Green Onyx is one of nature's most captivating stones. Quarried in Iran, this onyx features a distinctive light green base with warm white cloud-like patterns that flow freely across the surface. But what truly sets Green Onyx apart is its natural translucency — when backlit, the stone glows with an ethereal green light, creating a dramatic focal point that no other material can replicate.
In this detailed guide, we cover everything from geological origins to practical applications, helping you understand why Green Onyx has become a favorite among architects and designers for luxury projects worldwide.
Origin & Geology
Green Onyx is quarried in Iran, a country renowned for its rich deposits of high-quality onyx and travertine. The stone formed over thousands of years through the deposition of calcium carbonate from mineral-rich waters, creating the characteristic banding and cloud-like patterns. For a detailed geological overview, see our Green Onyx Encyclopedia page.
Unlike marble, which is metamorphic, onyx is a sedimentary stone. This means it forms in layers, with each layer capturing different mineral compositions that create the unique color variations and patterns we see in the finished slabs.
The green color comes from trace amounts of copper and other minerals present during formation. The warm white patterns are areas of pure calcium carbonate, creating a beautiful contrast that mimics clouds drifting across a verdant landscape.

The Backlight Advantage
The most remarkable property of Green Onyx is its natural translucency. Unlike most stones, Green Onyx allows light to pass through it, creating a stunning glowing effect when illuminated from behind. This makes it the perfect material for backlit feature wall cladding, bar fronts, reception desks, and decorative panels.
For backlit applications, we recommend using thinner profiles (5-10mm) reinforced with aluminum honeycomb backing. This provides the necessary strength while maximizing light transmission. LED panels are installed behind the stone, creating an even, warm glow that transforms the space.
The effect is particularly dramatic in hotel lobbies, luxury retail spaces, and high-end residential interiors. The stone's natural green color, combined with warm LED lighting, creates an atmosphere of sophistication and tranquility that no other material can achieve.

Pricing & Grades
Green Onyx is priced at ¥600-1,800/m², making it significantly more affordable than premium marbles like Statuario Venato while offering unique aesthetic properties that no other stone can match.
Pricing varies based on:
- Color consistency: Uniform green color commands premium pricing
- Pattern clarity: Distinct cloud patterns are more valuable
- Translucency: Higher translucency = better backlighting = higher value
- Slab size: Larger, unbroken slabs are more expensive
- Thickness: Custom thin profiles for backlighting cost more
For B2B buyers, we offer competitive factory-direct pricing with volume discounts for large projects. Contact us for current pricing and availability.
Maintenance & Care
Green Onyx requires more care than granite or quartzite due to its softer nature and sensitivity to acids. However, with proper maintenance, it will maintain its beauty for decades.
- Sealing: Apply penetrating sealer annually to protect against stains
- Cleaning: Use pH-neutral cleaners only; avoid acidic products
- Heat protection: Use trivets under hot pots and pans
- Scratch prevention: Use cutting boards; avoid dragging heavy objects
- Backlit installations: Ensure LED panels are accessible for maintenance
