Onyx stone prices sit above marble and granite, driven by uniform translucency, absence of structural cracks, color and veining, slab dimensions, and sorting quality; rare colors such as jade green top the range. Quoted rates exclude cutting, fabrication, and transport, and backlit scopes price the lighting system and framing separately.

Onyx stone price ranges in the market
Onyx stone prices exceed marble and granite as a specialty luxury material. Pricing depends on color, translucency, slab dimensions, sorting quality, and supply source.
High-translucency onyx and rare colors like jade green sit in the highest price tier. Large uniform slabs for backlit panels cost more.
Quoted prices typically exclude cutting, fabrication, and transport. Backlit projects also price lighting systems and framing separately.
Before final purchase, review real slabs on site under natural and artificial light so color and texture shifts are visible before installation. Recording quarry, grade, and finish in the supply contract reduces return risk and workshop delay.
Periodic sealing, proper jointing, and neutral cleaning extend visual service life in wet and high-traffic zones. Document these routines in the handover manual from day one.
Outdoors, flamed or bush-hammered textures improve slip resistance. One to two percent drainage slope and expansion joints are mandatory for correct landscaping stone execution.

Factors affecting onyx stone pricing
Uniform translucency, absence of structural cracks, color and veining, slab dimensions, and thickness are primary pricing drivers. Backlit-suitable high-translucency slabs cost more.
Professional sorting and consecutive slabs from one batch increase supply cost but guarantee final visual quality. 1–2 cm thickness is standard for backlighting.
Order volume and delivery timing also affect final price. Onyx stock is limited and some colors are available only by pre-order.
Slab thickness must align with substrate design, fixing system, and structural dead load. In busy areas, honed or flamed finishes usually deliver more stable appearance than polish and simplify maintenance.
For accurate quotes, prepare area, thickness, finish, delivery point, and schedule. Warehouse slab viewing before financial commitment keeps delivered quality aligned with pro-forma pricing.
Color consistency on luxury projects requires professional sorting and consecutive slabs from one batch. Catalog photos alone without physical viewing carry high mismatch risk.

Onyx pricing vs other stones
Onyx typically costs more than marble and granite due to rarity and specialty application. Versus comparable imports, Iranian onyx is competitive in some grades.
Total onyx project cost includes stone, cutting, lighting, framing, and installation. Comparing only raw stone per-square-meter price gives an incomplete picture.
Emerald Stone's building stone price guide compares stone types at a glance.
On large projects, professional sorting and approved layout planning start at design phase. Emerald Stone provides batch technical reports and execution coordination alongside free stone engineering consultation.
Application drives stone choice more than aesthetics alone. Heavy-traffic floors, exterior facades, kitchen counters, and feature walls each need different quarry, grade, and finish specifications.
For feature walls and backlit panels, slab thickness and translucency must coordinate with lighting design from the start. Mockups before final execution are recommended on luxury scopes.

How to request an onyx price quote
For accurate quotes, send panel dimensions, required thickness, application type (backlit or decorative), and space photos. Viewing real slabs before financial commitment is essential.
At Emerald Stone, pricing quotes include consultation on slab selection matched to budget and application. Onyx stock is limited — warehouse status is checked before ordering.
Aligning architect, owner, and stone contractor before the final order prevents site stoppages. Phased delivery also reduces temporary workshop storage cost.
Batch technical reports covering absorption, compressive strength, and surface quality help architects decide confidently. Emerald Stone attaches these reports on sensitive scopes.
Stone price comparisons must use matching quality, thickness, and finish. Total ownership cost includes material, installation, sealing, and maintenance—not unit price alone.

Frequently asked questions
What is the price per meter of onyx?
Exact pricing depends on color, translucency, dimensions, and sorting quality and is not fixed. Request a direct quote from Emerald Stone for current ranges. Before final purchase, review real slabs on site under natural and artificial light so color and texture shifts are visible before installation. Recording quarry, grade, and finish in the supply contract reduces return risk and workshop delay.
Is onyx more expensive than marble?
Yes — onyx typically sits above marble in price tier. The difference reflects rarity, translucency, and specialty application requirements. Before final purchase, review real slabs on site under natural and artificial light so color and texture shifts are visible before installation. Recording quarry, grade, and finish in the supply contract reduces return risk and workshop delay.
What drives backlit onyx pricing higher?
Uniform translucency, large slab dimensions, absence of cracks, and rare colors are primary factors in higher backlit onyx project pricing. Before final purchase, review real slabs on site under natural and artificial light so color and texture shifts are visible before installation. Recording quarry, grade, and finish in the supply contract reduces return risk and workshop delay.
Does the price include the lighting system?
No — raw or fabricated stone is priced separately from light panels, framing, and installation. Complete estimates must include all components. Before final purchase, review real slabs on site under natural and artificial light so color and texture shifts are visible before installation. Recording quarry, grade, and finish in the supply contract reduces return risk and workshop delay.
Is Iranian onyx cheaper than imported?
In some grades yes, but quality and translucency matter more than source alone. View real samples before comparing prices. Before final purchase, review real slabs on site under natural and artificial light so color and texture shifts are visible before installation. Recording quarry, grade, and finish in the supply contract reduces return risk and workshop delay.
