Stone Name: Kayon Blue Granite

Type: Natural Granite (Plutonic Igneous Rock)

Quarry Location: Jiangxi Province, China

Appearance:

Kayon Blue Granite features a fine-grained texture with a consistent bluish-grey tone resembling sesame grains (also referred to as “sesame blue” in the local market). The subtle blend of soft blues and greys, interspersed with microcrystalline minerals, gives it a clean, elegant, and uniform appearance suitable for both interior and exterior applications.

Surface Finish Options

• Polished – High-gloss finish that highlights the blue-grey crystals
• Honed – Matte finish for a softer look
• Flamed – Coarse texture for outdoor anti-slip use
• Bush-Hammered – Rough surface, good for public paving
• Sandblasted – Fine texture and slip-resistant
• Leathered – Softly textured, low-gloss with enhanced tactile appeal
• Tumbled – Worn edges for rustic design applications
• Sawn Cut – Raw surface ideal for heavy-duty flooring

Available Tile & Slab Sizes (cm)

• Tiles: 30×30, 60×30, 60×60, 80×40, 100×50, 120×60 cm
• Slabs: 240–300 cm (length) × 120–180 cm (height)
• Standard Thicknesses: 1.5 cm, 2 cm, 3 cm (other thicknesses on request)

Applications

• Interior & Exterior Flooring
• Wall Cladding
• Façade Panels
• Staircases
• Kitchen Countertops and Vanity Tops
• Urban Landscaping and Public Paving
• Monuments and Memorials

Maintenance Recommendations

• Sealing: Not always required due to low porosity, but recommended in stain-prone areas (e.g., kitchens)
• Cleaning: Use pH-neutral stone cleaners; avoid acid-based products
• Polished Surfaces: Wipe regularly to maintain shine
• Exterior Use: Flamed/bush-hammered/sandblasted surfaces require periodic cleaning to remove moss/dust
