Purple Diamond Granite

Purple Diamond Granite is a medium to coarse-grained natural stone, quarried in the Yanshan District of Chengde, Hebei province, China. The granite features a sophisticated color palette that combines hues of brownish-purple, pale green, and grey. The stone's polished crystalline surface finish adds elegance and depth, making it a popular choice for various architectural and decorative applications.

Physical and Mechanical Properties:

• Water Absorption: Typically low, generally around 0.2% to 0.4%, which suggests excellent resistance to moisture.

• Density: Approximately 2,660 to 2,740 kg/m³, indicating a relatively heavy and durable material.

• Flexural Strength: Typically ranges from 11.5 to 13.5 MPa, demonstrating good resistance to bending and fractures.

• Compressive Strength: Often between 155 to 175 MPa, reflecting the granite's high ability to withstand compressive forces.

• Hardness: Typically around 6 to 7 on the Mohs scale, indicating significant scratch resistance.

• Porosity: Generally low, with values around 0.2% to 0.4%, signifying its dense nature.

• Slip Resistance: The polished finish may have moderate slip resistance, with a coefficient of friction typically ranging from 0.4 to 0.6.

Chemical and Mineral Composition (% by Weight):

• Quartz: 20-30%
• Feldspar (Orthoclase and Plagioclase): 50-60%
• Mica (Biotite and Muscovite): 5-10%
• Accessory Minerals (e.g., Iron Oxides, Zircon): 2-5%

The chemical composition may slightly vary based on the specific quarry site within the region.

Usage:

Interior Applications:

• Kitchen Countertops
• Vanity Tops
• Flooring (Interior)
• Wall Cladding

Exterior Applications:

• Facades
• Monuments
• Outdoor Paving

Decorative Purposes:

• Table Tops
• Staircases
• Artistic Sculptures

Maintenance:

• Regular cleaning with pH-neutral cleaners is recommended to preserve the polished surface.
• Sealing may be advisable every few years to enhance stain and moisture resistance.
• Avoid abrasive cleaning tools that might dull the polished finish.

Cutting Sizes (cm):

• Slabs: Commonly available in sizes such as 240 x 120 cm, but custom sizes can be accommodated as per project needs.
• Tiles: Standard tile sizes include 30 x 30 cm, 60 x 60 cm, 60 x 30 cm, and custom sizes upon request.

Available Common Surface Finish Options:

• Polished: Offers a glossy surface with mirror-like reflection, enhancing the stone's colors and patterns.
• Honed: Provides a smooth, matte finish, reducing glare and creating a more subtle appearance.
• Brushed: Delivers a textured finish with a soft, weathered look.
• Flamed: Presents a rough surface ideal for exterior applications, increasing slip resistance.

Purple Diamond Granite is a versatile and aesthetically appealing choice for various architectural and decorative uses. Its combination of mechanical robustness, unique color palette, and enduring beauty makes it a preferred material for both indoor and outdoor applications. Proper maintenance ensures its longevity and retains its polished appearance.
