Commercial Stone Comparison
Green Onyx vs Primavera Marble: Specifying Green Stone for Commercial Spaces
Green Onyx and Primavera Marble are the two green natural stones in Apexstone's commercial programme. One is translucent and backlit; the other is opaque and jade-like. This comparison helps architects and hotel procurement teams choose the right green stone for each commercial surface.
Material Comparison
Two Green Stones, Two Engineering Problems: A Side-by-Side Specification Guide
Apexstone supplies two green natural stones for commercial projects: Green Onyx and Primavera Marble (冷翡翠). They look similar in a photograph - both are green, both are premium natural stone, both come from Chinese-supplied quarries. But they are fundamentally different materials with different engineering requirements, different maintenance cycles, and different price architectures. Green Onyx is a translucent cryptocrystalline quartz stone that transmits light at 10-20 mm thickness, enabling backlit installations that no other stone can achieve. Primavera Marble is an opaque calcite marble whose chromium-rich green body reads as polished jade under any lighting condition. Choosing between them is not a matter of preference - it is a technical specification decision that affects the structural engineering, electrical system, maintenance schedule, and budget of the entire commercial project.
This comparison is written for architects, interior designers, and hotel procurement teams who need to specify green stone for commercial spaces. We cover four application zones - hotel lobby feature walls, bar and reception counters, restaurant feature walls, and spa spaces - and break down the engineering cost, colour stability, maintenance cycle, and price difference for each. Green Onyx slab sizes up to 3000x1800 mm (118x71 inch), panel thickness 10-20 mm (3/8-3/4 inch), lead time 25-35 days from drawing approval. Primavera Marble slab sizes up to 3000x1800 mm (118x71 inch), panel thickness 10-30 mm (3/8-1-1/4 inch), lead time 25-35 days. Both stones are available with polished, honed, or brushed finishes. FOB Xiamen or DDP delivery to 42+ countries since 2002.

Four Decisions That Separate a Smart Green Stone Specification from an Expensive Mistake
Translucent vs Opaque: The Engineering Cost Difference
Green Onyx is translucent - light transmits through the stone at 10-20 mm (3/8-3/4 inch) thickness. This property enables backlit installations but requires a cavity behind the stone housing LED panels, drivers, wiring, and an access panel. The combined wall system (stone + LED + frame + wiring) weighs 50-65 kg/m2 and costs 60-80% more than a standard stone cladding installation. Primavera Marble is opaque - light does not transmit. The stone is installed as standard wall cladding on adhesive or mechanical anchors, with no cavity, no LED, and no access panel. Wall system weight is 25-35 kg/m2. For a 50 m2 (538 ft2) lobby feature wall, the Primavera installation saves USD 15,000-25,000 in LED system and structural frame costs compared to Green Onyx. The decision is not which stone looks better - it is whether the project budget supports the lighting infrastructure that backlit onyx requires.
Colour Stability Under Commercial Lighting
Green Onyx shifts colour dramatically depending on the LED behind it: 2700K produces amber-green warmth, 4000K produces vivid emerald, 5000K+ washes out the green to tinted glass. This means the hotel operator can change the lobby ambience by adjusting the LED colour temperature - but it also means the stone looks different from the sample the designer approved. Primavera Marble's chromium-rich green body is stable under all light sources. Under 2700K it reads as deep jade. Under 5000K it reads as vivid emerald. The shift is noticeable but far less extreme than onyx. For hotel brands with strict visual identity standards, Primavera provides predictable colour across all properties. For hotel brands that want flexible ambience programming, Green Onyx offers a dynamic surface no opaque stone can match.
Maintenance Cycles: 5 Years vs 15 Years
A backlit Green Onyx wall has a 5-7 year maintenance cycle: LED panels rated for 50,000 hours will need replacement, requiring access through the maintenance panel. In an operating hotel, this means scheduling a lobby wall service during low-occupancy periods. The LED driver may fail earlier than the panels - budget for driver replacement at year 3-4. Primavera Marble wall cladding has a 15+ year maintenance cycle: the stone itself needs no electrical maintenance. Resealing is required every 5-7 years for polished surfaces in dry areas, but this is a surface treatment, not a system overhaul. For hotel facilities managers who already maintain dozens of building systems, eliminating the LED lifecycle from the stone wall is a significant operational advantage.
Price Architecture and Project Budgeting
Green Onyx slab prices run 3-4x higher than Primavera Marble per square metre at the quarry. A premium-grade Green Onyx slab (3000x1800 mm / 118x71 inch) costs USD 800-1,200 per m2 at FOB; a premium-grade Primavera Marble slab of the same size costs USD 200-350 per m2. Add the LED system cost (USD 150-300 per m2 including panels, drivers, and wiring) and the structural frame premium (USD 50-100 per m2), and the total installed cost per m2 of backlit Green Onyx reaches USD 1,000-1,600 versus USD 250-400 for Primavera wall cladding. For a 200-room hotel with a 50 m2 (538 ft2) lobby feature wall, choosing Primavera over Green Onyx saves USD 40,000-60,000 in the lobby alone - enough to upgrade all 200 guest bathroom vanity tops from engineered stone to natural marble.
Applications
Where Each Green Stone Belongs in Commercial Spaces
Hotel Lobby Feature Walls
Green Onyx and Primavera Marble take fundamentally different approaches to the same lobby wall. Green Onyx demands a backlit cavity behind the stone - the translucent onyx becomes a light source, glowing with warm LED backlighting at 2700-3000K. The effect is dramatic and immersive: guests walk into a lobby where the wall itself radiates green light. Primavera Marble, by contrast, is opaque. It relies on front-lit illumination - the emerald green surface reflects lobby lighting rather than transmitting it. The effect is quieter but more controllable: the stone reads as polished jade, sophisticated and grounded. For lobbies under 4 metres (13 ft) ceiling height, Primavera's reflective quality can make the space feel taller. For lobbies over 5 metres (16 ft), Green Onyx's backlit glow creates a sense of arrival that reflective stone cannot match.
Bar & Reception Counters
Both stones work as bar counter fronts and reception desk surfaces, but the installation requirements diverge sharply. Green Onyx bar tops at 20 mm (3/4 inch) thickness transmit light along the counter edge when backlit, creating a jewel-box glow that draws guests toward the bar. The LED system behind the counter must be rated IP67 for wet areas and 50,000+ hours for commercial operation. Primavera Marble bar tops at 20 mm (3/4 inch) thickness provide a solid emerald surface that reflects ambient lighting - no LED integration needed, no cavity engineering, no access panel requirements. For a hotel with 3 bar counters, the Primavera installation costs roughly 40% less than Green Onyx because it eliminates the lighting system entirely. The trade-off: Primavera cannot achieve the nighttime drama that backlit onyx delivers.
Restaurant & Dining Feature Walls
In restaurant interiors, the choice between these two green stones comes down to lighting strategy and maintenance cycle. Green Onyx feature walls in dining spaces create a warm, intimate ambience when backlit at 2700K - the green glow enhances food presentation and softens the dining atmosphere. However, the LED system behind a restaurant onyx wall runs 12-16 hours daily, requiring thermal management and a maintenance access panel. Primavera Marble feature walls in restaurants provide a stable emerald backdrop that does not change with lighting conditions. The chromium-rich green body reads consistently under both daylight and warm restaurant lighting. For high-turnover restaurants where maintenance windows are tight, Primavera eliminates the LED lifecycle question entirely.
Spa & Wellness Spaces
Spa environments benefit from both stones but in different zones. Green Onyx partition screens at 10 mm (3/8 inch) thickness create semi-transparent dividers between treatment areas - the backlit panels glow softly, maintaining visual connection while adding privacy. The LED system must be IP67-rated for humidity resistance. Primavera Marble vanity tops and wall cladding in spa wet areas provide a jade-like surface that harmonizes with chrome fixtures and white towels. At 18-20 mm (3/4 inch) thickness with honed finish, Primavera vanity tops resist water staining and require resealing every 3-5 years. For a spa with 8 treatment rooms, using Primavera for all vanity surfaces and Green Onyx for a single partition screen in the relaxation lounge balances impact with practicality.

Specification Process
The Specifier's Decision Sequence: From Backlit Requirement to Final Stone Selection
The decision sequence below is the specification workflow for a commercial project considering both green stones. Each step narrows the choice until the right stone is locked to the right surface.
- ✓
Step 1: Identify the Backlit Requirement
Determine whether the design calls for a luminous wall surface (Green Onyx with LED backlighting) or a reflective stone surface (Primavera Marble with front-lit illumination). If the architect's rendering shows a glowing wall, only Green Onyx can deliver it. If the rendering shows a polished green stone wall, either material works - but Primavera costs 60-80% less installed.
- ✓
Step 2: Confirm the Structural Budget
A backlit Green Onyx wall system weighs 50-65 kg/m2 (10-13 lbs/ft2) including stone, LED panels, frame, and wiring. The wall substrate must be engineered by a structural engineer. A Primavera Marble wall cladding system weighs 25-35 kg/m2 (5-7 lbs/ft2) and installs on standard adhesive or mechanical anchors. If the structural budget cannot support the additional load, Primavera is the only viable option.
- ✓
Step 3: Evaluate the Maintenance Window
Commercial Green Onyx installations require LED replacement every 5-7 years (50,000-hour rated panels). The access panel must be reachable without dismantling the wall. Primavera Marble requires resealing every 5-7 years but no electrical maintenance. For hotels with limited maintenance windows, Primavera eliminates an entire maintenance category.
- ✓
Step 4: Compare Total Installed Cost
Request a side-by-side quotation: Green Onyx slab cost + LED system + structural frame + access panel engineering vs Primavera Marble slab cost + standard cladding installation. For a 50 m2 (538 ft2) lobby wall, the typical difference is USD 40,000-60,000. Decide whether the backlit effect justifies the premium for each specific surface.
- ✓
Step 5: Mix or Match Across Surfaces
Many commercial projects use both stones: Green Onyx for the single most dramatic surface (lobby feature wall or bar counter front) and Primavera Marble for secondary green stone surfaces (spa vanities, restaurant accent walls, corridor cladding). This hybrid approach delivers the backlit impact where it matters most while controlling cost on supporting surfaces.
