Persian Carrara White Marble gives many penthouse lobbies their quiet sense of glamour. This stone glows with a bright-white base crossed by fine grey lines that stay neat and calm. The pattern feels close to the famous Italian Carrara, yet it often looks even clearer because the ground is almost snow-white. Architects choose it when they need light to bounce around a room without glare. In the next sections, you will discover why this marble is a trusted choice for modern builders.
Of course, a beautiful surface only performs when its supply is steady and its quality is checked from quarry to crate. Buyers working on hotels or large housing blocks cannot risk colour shifts or late deliveries. They look for firms that control every stage, from cutting the bench to loading the container. One recognised name in this chain is JAM Stone Co. The company has run quarry and factory lines for a long time and now ships blocks, slabs, and tiles to more than forty countries. Their tight checks help designers specify Persian Carrara with real peace of mind.
Persian Carrara White Marble is a crystalline marble quarried mainly near the city of Qorveh in Iran’s Kurdistan Province. It formed when ancient limestone layers were squeezed and heated deep underground, turning soft rock into a strong mass of calcite crystals. The stone’s colour is a clear, cool white that carries thin pencil-grey veins. Because this look matches the original Carrara from Italy, many showrooms also label the Iranian variant “Carrara.” The material is sold worldwide in rough blocks, factory-cut slabs, and finished tiles.
Under the microscope, the marble shows a tight weave of tiny calcite crystals, each only about half a millimetre wide. This fine texture lets the surface take a deep, mirror-like polish that lasts. Tests place bulk density near 2.72 grams per cubic centimetre and open-space porosity under one percent, so water uptake stays low. The stone withstands 80 to 110 megapascals of pressure when dry, yet it can still be shaped with ordinary marble blades. These figures give designers strength, easy cutting, and stable colour in one package.
This marble is made of more than 95 percent pure calcite crystals. Fine flakes of dolomite and mica fill tiny spaces, while slim strings of quartz and graphite weave through some veins. The tight mineral mix gives a clean colour base and allows the surface to accept a deep, glass-like polish.
The ground colour is a cool, snow-white tone that holds light and spreads it gently. Thin pencil-grey lines under one millimetre wide cross the face in soft, random paths. When slabs are book-matched, these lines meet like mirrored feathers, making walls that feel balanced but never busy. The gentle contrast stays calm even in large spaces.
Laboratory tests give an average bulk density of about 2.72 grams per cubic centimetre, showing a tightly packed crystal network. Open-space porosity stays below one percent, and water absorption by weight is around a quarter of one percent. These figures mean the stone rejects liquid stains and resists freeze damage.
On the Mohs scale, the stone ranks between 3 and 4, the usual range for calcite marbles. It withstands 80 to 110 MPa of pressure in dry lab tests. However, wet testing shows a 5–10 % reduction in compressive strength, which is still adequate for interior flooring. Flexural resistance sits near 12–16 MPa, so floors take rolling loads without cracking.
Natural flaws are rare. A few hair-thin stylolite lines or micro-fissures may appear, but skilled workers flood them with clear epoxy before polishing. Clay seams and open pits larger than one millimetre are uncommon. Each slab is graded for background whiteness and vein activity, giving buyers a clear quality label.
Visually, the marble gives a clean white field that picks up light and spreads it softly through a room. On a polished face, the gloss meter often shows 85–92 GU on a 60° gloss meter, yet a honed surface will drop reflection while keeping the bright tone. Because the stone is mostly calcium carbonate, it reacts to acids, so owners should seal it and wipe lemon juice at once. Outdoor tests show tiny colour change under strong sun, and the very small pores lower the risk of frost damage. With normal care, the finish stays bright for many years.
When polished, Persian Carrara White Marble reaches gloss readings above ninety units at a sixty-degree angle, giving a sharp, mirror-like shine that brightens dim halls. A honed finish drops reflection to a soft glow without muting colour, while a leather finish adds fine texture that hides fingerprints and makes shower floors safer.
While all stone feels cool at room temperature, marble’s lower conductivity means it doesn’t draw heat from the skin as quickly as granite, a feature guests notice when they run a hand over a bar top. The extremely fine grain leaves a silky, almost waxy surface. Even brushed faces are comfortable under bare feet and easy to clean.
Accelerated weather tests show the marble keeps its colour, recording a ΔE change below one after 300 hours of strong ultraviolet light. Freeze-thaw cycles cause less than 0.5 percent mass loss because the pores are tiny. Owners should still avoid de-icing salts, which can dull the polish over time.
Like all calcite stones, Persian Carrara fizzes when it meets acid. Lemon juice, wine, or vinegar can leave a dull spot if not removed quickly. A modern silane-based penetrating sealer fills micro pores, buys time to wipe spills, and blocks oil stains for roughly two to three years before re-treatment.
Factories cut Persian Carrara White Marble into many shapes, so builders can match one source across an entire project. Most quarried blocks yield big slabs about three metres long and up to two metres high, either two or three centimetres thick. From these slabs, saws produce standard floor tiles, wall strips, stair treads, or custom inlay pieces cut by water-jet. Exterior pavers, bush-hammered or sand-blasted finish, are also offered at three centimetres. Mesh-back mosaics let installers lay small patterns quickly, keeping programmes on schedule.
Standard slabs cut from well-sized blocks run between 2.6 and 3.2 metres long and 1.5 to 1.9 metres high. Factories supply them in thicknesses of 20 or 30 millimetres. One slab gives roughly 5 square metres of coverage, making transport and layout easy for commercial builders, even on tight urban sites.
For floors and walls, workshops saw the slabs into popular module sizes such as 30 by 60, 60 by 60, and 40 by 80 centimetres. Each tile is gauged to within half a millimetre, so grout joints can remain narrow and neat. Thickness ranges from 10 to 20 millimetres depending on the load expected for stability in service.
CNC saws and water-jet tables shape bespoke panels up to 2 metres square for lift lobbies, stair treads, or furniture tops. Digital templates reduce waste because every curve follows the drawing exactly. Tight edges mean installers can slide each piece into place with almost no on-site trimming or grinding later.
Small chips, often twenty 23 millimetres square, are set on mesh sheets measuring 30 by 30 centimetres. Sheets bend slightly, so they wrap around columns or splashback corners without cracking. Installers can lay a full square metre in minutes, which speeds programmes, cuts labour cost, and preserves pattern accuracy greatly.
Where slip resistance is vital, factories blast and brush the surface to reach an R-eleven rating, then saw pavers measuring 40 by 80 centimetres at 30 millimetres thick. The rougher face scatters water, letting outdoor dining terraces stay safer during rain. Edges are eased to stop chips during handling daily.
To finish a room neatly, producers mill baseboards 100 millimetres high from 20 millimetre thick stock. The top edge is gently rounded, so dusting clothes glide over without catching. Matching skirting hides tile cuts and covers small floor movement gaps, giving the junction between wall and floor a crisp, tidy look.
Inside buildings, the marble is often seen on large lobby floors, calm bedroom walls, kitchen countertops, and vanity tops. The even veining lets designers create book-matched panels that look like mirrored wings. When brushed or leathered, the surface gains gentle grip, so many hotels specify it for shower floors or spa benches. Outside, the stone keeps its white tone under shade and light rain, so architects fit it to covered facades or veranda columns; Still, in polluted or acid-rain areas, periodic cleaning and repolishing may be required. Moreover, areas that see heavy traffic or strong acid, such as street paving or pool edges, need extra care.
Market price for Persian Carrara White Marble does not follow one fixed figure because several clear factors push it up or down. The first is colour grade. Pieces with a whiter background and few veins can cost twice as much as lower grades. Block size, added fabrication steps, finish, thickness, and transport distance all adjust the square-metre rate that reaches the site gate.
The background colour decides most of the price. Grade A shows over ninety percent pure white field with almost invisible veins, so buyers may pay twice the rate of Grade C. Because returns are fewer, contractors often save money overall by choosing the higher grade for visible areas in public.
Large, defect-free blocks let saws produce long, continuous slabs without cutting around flaws. More square metres leave the gang saw, so the stone cost per square metre falls. Smaller, cracked blocks take longer to align, waste more material, and force colour changes that slow installation on site significantly later downstream.
Polishing lines equipped with sixteen heads, resin vacuum tables, and calibrated thickness grinders turn raw sawn slabs into smooth, flat boards ready for tight joints. These extra passes add electricity, resin, and labour costs, raising the sale price by ten to fifteen percent compared with a basic, quick polish service.
A flat, high-gloss polish is normally the least expensive finish because the work stops once the surface reaches its glassy shine. Textured looks like leather, bush-hammer, or water-jet need new tooling and extra passes, boosting shop time and adding roughly ten percent to the delivered square-metre cost for clients overall.
Thicker pieces carry more stone and weigh more per square metre, so thirty-millimetre slabs often cost a quarter more than twenty-millimetre versions. Extra-long panels over three metres need wider crates and stronger lifting gear, and shipping firms add an oversize handling fee that passes to the buyer directly.
The quarry lies roughly six hundred kilometres from the nearest export port, so diesel prices and road tolls can swing costs by several percent each season. If space on container vessels becomes scarce, freight forwarders raise rates sharply. Delays tied to geopolitics or weather may also nudge prices upward further.
Extraction starts in Qorveh’s hillside benches, where diamond wire saws cut neat vertical slices into the white bed. After each block is freed, cranes lift it for trimming and a first resin patch that seals any hairline cracks. Trucks then cover the six-hundred-kilometre road to Tehran, where the block enters a multi-blade gang saw. Sixteen polishing heads create a glossy face, and the slabs cure for a day so the resin sets. After grading, workers slide foam sheets between pieces, strap them into wooden A-frames, and load containers that reach most ports within six weeks.
Routine care for this marble is simple but must be regular. At installation, the tile setter should spread a white, flexible cement adhesive, leave a two-millimetre joint, and fill it with fine epoxy grout that blocks stains. Once the surface dries, a penetrating sealer soaks in and guards against spills; owners should repeat this step every two to three years. Daily cleaning needs only a neutral-pH soap and warm water. Furniture legs need felt pads so metal does not scratch the polished skin. If light etching appeared on the surface, it could often be removed through progressive honing (400-, 800-, 1500-, and 3000-grit), followed by the application of a marble polishing powder.
JAM Stone Co. is a long-standing Supplier of Persian Carrara White Marble, controlling every step from the mountain face to the export crate. The firm operates its own quarry benches in Qorveh and a modern factory complex equipped with multi-wire saws, resin lines, and CNC cutters. This vertical setup allows close colour control because blocks, slabs, and tiles all move through one chain that uses digital shade mapping at each point. As a result, architects working on large hotels or housing projects can order repeat loads over many months without worrying about tone drift or delivery gaps.
Beyond production, the company has built efficient export routines. JAM Stone Co. is a trusted Exporter of Persian Carrara White Marble, holding ISO 9001 quality approval and the CE mark that opens doors to European worksites. Each batch leaves the plant with printed results for thickness, polish level, and absorption, so site engineers can file paperwork at once. Minimum order is usually one container, yet large projects benefit from just-in-time staging through Bandar Abbas port. A dedicated logistics team tracks vessel schedules and sends weekly updates, cutting the risk of costly site delays.
The Qorveh quarry holds an estimated reserve of more than one million tonnes, making the company a reliable provider of Persian Carrara White Marble for decades to come. Bench faces are planned with computer models that guide drills and limit waste. Water recycling keeps dust down and cuts fresh water use, while controlled blasting protects nearby ground. Regular core samples check crystal size and colour, ensuring that each bench matches earlier lots. With this predictable geology, the firm can guarantee long runs of consistent stone for phased projects.
Twenty-millimetre slabs travel in kiln-dried wooden A-frames lined with foam sheets, stretch film, and moisture barriers, while heavier thirty-millimetre pieces move in rigid, rubber-lined steel L-frames with forklift pockets for safe handling. Finished tiles sit in double-wall cartons cushioned by foam cells and secured on shrink-wrapped euro pallets. Every piece carries a barcode that links to batch data, and extra corner guards plus silica-gel bags cut breakage to 1–2 % under normal shipping conditions, ensuring projects receive intact, traceable stone even after long ocean journeys.
