Product Overview
Guanmay Stone supplies a curated selection of premium grey marble – a family of natural stones known in the Chinese market as 鱼肚灰 (Yú Dù Huī). These stones feature a cool grey to silver base with flowing white, silver-grey, and occasionally blue-grey veining that creates depth, movement, and visual elegance.
Market Names and Aliases:
This stone family is known by multiple names across different markets, all referring to the same or closely related material:
| Market Name | Notes |
|---|---|
| 鱼肚灰 (Yuduhui) | Primary Chinese market name – "fish belly grey" |
| Allure Bleu / Allure Silver | International trade name – blue-grey undertones |
| Armani Silver / Armani Grey | Premium designation – silver-grey with white veining |

The stone is characterised by:
Colour: Cool grey to silver background – ranging from misty light grey to deeper charcoal
Veining: Fine linear or cloud-like white quartz veins – organic, flowing patterns
Finish: High-gloss polished standard – honed, leathered, and brushed available
Texture: Fine-grained, dense crystalline structure – high-density calcitic marble
Quartzite Options:
For projects requiring superior durability, we also supply Super White Quartzite (also known as White Fantasy Quartzite or Calacatta Super White Quartzite). This Brazilian quartzite features a crisp white to light grey background with elegant deep grey veining, combining the luxurious appearance of Calacatta marble with the superior durability of quartzite. With Mohs hardness of 6.5–7, it is significantly more scratch and heat resistant than marble.

Customization Capabilities
Our fabrication capabilities cover the full spectrum of hotel and commercial architectural elements:
Exterior wall cladding and facades: Black granite's durability and resistance to the elements make it the preferred stone for building exteriors. Available in polished, flamed, or bush hammered finishes for different aesthetic and slip-resistance requirements.
Flooring: With Mohs hardness of 6.5–7, granite resists scratching and wear from heavy foot traffic. The polish on a well-maintained granite floor remains intact after decades of use.
Column cladding: Full-height black granite panels for structural and decorative columns – available in flat configurations.
Feature walls and background walls: Full-slab installations for hotel reception backgrounds, lobby feature walls, and commercial statement walls.
Surface finishes: Polished (high-gloss, enhances colour depth and veining), Honed (smooth matte), Flamed (textured, anti-slip for exterior flooring), Bush Hammered (textured, slip-resistant), Leathered (tactile, matte).
Quality Control & Inspection Standards
Grey marble and quartzite require rigorous quality control to ensure visual consistency and structural integrity for large-scale commercial and residential projects.
Block and slab selection: Each block is evaluated for colour consistency, veining distribution, and absence of structural defects. For large-scale projects requiring visual continuity – such as hotel lobbies and feature walls – slabs from the same block are batched and numbered for sequence-matched installation.
Fabrication quality:
Dimensional accuracy: Cut-to-size components verified against CAD drawings with +/-1mm tolerance
Surface finish: Polished finish inspected for uniform gloss (80°–100°); honed finish checked for consistent texture
Surface flatness tolerance: +/-0.3mm
Thickness tolerance: +/-0.5mm for countertops and slabs
Edge inspection: All edges verified for straightness and finish quality
Hole placement: Sink cutouts, faucet holes, and anchor holes confirmed to CAD coordinates
Packaging: Each finished piece is protected with film, corner guards, and foam padding. Slabs are packed in fumigated wooden bundles with plastic protection between each slab. Tiles and cut-to-size pieces are packed in strong seaworthy wooden crates with internal foam protection. All items are prepared for container shipment. Third-party inspection (SGS, BV) is available upon request.
