Silver Travertine is a natural limestone created when spring water rich in minerals left many thin layers of calcium carbonate that later hardened into rock. Quarries in north‑west Iran and western Turkey cut the stone along even beds that reveal calm silver‑grey bands and light taupe clouds. The cool neutral tone matches glass, steel, and pale timber, so architects choose it for modern houses, offices, and public spaces. Because the colour stays consistent between blocks, designers can continue the pattern across large walls and floors without visible breaks.
Over the last ten years, JAM Stone Co. has become a leading Supplier of Silver Travertine to architects in Europe, the Gulf region, and East Asia. The firm controls every stage from quarry face to export crate, so buyers receive uniform slabs, tiles, and cut‑to‑size pieces that align on site without extra grinding. Factory tests confirm water absorption around one percent and bulk density above 2.45 t per cubic metre, permitting thin façade panels that still pass wind‑load checks. Steady quarry output and reliable shipping timetables make JAM Stone Co. a partner contractors can plan around, even on tight programmes.
Silver Travertine is a mid- to light-silver-grey banded travertine member of the travertine family, a porous limestone deposited by warm or cold springs. Tiny iron oxides and organic pigments tint the stone a silver‑grey colour. When blocks are cut along the bedding, long ribbons appear; cross‑cutting produces cloudy swirls. Most surface pits are small and often filled with clear resin, so the face looks smooth yet natural. The mid‑tone shade links well with warm and cool finishes, allowing designers to use one material in both minimalist and classic projects.
Laboratory tests confirm the stone’s robust make‑up. Apparent density sits between 2 460 and 2 480 kg / m³, and water absorption ranges from 0.86 to 1.10 percent. With open porosity between six and thirteen percent, the stone is still light enough for easier handling. Compressive strength of at least 45 MPa and flexural strength near 12 MPa support cladding and paving. After 48 freeze‑thaw cycles mass loss is under one percent. When pores are vacuum‑filled with epoxy, water uptake drops below 0.9 percent and surface hardness increases.
The stone is made up of more than 90 percent micro‑crystalline calcite that precipitated layer by layer from spring water; minor dolomite and hematite particles give the silver tint, while back‑filled pores grow clear calcite that increases overall density yet keeps the attractive linear grain visible to designers and fabricators worldwide.
Parallel bands measuring between 1 and 10 millimetres run the full length of vein‑cut slabs, delivering a calm striped effect; when the block is cross‑cut the same layers break into cloudy swirls that look like storm clouds, giving contractors two distinct patterns that can be mixed yet remain tonally consistent.
Open porosity ranges from 6 to 13 percent, so the material breathes like classic travertine, yet factory vacuum filling drives residual water absorption 0.9 percent; that treatment, together with a bulk density above 2.45 tonnes per cubic metre, reduces frost risk and eases daily maintenance.
A Mohs hardness rating of 3 to 4 withstands routine foot traffic, while compressive strength exceeding forty‑five MPa and flexural strength around twelve MPa. It means even slender thirty‑millimetre façade panels can meet 4 kN/m² wind pressure when properly anchored, giving engineers solid data for code compliance calculations. Still, entrance mats are recommended to prevent grit scratching.
Industry grading allows no clay seams wider than one millimetre and limits visible iron spots to 5 percent of the face; every slab is resin‑filled and pass‑marked under strong back‑light to ensure there are no hidden cavities, so installers can polish edges on site without uncovering unexpected voids during final trimming.
Silver Travertine takes many finishes. A full polish reaches about 60 gloss units and gives a gentle metallic shine, while honed or brushed textures reduce glare and add warmth. The stone stays around 5 to 8 degrees Celsius cooler than concrete under summer sun, so it feels pleasant around pools. Outdoor colour fade is minor, and a fresh penetrating sealer each year keeps change around ΔE ≈ 1.8-2.2. Because the stone is rich in calcite, acidic liquids like vinegar can etch; neutral cleaners are safest for daily care.
When the surface is fully polished, the soft silver hues take on a gentle metallic sheen that pairs easily with brushed stainless steel and frosted glass; a honed finish tones the brightness down, delivering a calm matte effect for wellness areas, while brushed or tumbled textures highlight the natural grain without glare.
Factory filling smooths the surface, so honed tiles feel as soft as fine leather under bare feet, yet the micro‑pitting left by brush heads provides subtle grip. Some independent DIN 51130 tests on brushed samples verify an R 11 rating (project-specific testing is advised), giving pool designers confidence that the deck will remain safe even when children splash water everywhere.
After 48 accelerated freeze‑thaw cycles performed to ASTM C 666, mass loss remains under one percent and no spalling is recorded; annual outdoor testing also shows ultraviolet light causes a Delta E shift of less than two when an invisible penetrating sealer is renewed yearly, preserving the original silver tone.
Like all limestones, the high calcite content means acidic liquids will rapidly etch the surface. Tests with lemon juice show a dull spot forming within one minute, yet simple prevention is effective: a properly cured resin fill and a breathable impregnator create a buffer, and pH‑neutral cleaners avoid damage during daily housekeeping.
Stable bedding allows quarries to extract blocks up to 3 metres long, 1.8 m high, and 1.6 m deep. Saw mills then slice slabs between 2.5 and 3.2 m long and 1.3 to 1.6 m high in 20 or 30 millimetre thicknesses. Standard tiles measure 300 × 300, 300 × 600, 400 × 400, or 600 × 600 mm and are about twelve mm thick. For exteriors, pavers in thicknesses of 30 to 40 mm stand up to weather.
Standard slabs range from 2.5 to 3.2 metres in length and 1.3 to 1.6 metres in height, supplied in twenty or 30 millimetre thicknesses; book‑matching is available on request, enabling designers to create dramatic mirror patterns that run seamlessly across large feature walls and reception counters.
Stock tile formats include 300 by 300, 300 by 600, 400 by 400 and 600 by 600 millimetres, produced at a precise 12 millimetres thick and rectified to tight edges; modular sizing means installers can lay running bonds or chessboard layouts with grout joints kept to a neat two millimetres for easy maintenance.
Computer‑controlled water‑jet and bridge saw lines can craft facade panels, stair treads, or vanity tops up to two point two metres long to a tolerance of plus or minus 0.3 millimetres; digital dry‑layout photographs are provided before packing, letting architects approve vein flow and colour matching without visiting the factory.
Small tiles measuring 23 or 50 millimetres square are mounted on 305 by 305 millimetre mesh sheets; the brushed‑and‑filled finish keeps edges soft, making the sheets ideal for shower floors and curved feature walls where they wrap easily around radii without needing laborious individual setting by a tile setter during installation.
Outdoor modules are cut in French pattern sets of 6 by 12, 12 by 24, and 16 by 24 inches, usually at 30 or 40 millimetres thickness; the tumbled edges and sand‑blasted faces increase slip resistance, while the greater mass protects the stone from freeze cracking. It should also be noted that 40 mm pavers perform better on pedestrian patios; however, vehicular areas require thicker basaltic or granite units, or engineering approval.
Matching baseboards are produced at 100 millimetres height and 12 millimetres thickness with a softened top arris; using the same stone for skirting protects wall bases from cleaning equipment and rolling luggage, and it visually ties the floor plane to vertical surfaces without introducing another material or distracting colour change.
Quarry teams grade rough blocks as A, B, or commercial quality based on colour uniformity and structural soundness; A grade blocks longer than 2.8 metres are reserved for high‑end slab orders, while commercial grades may be sawn into smaller tiles, ensuring the best pieces go to applications where visual continuity is critical.
Designers use Silver Travertine for floors, walls, vanity tops, fireplace surrounds, and ventilated façades. Honed 20 mm tiles resist scratching in busy hotel lobbies. Brushed 30 mm pool copings stay comfortable for bare feet even in hot climates, while tumbled 40 mm pavers withstand freeze‑thaw cycles on patios and walkways. 30 mm façade panels anchored at 600 mm centres meet wind loads up to 4 kN/m². The stone’s calm colour also suits health spas and retail counters where a neutral background is wanted.
Factory prices for Silver Travertine start at about 8 US dollars per square foot for commercial‑grade tiles and rise to roughly ninety dollars for vein‑matched 30 mm book‑matched slabs. Outdoor pavers cost between 5 and 15 dollars per square foot, and French‑pattern sets are about 10% higher because of extra cutting. Price depends on stone grade, block size, finish, thickness, and extra steps such as resin filling or net backing. Freight often adds 15 to 25 percent, and temporary container shortages can raise costs further.
Premium A grade blocks show tight silver bands with no yellow spotting or clay seams, so slabs cut from them command 30 to 40 percent higher ex‑factory prices than commercial grade; owners often specify this grade for hotel reception walls where strong artificial light would highlight even the smallest colour clouding.
Larger blocks, especially those exceeding 2.8 metres in length, can be nested more efficiently on multi‑wire saw beds; higher yield means less waste per cubic metre quarried, which trims total cost by as much as 8 percent and also shortens production schedules for time‑critical architectural projects around the world.
Epoxy filling, net-backing, and final 400-grit polishing raise labour, resin, and diamond-tool costs. Each extra pass on the polishing line adds machine time and wear. Together these steps add about 1 to 3 dollars per ft² but also cut on-site breakage and deepen colour, a trade-off most buyers accept as good value.
Surface texture changes price. Polished slabs need finer abrasives and longer line time, adding roughly 2 dollars per ft². Brushed or tumbled pieces need extra passes yet hide pits, so they add only about 1 dollar. Honed-only or lightly brushed finishes incur the lowest processing cost; sand-blasting adds an extra texturing pass.
30-millimetre slabs cause more diamond wear and heavier freight, raising cost by about 30 percent over 20-millimetre stock. Jumbo panels above 3 m² need A-frame crates and special handling. By contrast, small modular tiles travel in cartons, so packaging and shipping stay cheaper even though the piece count is higher.
Freight moves with season and space. During the April-to-October quarry peak, back-haul discounts trim landed costs by 5 to 10 percent. Winter sailings or container shortages can push rates up 12 percent or more, and buyers may face four extra weeks of lead time while vessels and empties reposition.
Extraction begins with diamond wire saws set in stepped benches. Workers cushion the block on airbags before gently detaching it with chain saws. After resin reinforcement, the block travels by low‑bed truck to the factory where multi‑wire machines cut precise slabs. Ovens dry the stone, vacuum stations fill pores with epoxy, and polishers bring the required finish. A scanner records colour and dimension for quality control. Slabs are then bundled, wrapped, and strapped to A‑frames or placed into treated wooden crates that meet international rules. Door‑to‑door transit to most European ports averages six weeks.
Installers should use a white, polymer‑modified thin‑set mortar and double‑butter each piece to achieve at least 95 percent contact. Grout joints of 2 to 4 millimetres absorb natural size tolerance. A solvent‑based impregnator applied 72 hours after fixing and renewed every 12 to 18 months shields the surface from oils and moisture. Cleaning must be done with pH‑neutral detergents, because acids can etch calcite. Typical errors include mixing adhesive too wet, which reduces bond strength, and omitting edge sealing, which can cause darker lines along the perimeter of installed pieces.
JAM Stone Co. runs integrated quarries and processing plants that allow quick alignment between raw block qualities and project specifications. On‑site laboratories measure density, absorption, and colour before and after production, keeping thickness tolerance within half a percent and colour deviation below Delta E one. The company keeps more than 800 square metres of slabs ready for short‑notice orders, and CNC lines deliver complex shapes without outsourcing. This capacity, combined with transparent documentation, confirms JAM Stone Co. as a trusted Provider of Silver Travertine for both public and private ventures.
The firm’s logistics office schedules more than 400 containers per year to Europe, the Gulf, and East Asia. Buyers can order a single pallet or a full vessel load. Three inspections—at the block yard, after polishing, and during loading—check surface quality, flatness within 0.3 millimetres, and edge integrity. ISO 9001 and ISO 14001 certificates and CE marking support its records. Online photo reports and live tracking let contractors plan installation before the material arrives. Such consistent processes make JAM Stone Co a dependable Supplier of Silver Travertine on the global market.
The principal concessions sit in Isfahan and Markazi where gently dipping silver‑grey layers contain little clay. Wire‑saw cutting and controlled splitting recover blocks averaging 2.8 metres in length, increasing slab yield and reducing waste. Water recycling loops lower fresh consumption by 20 percent, and solar panels provide part of the plant’s power. Annual output above 6000 cubic metres secures continuous supply for large projects. By managing extraction and shipping under one roof, JAM Stone Co. acts as an efficient Exporter of Silver Travertine to demanding international clients.
Packing follows a strict routine that keeps breakage below one percent. Slabs are separated by two‑millimetre foam, strapped to steel‑reinforced A‑frames, wrapped in heat‑shrunk film, and fixed inside fumigated wooden crates that satisfy ISPM‑15 rules. Tiles and mosaics travel in labelled cartons placed in moisture‑barrier‑lined crates with corner protectors. QR codes link each package to factory records, and radio‑frequency tags update location data during transit. This documentation helps customs clearance and allows project managers to plan installation sequences before the container reaches site.
