Stone Information: Core Characteristics

Pietra Gray is a natural marble, a metamorphic rock formed under immense heat and pressure from sedimentary carbonate rocks, primarily limestone . Its defining characteristic is its rich, deep grey background, which can range from charcoal to a softer, slate-like grey, often dramatically contrasted by fine white, silver, or lighter grey veining .

• Type: Natural Stone (Marble)

• Origin: Primarily quarried in Iran, known for producing some of the world's most distinctive grey marbles . Specific regions within Iran are known for variations in veining and depth of color.

• Composition: Primarily composed of Calcite (approximately 90%), with smaller amounts of Dolomite (around 5%) and Quartz (around 3%) . The presence of other minerals contributes to its grey color and veining.

• Coloration: Ranges from deep charcoal grey to lighter, slate-grey tones. The veining can be subtle, resembling fine white or silver threads, or more pronounced, creating intricate patterns. Color consistency can vary between blocks and quarries, emphasizing the natural uniqueness of each piece.

• Texture: Generally a fine-grained stone, though its appearance can be softened or enhanced by different finishing techniques. The veins can sometimes give it a visual texture, even on a smooth surface.

• Hardness (Mohs): Typically rated between 3-4 on the Mohs scale. As a marble, it is softer than granite or quartzite and is susceptible to scratching and etching from acidic substances .

• Density: Generally ranges from 2.5 to 2.7 g/cm³ .

• Porosity: Marble is moderately porous, meaning it can absorb liquids if not properly sealed. This makes sealing a crucial step for applications like countertops and floors to prevent staining .

Available Slab Size(s)

Pietra Gray is primarily available in slab form, allowing for expansive and seamless applications.

• Standard Slab Dimensions: Typical large slab sizes generally range from approximately 260cm to 300cm (about 102 to 118 inches) in length and 160cm to 180cm (about 63 to 71 inches) in width . These dimensions are ideal for creating dramatic feature walls or large countertops with minimal seams.

• Common Thicknesses: Slabs are most commonly available in thicknesses of 2cm (¾ inch) and 3cm (1 ¼ inch). Thicker slabs (e.g., 4cm or 6cm) can often be produced for specific design needs, sometimes achieved by laminating thinner slabs . The choice of thickness depends on the application, with 3cm often preferred for countertops for added durability and visual weight.

Available Tile Size(s)

While slabs are common for large-scale projects, Pietra Gray is also processed into tiles for more versatile applications.

• Popular Tile Dimensions: Commonly found tile sizes include:

• Squares: 12"x12" (30x30cm), 24"x24" (60x60cm).

• Rectangles: 12"x24" (30x60cm), 18"x36" (45x90cm).

• Custom Sizes: Many suppliers can produce custom tile dimensions upon request.

• Thickness: Tiles are typically available in thicknesses of 1cm (⅜ inch) to 2cm (¾ inch), with thicker options for high-traffic floor areas.

Available Surface Finishes

The finish applied to Pietra Gray significantly impacts its aesthetic and tactile qualities, influencing its suitability for different design applications.

• Polished: This finish results in a high-gloss, reflective surface that intensifies the grey tones and makes the veining pop, creating a luxurious and dramatic effect. It's often used for feature walls, countertops where a sleek look is desired, and low-traffic flooring .

• Honed: A matte, non-reflective finish that provides a softer, more subdued appearance. Honed Pietra Gray has a sophisticated, velvety feel and is less prone to showing fingerprints or minor scratches than polished surfaces. It offers better slip resistance, making it an excellent choice for flooring, walls, and countertops, especially in modern and minimalist designs .

• Brushed/Leathered: This finish uses abrasive brushes to create a textured, slightly uneven surface. It enhances the natural tactile qualities of the marble and can give it a softer, more organic feel. This finish is excellent for countertops and flooring, offering a good grip and a contemporary yet natural look .

• Sandblasted: A process that uses high-pressure sand to create a very rough, non-slip texture. This finish is ideal for outdoor paving or areas requiring maximum slip resistance, though less common for interior marble applications where a smoother finish is usually preferred.
