In the realm of elite interior architecture, certain materials transcend utility to become works of natural art.
Blue Onyx is one such material, standing as one of the rarest and most visually captivating semi-precious stones.
Quarried in the Urmia region of northwest Iran, this stone is famous for its deep blue shades and gold-bronze veins.
Its dense cryptocrystalline structure and high mineral purity give it exceptional translucent properties.
When backlit, the stone transforms, casting a warm, ethereal glow that highlights the depth of its patterns.
This capability makes Blue Onyx a favored choice for luxury feature walls, custom bar tops, and upscale receptions.
Geologically, Blue Onyx is formed in cold spring waters through the slow deposition of silica and calcite minerals.
Over millennia, these mineral-rich waters slowly filtered through subterranean cavities, depositing microscopic bands.
The presence of specific minerals, such as iron oxides and copper compounds, resulted in the beautiful blue colors.
This slow deposition process ensures that the stone is dense, pore-free, and has high structural integrity.
At SherkatStone, we inspect and select only the highest backlit-grade blocks for processing.
The primary value of Blue Onyx lies in its ability to transmit light through its mineral crystal matrix.
This requires careful planning during the design, selection, and installation phases:
Light Source Selection: Cool white LEDs (4000K-5000K) highlight the blue tones, while warm LEDs (2700K-3000K) bring out the golden veins.
Uniform Illumination: Use custom LED panels to distribute light evenly and avoid hotspots behind the slab.
Maintenance Access: Design the mounting system to allow easy access for future LED maintenance.
Backing Reinforcement: Slabs are reinforced with clear epoxy and high-strength fiberglass mesh to ensure stability.
Blue Onyx is suited for focal points where its visual depth and light transmission can be fully appreciated:
Key B2B project applications include:
Backlit Feature Walls: Bookmatched panels in luxury hotels, presidential suites, and high-end residences.
Bespoke Bar Counters: Illumined countertops in fine dining venues, corporate lounges, and private clubs.
Luxury Vanity Tops: Highly polished vanity tops, powder room focal points, and design accents.
Decorative Inlays: Custom backlit columns, staircase accents, and furniture pieces.
In modern interior designs, architects frequently combine Blue Onyx with dark wood, brass accents, and minimalist surfaces.
The contrast highlights the natural stone's colors, making it the focal point of the space.
Additionally, its dense crystalline structure ensures that the stone retains its polish over long periods.
At SherkatStone, we operate strictly as a professional trade and sourcing coordinator.
We maintain direct agreements with advanced processing factories in major industrial hubs like Isfahan and Tehran.
This model allows us to source large volumes of high-quality Blue Onyx, ensuring uniform sorting and calibration.
Our quality check process starts at the quarry face in Urmia, where we inspect block integrity before extraction.
During processing, we monitor block cutting, epoxy filling, vacuum resin reinforcement, and polishing.
Each slab is physically inspected for edge straightness, corner angles, and light transmission quality.
We classify finished products into clear sub-grades (Super, Premium, Commercial) to ensure clients receive exactly what is specified.
Our trade coordination model also guarantees transparent communication. B2B buyers receive regular production updates.
For engineering compliance and architectural approval, our Blue Onyx is tested against international standards:
| Physical Property | Testing Method | Measured Value |
|---|---|---|
| Bulk Specific Gravity (Density) | ASTM C97 | 2.72 g/cm³ |
| Water Absorption | ASTM C97 | 0.10% |
| Compressive Strength (Dry) | ASTM C170 | 98 MPa |
| Compressive Strength (Wet) | ASTM C170 | 85 MPa |
| Modulus of Rupture | ASTM C99 | 9.5 MPa |
| Abrasion Resistance | ASTM C241 | 24.0 Ha |
We supply Blue Onyx in multiple commercial formats, matching your project's architectural requirements:
Gang-Saw Slabs: Available in 20mm and 30mm thicknesses, with dimensions reaching 2700mm x 1500mm.
Calibrated Tiles: Standard sizes including 300x600mm, 600x600mm, and 800x800mm.
Custom Panels: Cut-to-size panels machined to exact architectural specifications.
Raw Blocks: We export blocks ranging from 12 to 20 tons, inspected for internal cracks.
Our advanced processing yards use Italian gang-saws and multi-head polishing lines to ensure precise calibrations (+/-1mm).
Blue Onyx's dense structure allows for a variety of surface treatments:
Polished: Highlighted to a high gloss, showing the depth of the blue base and gold veins.
Honed: A smooth matte surface, suitable for subtle wall applications.
We use premium Italian epoxy resins matched to the stone's base color to ensure long-term stability.
Due to its calcium carbonate composition, Blue Onyx should be maintained with appropriate care:
Pre-Sealing: We recommend applying a premium penetrating sealer during installation to prevent staining.
pH-Neutral Cleaning: Clean surfaces with pH-neutral stone detergents; avoid acidic cleaners.
Periodic Resealing: Reapply penetrating sealers every 2 to 3 years in commercial environments.
Secure packaging is essential to prevent damage during international transit:
Wooden A-Frames: Heavy slabs are secured on fumigated wooden A-frames with protective rubber pads.
Wooden Crates: Calibrated tiles are packed in sturdy, foam-lined wooden crates.
Moisture Protection: Plastic sheets and desiccant packs are used to prevent moisture buildup.
We coordinate logistics through reliable routes for safe delivery:
Sea-Freight: Dispatched from Bandar Abbas (Shahid Rajaee Port) to major ports in Asia, Europe, and the Middle East.
Land-Transit: Dispatched via Norduz border (for Armenia/CIS) and Astara border (for Azerbaijan/Russia).
Customs Clearance: We provide full documentation including certificates of origin, SGS inspections, and clean bills of lading.
