Product Overview
Product Overview & Customization Capabilities

This natural green onyx marble features a soft, translucent jade-green background highlighted by organic golden-brown veining patterns. Quarry-sourced blocks undergo precision wire-sawing and high-grit automated polishing to yield surface finishes with gloss readings exceeding 95 GU. Known for high light transmittance, this translucent onyx stone is engineered for backlit architectural features, feature walls, and custom vanity tops.
Xiamen Smarter Stone Co., Ltd provides complete B2B manufacturing and processing services directly from our Xiamen stone fabrication plant. We offer gangsaw slabs in standard 10mm and 18mm thicknesses, alongside cut-to-size project tiles, mitered edge countertops, and CNC-carved decorative panels. To resolve raw material variation across large architectural supply orders, our production team performs pre-assembly dry-lay layouts, shade matching, and slab sequence numbering prior to final crate packing.

Quality Control & Inspection Standards
Our factory implements strict piece-by-piece inspection before export dispatch. Raw onyx blocks are scanned for micro-fissures and structural integrity before entering the gangsaw line. Slab thickness is monitored with digital calipers to keep variations strictly within +-1mm. Surfaces undergo multi-stage resin filling and mesh backing reinforcement to maximize structural stability during transit and installation.
Every green onyx slab order undergoes full dry-lay inspection under warm LED backlighting to verify light pass-through consistency, grain alignment, and veining continuity. Finished slabs are packed into ISPM-15 certified heat-treated wooden crates reinforced with corner protectors, high-density polyethylene foam dividers, and steel banding to withstand long-distance maritime freight.

FAQ
How do you manage veining continuity and slab selection for large-scale green onyx projects?
We source blocks from the same quarry vein and perform full factory dry-lays under targeted LED lighting. Slabs are color-matched, sequence-numbered, and documented with high-resolution photos for client review before crate packing, guaranteeing smooth veining transitions across adjacent panels.
What backlighting LED specifications and slab thicknesses are recommended for backlit onyx installations?
We recommend 10mm or 15mm polished slabs combined with uniform LED light panels (3000K-4000K positioned 50mm to 100mm behind the stone. This configuration prevents hot-spotting while maximizing light transmission across the green onyx marble matrix.
How should translucent green onyx be sealed and maintained in commercial settings?
Apply a penetrating fluoropolymer stone sealer before installation and reapply annually. Clean exclusively with pH-neutral stone cleaners. Avoid acidic chemicals or abrasive pads to prevent dulling the polished finish or etching the calcite-based surface structure under high-traffic use.
