We supply bullnose (rounded edge) and square-edge coping profiles, both finished to provide a comfortable, non-abrasive surface for hands and feet at the pool edge.

Its moderate porosity resists algae better than highly porous stones, and algae resistance is further improved with a quality penetrating sealer applied at installation and reapplied per our maintenance schedule — unsealed stone in any material is more susceptible to organic growth.

Yes. Finished pool-grade Sukabumi Green Stone (natural cleft, honed or bush-hammered) is cut and edge-eased specifically for barefoot pool-deck use, avoiding the sharp arrises found on some cut stone products.

Yes. As a dense volcanic stone it is not chemically reactive to salt chlorination systems the way some cast concrete products can be, though we still recommend a quality sealer to protect against long-term mineral staining from splash-out.

It suits tropical, resort-modern, biophilic and natural swimming pool designs particularly well because of its organic texture and colour, though its clean-cut honed finish also works in contemporary minimalist pool architecture.

Yes — it is widely specified for infinity-edge pools in resort architecture, where its cool-touch and slip-resistant properties matter most at the exposed spillway edge, and its natural colour reads well against open sky and horizon views.

It sits in the mid-to-premium range for natural pool stone — more than basic ceramic or concrete pavers, generally comparable to or below premium travertine, and priced by size, finish and order volume. Container-load (wholesale) orders bring the effective per-square-metre cost down significantly versus small retail quantities.

Indicative pricing varies by finish, size and thickness; request a current quote referencing your target finish and order volume and our export team will return a firm FOB or CIF price within our published response SLA.

Per-ton pricing applies mainly to raw or semi-finished paver/coping orders sold by weight rather than area; contact our export team with your target product and finish for a current per-ton FOB quote.

You can buy direct from our factory in Sukabumi, West Java, as CV Alam Berkah Indonesia — this avoids the markup and quality-control gaps common with trading-company intermediaries. Submit a quote request and our export team will confirm pricing, MOQ and shipping to your country.

Yes — we are the factory. Buying factory-direct means no trading-company markup, direct quality-control accountability, and the ability to request custom sizes or finishes that a marketplace reseller typically cannot fulfil.

MOQ depends on product and finish; smaller sample and pilot-project quantities can be accommodated ahead of a full container order. Ask our export team for the current MOQ on your specific size/finish combination.

Yes. Finishes that require more processing labour (bush-hammered, flamed) generally cost more than natural cleft, and larger or custom-cut sizes carry a premium over standard stock dimensions due to lower yield per block.

Yes — we operate tiered wholesale pricing based on order volume, with the largest discounts applied at full-container quantities. Distributors and repeat-order partners can also discuss a standing distributor pricing agreement.

Standard export terms are typically a deposit against order confirmation with the balance due before or against shipping documents (T/T), with Incoterms (FOB/CIF) agreed per shipment; full terms are confirmed in your formal quotation.

That depends on the Incoterm quoted: FOB pricing covers cost to load the container at the Indonesian port of departure (you arrange onward freight), while CIF pricing includes freight and insurance to your destination port. We quote both on request.

The best supplier for your project is one that can show verifiable factory ownership (not just a trading listing), real third-party inspection certificates, named project references, and a clear, documented export process — criteria we publish openly across this site rather than asking buyers to take our word for it.

Verify factory ownership (ask for quarry/production photos and video, not just product shots), check for third-party inspection certificates such as SGS or Sucofindo, ask for named client references, and confirm they can produce a formal export process (Incoterms, documents, lead time) rather than a vague "we ship worldwide" claim.

Request their Indonesian business registration number (NIB), ask for a video call showing the actual factory floor, request third-party inspection documentation for a recent shipment, and ask for at least one verifiable named client reference in your region.

Sample policies vary by supplier; we offer paid samples with the cost creditable against a confirmed bulk order, which is standard practice for a heavy, freight-costly product like natural stone. Contact our export team for current sample terms.

Yes — as a factory-direct manufacturer we offer custom cutting to your specified dimensions and a choice of natural cleft, honed, tumbled, bush-hammered, sandblasted and flamed finishes, subject to minimum order quantities on non-standard sizes.

Yes — we currently export to 19+ countries across North America, Latin America, Europe, the Middle East, South and Southeast Asia, and Oceania, with documented shipping processes for each region.

Confirm the supplier’s factory legitimacy and certifications, request a technical data sheet (density, water absorption, compressive strength), clarify Incoterms and total landed cost, and check your own country’s import documentation requirements before placing a deposit.

Use our quote request form with your product, finish, approximate quantity and destination country, or message our export team directly on WhatsApp — we aim to respond within our published SLA of 24 business hours.

Yes, factory visits can be arranged by appointment for serious buyers — contact our export team in advance to schedule a visit to our Sukabumi, West Java production facility.

As a dense volcanic stone, properly installed and maintained Sukabumi Green Stone commonly lasts multiple decades in outdoor and pool applications, with periodic resealing being the main maintenance requirement rather than structural replacement.

Yes — it is used in tropical, desert and temperate outdoor climates worldwide. Its volcanic origin gives it good resistance to UV fading and thermal cycling, though extreme freeze-thaw climates should confirm frost-resistance specifications for their specific application.

It is highly colour-stable under UV exposure compared to dyed or resin-based alternatives, since its colour is intrinsic to the mineral composition rather than a surface coating. Minor natural weathering can slightly soften the tone over many years, which most buyers consider a desirable patina rather than a defect.

Water absorption is tested to ASTM C97 and figures are provided on our technical data sheet, which we recommend requesting for your specific finish and specification review — absorption varies slightly by finish and should be confirmed per batch for technical submittals.

Its dense andesite structure gives it reasonable frost tolerance compared to more porous stones, but for installations in climates with regular deep freeze-thaw cycling we recommend confirming frost-resistance test data against your local building code before specification.

As a dense andesitic volcanic stone, Sukabumi Green Stone falls within the typical bulk density range for quality andesite building stone; exact figures per batch are available on our technical data sheet on request.

Properly specified thicknesses for the intended application (pedestrian, vehicular, or structural cladding load) are engineered to resist cracking under normal use; compressive strength is tested to ASTM C170 and available on request for structural specification.

Yes — as an inert volcanic mineral it does not chemically react with standard pool chlorine or salt-chlorination systems, though we recommend a quality sealer to protect the surface from long-term mineral and chemical staining from splash-out.

Andesite typically rates around 6-7 on the Mohs hardness scale, making it substantially harder than most limestones and comparable to or harder than many granites used in exterior applications.

Yes, we recommend sealing with a breathable penetrating sealer at installation and on a periodic maintenance schedule — this reduces staining, water absorption and algae susceptibility without trapping moisture in the stone.

Installation follows standard natural stone tiling practice: substrate preparation, thin-set adhesive application, tile/paver setting with appropriate grout spacing, grouting, and finally sealing — our full installation guide walks through each step in detail.

A polymer-modified thin-set adhesive rated for natural stone and exterior/wet-area use is recommended; avoid standard ceramic-only adhesives, which can fail to bond adequately with denser natural stone in submerged pool applications.

Yes — concrete is the most common substrate for pool decks, coping and paving applications, provided the slab is properly cured, cleaned and, where needed, primed before adhesive application.

We strongly recommend an installer experienced with natural stone, particularly for pool applications where correct slope, waterproofing and grout spacing are critical to long-term performance — our installation guide can also be shared with your chosen contractor.

Grout spacing is typically specified between 3-10mm depending on tile format and the natural edge variation of the finish chosen (natural cleft edges generally need wider joints than precision-cut honed tiles) — full guidance is in our installation guide.

Yes — cladding panels and veneer-format cuts are specifically produced for vertical wall and facade applications, using mechanical fixing or adhesive systems rated for the panel weight and substrate.

Timeline depends on project size and installer crew size; a typical residential pool deck/coping installation runs from a few days to two weeks including substrate prep, curing time, grouting and sealing.

A wet tile saw with a diamond blade rated for natural stone is required for on-site cuts; for large-format or specialty cuts we recommend having factory pre-cut sizing done to your specification rather than field-cutting.

Routine cleaning with a pH-neutral stone cleaner and soft brush is sufficient for most maintenance; avoid acidic cleaners (including undiluted vinegar or citrus-based products), which can etch the stone surface over time.

Yes, with care — use a moderate pressure setting and a wide fan nozzle held at a safe distance, since excessive pressure at close range can erode grout lines and, over repeated use, the stone surface itself.

A typical resealing interval is every 1-2 years for pool and high-exposure outdoor applications, though this varies with sealer quality, climate and traffic — our maintenance guide includes a simple water-bead test to check when resealing is due.

Algae buildup is typically caused by unsealed or under-sealed stone combined with persistent moisture and shade — regular cleaning and a properly maintained sealer coat are the most effective preventive measures.

Yes, in most cases — surface staining and light etching can typically be restored with professional stone honing/polishing, while individual cracked or chipped pieces can be replaced without disturbing the surrounding installation if spare stock was retained.

Use pH-neutral, stone-safe cleaning products specifically labelled for natural stone. Avoid bleach, ammonia-based glass cleaners, and any acidic household cleaner, all of which can degrade the sealer and etch the stone surface over repeated use.

Properly sealed Sukabumi Green Stone resists most common staining sources (suntan oil, food, mineral splash) reasonably well; unsealed stone is considerably more susceptible, which is why we recommend sealing at installation regardless of application.

Use a stone-safe calcium/lime remover formulated for natural stone (never a generic acidic descaler), applied per the product’s instructions and tested on an inconspicuous area first — our maintenance guide covers the full recommended process.

Stone is cut and finished to order, quality-inspected, packed on pallets or in crates suited to the product format, and loaded into 20ft or 40ft ocean freight containers for shipment from an Indonesian port to your destination port under agreed Incoterms.

Ocean freight transit typically runs 5-8 weeks door-to-port depending on destination coast and routing, plus local customs clearance time — see our USA country page for more specific port and lead-time guidance.

Tiles and pavers are typically palletized and shrink-wrapped or crated with corner protection to prevent chipping and moisture damage in transit, with packing optimized to maximize safe container loading per square metre.

Typical documentation includes a commercial invoice, packing list, bill of lading, and Certificate of Origin (Form A) — exact requirements vary by destination country, and we prepare the full document set for each shipment.

We handle export clearance from Indonesia; import-side customs clearance in your destination country is typically arranged by your appointed customs broker, though we provide full, accurate documentation to support a smooth clearance process.

FOB (Free on Board) pricing covers the cost of goods loaded onto the vessel at the Indonesian port of departure, excluding onward freight and insurance — request a current FOB quote referencing your product, finish and quantity.

Small sample or pilot-project quantities can be shipped via consolidated LCL (less-than-container-load) freight, though full-container (FCL) orders offer significantly better per-unit shipping economics for larger projects.

We commonly quote FOB (Free on Board) and CIF (Cost, Insurance and Freight); other Incoterms such as EXW or DAP can be arranged on request — our export process guide explains the practical difference between each.

Container yield depends on product format, thickness and packing method; our export team can provide an exact square-metre-per-container estimate for your specific product and finish selection to help plan order volume.

Both are excellent pool materials with different strengths: Sukabumi Green Stone generally offers cooler underfoot temperatures and a distinctive green tone, while travertine offers a warmer, classic Mediterranean aesthetic. Choice usually comes down to design intent, climate and budget — see our full comparison for a side-by-side breakdown.

"Bali Green Stone" is often used as a generic trade name for various green-toned Indonesian volcanic stones, while Sukabumi Green Stone refers specifically to material quarried in the Sukabumi Regency of West Java — buyers should always confirm actual quarry origin rather than relying on trade branding alone.

Porcelain offers highly consistent colour and lower maintenance, but Sukabumi Green Stone offers natural texture, superior cool-touch performance in direct sun, and an authentic material story that porcelain cannot replicate — many resort and luxury projects specify natural stone specifically for that authenticity.

Pebble Tec is an aggregate pool-finish system applied to the pool shell itself, while Sukabumi Green Stone is a cut natural stone tile/coping product — they typically aren’t direct substitutes but are sometimes combined (Pebble Tec interior finish with Sukabumi Green Stone coping and deck).

Sukabumi Green Stone (andesite) is generally denser and less porous than most limestones, giving it better resistance to acid etching from pool chemicals and better long-term durability in wet environments, though limestone offers a lighter, more neutral colour palette some designers prefer.

Both are Indonesian volcanic stones, but black lava stone is notably darker and absorbs significantly more heat in direct sun, making it less comfortable for bare feet on pool decks compared to the cooler-toned Sukabumi Green Stone.

Natural stone is a long-lasting, low-processing-energy building material compared to many manufactured alternatives, and responsible quarrying practices — which we follow — further reduce environmental impact; ask our team for specifics on our quarry management practices.
