Ivory Onyx, a rare calcite stone sourced from Iranian quarries, is usually the reason behind the soft glow seen when stepping into a boutique hotel lobby after sunset and noticing how the walls seem to shine from inside. Thin slabs turn translucent when lit, so their pale cream bands look like ripples of warm water. Because the stone is dense and almost pore‑free, polish reaches a mirror sheen and colour stays calm under daylight and LEDs alike. Designers choose it when they need luxury surfaces that feel bright yet natural.
Before moving on to our main topic, it seems vital to bring up the name of a reliable supplier of this onyx type. JAM Stone Co. has spent two decades turning quarry blocks into ready‑to‑install panels. As a trusted supplier of ivory onyx, the company controls every step, from block selection in Semnan to vacuum resin treatment and final packing at its Isfahan plant. Integrated checkpoints keep slab yield high and defects low, so architects get uniform colour and light flow. Dedicated export staff prepare CE paperwork and load shock‑protected crates, cutting breakage to under one percent. Global projects in Europe, the Gulf, and East Asia rely on this consistent pipeline.
Ivory onyx, also known as Avorio onyx, forms deep inside warm, mineral‑rich caves where calcium‑laden water deposits layer after layer of crystalline carbonate. Over thousands of years, these layers harden into dense bands that range from ivory white to light caramel. Because the crystal network is so tight, twenty‑millimetre slabs pass light almost like frosted glass. The stone’s gentle palette and translucency make it a favourite for back‑lit walls, reception counters, and spa features that must feel both calm and exclusive.
Ivory onyx may look delicate, yet its structure offers surprising strength for vertical uses. Uniform calcite bands keep flexural values predictable, while vacuum resin and mesh backing add safety margins. Micro‑pores stay under one percent, so only a light sealant layer is needed before polishing. Architects, therefore, gain a material that is visually striking, structurally trustworthy, and easy to process on standard marble lines.
Composed of more than 95 percent calcite with traces of aragonite and iron oxides, ivory onyx owes its warm ivory and honey tones to these microscopic mineral inclusions. Fine crystals, smaller than half a millimetre, allow controlled light passage, giving designers a naturally diffused glow without harsh hotspots.
The stone’s calm ivory base carries straight bands one to ten millimetres wide in honey, light grey, or soft caramel. Bands run parallel, so book‑matched slabs create near‑mirror images that stretch across entire walls, offering rhythm without chaotic blotches or abrupt colour shifts.
Bulk density sits near 2.60 tonnes per cubic metre, while open pores seldom exceed one percent. Water absorption tests stay between 0.6 to 1.3 percent, meaning only micro‑pinholes need resin before polishing, and standard light‑duty adhesives work without later yellowing.
On the Mohs scale, ivory onyx measures about three, softer than granite, yet still posting compressive strengths, ranging from 70 to 85 MPa. Resin treatment and mesh backing raise flexural capacity, so twenty‑millimetre panels withstand handling stresses during fabrication and site installation.
Grade‑A blocks exhibit fewer than three hairline cracks per square metre. Tiny quartz seams stay under half a millimetre and are sealed with clear epoxy. Multiple light inspections ensure the final surface shows no dark knots, heavy fill, or open voids.
Before diving into technical numbers, it helps to know why this grade of Iranian onyx captures attention. When lit from behind, the stone glows like alabaster, yet keeps distinctive linear stripes, giving spaces both warmth and order. Surface finishes range from high gloss to velvet‑like leather, so designers can match the stone’s mood to any lighting and foot‑traffic level.
Back‑lighting a twenty‑millimetre slab produces a gentle amber glow; polished faces record high gloss values, letting mirrors, elevator cabs, and signage panels stay bright even where ambient light is low.
Sixteen‑head polishing leaves a glassy face that still feels warm because calcite transmits heat slowly. Leather or honed textures lower glare and add subtle grip, making spa walls safe while keeping the linear pattern vivid.
Indoors, colour shift stays under 1.5 delta‑E after five years. Outdoors, freeze–thaw cycles can widen micro‑fissures, and strong UV gradually dulls the polish; therefore exterior use needs sheltered locations. Moreover, it requires a frost-free setting or routine sealing/re-polish programme.
More than 95 percent calcium carbonate means any acid—lemon juice, vinegar, even some cleaning sprays—can visibly etch within a minute if the surface lacks sealer. A yearly penetrating sealer raises contact angle and buys time for quick wipe‑ups.
Because demand spans everything from grand hotel lobbies to small boutique spas, JAM Stone Co. offers ivory onyx in a flexible range of dimensions. Sawing, CNC shaping, and mosaic assembly all happen in‑house, so matching pieces arrive on site numbered and ready for layout, reducing waste and guesswork during tight project schedules.
Gang‑sawn slabs measure 2.4 to 2.6 metres long and up to two metres wide at twenty or thirty millimetres. Resin impregnation, mesh backing, and calibration to within eight‑tenths of a millimetre keep installation smooth and predictable.
Standard formats are 600 by 600 by 20 millimetres and 300 by 600 by 12 millimetres. All edges are micro‑bevelled for two‑millimetre joints and offered in polished, honed, or leathered finishes to match adjacent slabs.
CNC and water‑jet cutters shape curved bar fronts, reception desks, and signage down to fifteen‑millimetre thickness. Digital nesting aligns stripes across joins, creating seamless flows on complex geometries.
48 millimetre squares, hexagons, or herringbone strips are mesh‑mounted on 300 millimetre sheets at 10 millimetres thick. Honed faces give wet zones a soft grip while letting light tickle each tessera.
Skirting boards range from 100 to 150 millimetres high and up to 1.2 metres long. A delicate bevel on the top edge prevents dust build‑up and eases maintenance.
Ivory Onyx excels where lighting and ambience work together. Back‑lit lobby walls, spa counters, and luxury store displays use twenty‑millimetre polished panels to transform plain partitions into glowing focal points. Vanity tops, shower walls, and cinema stair inserts favour honed finishes that soften reflected glare while preserving the stone’s inviting warmth. Designers also insert thin accent strips in lift portals and ceiling coffers to draw the eye through long corridors without overwhelming other finishes.
While ivory onyx is rarer than most marbles, its cost varies widely with grade, block size, and finishing choices. Understanding each driver helps buyers set realistic budgets and avoid costly surprises during later fabrication and installation stages.
Blocks with uniform colour, high translucency, and minimal fissures command premiums up to thirty percent above standard inventory; many owners pre‑book such blocks early to guarantee supply.
Large blocks over 2.5 metres reduce cutting waste and improve nesting, so their higher purchase price often lowers the final square‑metre cost once fabrication is complete.
Multi‑wire sawing, full‑vacuum resin, and sixteen‑head polishing add roughly fifteen dollars per square metre, yet prevent later repairs and minimise on‑site breakage rates.
Polished and book‑matched faces require extra labour and precise layout, pushing prices higher, whereas honed or leathered surfaces typically cost eight percent less.
Thirty‑millimetre slabs or intricate water‑jet components use more material and machining time, raising costs by about twenty percent versus standard twenty‑millimetre pieces.
Limited quarry output and long sea routes push typical FOB Bandar Abbas values to 120 through 160 dollars per square metre, with seasonal surcharges during peak shipping months.
Ivory onyx begins its journey in Semnan’s arid hills, where diamond‑wire saws cut neat benches into the pale carbonate bed. After controlled wedge blasting, loaders gently tilt blocks onto rubber‑sheathed cushions to avoid impact bruises. Technicians then map colour bands with laser lines and grade each block for translucency, fissure count, and size efficiency. The best pieces—usually about forty percent of daily output—are wrapped in damp jute for slow moisture equalisation and tagged with QR codes that track them through every downstream step. Blocks travel on cushioned low‑bed trailers to the Isfahan processing plant overnight to beat daytime heat.
At the factory, each block enters a vacuum chamber where warm epoxy resin fills micro‑fissures and boosts light transmission. Multi‑wire saws slice the block into calibrated twenty‑ or thirty‑millimetre slabs, which then pass under sixteen‑head polishers that lift surface gloss beyond ninety units. Digital callipers verify thickness, while handheld spectrometers record colour coordinates for batch consistency. After final QC, workers laminate a fibreglass mesh to the back, wrap faces in moisture‑barrier film, and slot slabs into foam‑lined A‑frames. GPS‑tagged containers leave Bandar Abbas weekly, reaching Gulf, European, or East Asian ports within four to six weeks.
Ivory Onyx installs best with high‑strength white rapid‑set tile adhesive that carries a low‑alkali formulation to prevent colour shadowing through the translucent body. Spread adhesive across the full back in straight‑line trowel ridges and press the slab firmly until no voids remain. Keep grout joints narrow—two millimetres for calibrated tiles, three for field‑cut panels—and fill them with a non‑sand, flexible epoxy grout tinted to match the light cream tone. Finish by applying a breathable penetrating sealer immediately after grout cure and repeat every twelve months in dry zones or every six months in wet rooms.
Routine cleaning should rely on pH‑neutral stone soap and soft microfiber cloths; abrasive pads abrade the mirror polish, while acidic sprays etch within seconds. Always place felt pads under furniture and use doormats to trap grit that could scratch the surface. During installation avoid grey cement mortars because dark pigment telegraphs through thin back‑lit panels. Never expose the stone to strong alkaline builders’ cleaners or steam mops that drive moisture into micro‑fissures. When minor etching or scratches appear, re‑polish with a fine calcite powder slurry and reseal the affected area immediately.
JAM Stone Co. controls every link in the Ivory Onyx chain, from raw‑block selection to finished slab export. Decades‑long partnerships with respected mine owners in Semnan and Yazd guarantee steady access to premium beds. Inside the Isfahan factory, multi‑wire saws, CNC water‑jet cutters, and precision polishers work beside in‑house quality labs that verify colour uniformity, thickness, and gloss. Integrated operations mean each batch moves under one management system, giving architects consistent grading, tight tolerances, and on‑schedule deliveries without middle‑layer delays.
As a global supplier of ivory onyx, the company secures buyer confidence through multi‑stage inspections that check visual grade, surface flatness, and edge integrity at every step. ISO 9001 and CE certifications back these routines, while magnetic thickness gauges and gloss meters record each lot in a digital logbook. A proven export record covers GCC megaprojects, European retail chains, and East Asian spa resorts. Minimum order quantities flex from a single crate to full‑vessel loads, and client‑specific cutting or nesting plans ship worldwide in moisture‑sealed crates that reach site on time.
JAM Stone Co. has built a powerful partnership with an exclusive Ivory Onyx quarry, which sits on Semnan’s third carbonate bed, prized for its calm ivory field and evenly spaced honey bands. This relationship ensures uninterrupted sourcing and strict bench‑by‑bench colour mapping, so large commercial volumes match perfectly across seasons. Core samples show massive reserves with less than two percent variation in hue, providing strategic security for long‑term supply contracts. Eco‑conscious extraction recycles cutting water, and scheduled mine‑face rehabilitation keeps the landscape stable while meeting Iran’s latest environmental codes.
Safe arrival starts with professional packing. Each slab rests on foam sheets inside ISPM‑15 wooden A‑frames, with corner protectors and moisture‑barrier film shielding polished faces. Smaller tiles and mosaics are bulk‑palletised, while book‑matched sets travel in individual crates to prevent mix‑ups. Container layouts maximise weight distribution and minimise unused space, trimming freight costs and lowering breakage to under half a percent. Every crate label lists product code, batch number, thickness, and a QR link to QA reports, so installers can verify exact specifications before unpacking.
It is a translucent stone formed in mineral-rich caves, characterized by ivory-white to caramel hues and ideal for back-lit interior design.
Ivory Onyx enjoys a strong presence in international markets, particularly in regions with a high demand for luxury materials in construction and interior design. Countries such as the United States, United Arab Emirates, China, and European nations like Italy and France are significant consumers of Ivory Onyx.
