Stone texture:
a natural pink to red‑toned granite quarried in Sardinia (around Luras and Nule), featuring a warm rose‑red base that can range from lighter pinkish hues to deeper, slightly brownish‑pink tones, with a lively but balanced pattern of darker mineral speckles and fine grey or black flecks that give the stone visual depth while maintaining an overall uniform appearance rather than strong linear veining; a medium‑ to coarse‑grained, tightly interlocking crystalline fabric that produces a dense, compact, and durable matrix with low water absorption and good mechanical strength, providing excellent resistance to wear, weathering, and thermal changes, and allowing for a range of finish options—polished, sawn, sandblasted, tumbled, or rockfaced—while retaining a naturally granular and tactile character.

Description

Rosa Nule Granite is a natural stone admired for its warm rose-red base, which can vary from lighter pinkish hues to deeper brownish-pink tones. This granite, quarried in Sardinia around Luras and Nule, Italy, is characterized by a lively yet harmonious pattern of darker mineral speckles interspersed with fine grey or black flecks, contributing to its visual depth. Despite its lively pattern, the stone maintains an overall uniform appearance without strong linear veining. The texture of the stone is medium- to coarse-grained with a tightly interlocking crystalline fabric, ensuring a dense, compact matrix.

Physical and Mechanical Properties

  • Water Absorption: 0.44% . Reduced porosity contributes to its low water absorption, enhancing durability.

  • Density: 2,595 kg/m³ . Indicates the compactness and robust nature of the stone.

  • Flexural Strength: 17.5 MPa . Suggests good resistance to bending, suitable for flooring and work surfaces.

  • Compressive Strength: 179.0 - 188.0 MPa . Reflects high resistance to crushing forces, making it ideal for structural applications.

  • Hardness: Generally high, indicative of its scratch resistance and durability.

  • Porosity: Low .Enhances durability and resistance to external weathering factors.

  • Slip Resistance: Depends on finish; rougher finishes offer higher slip resistance.

Chemical and Mineral Composition (Approximate % by Weight)

  • Quartz: 20-30% . Contributes to hardness and luster.

  • Feldspar: 50-60% . Essential for the pink to red hues and overall durability.

  • Biotite and Mica: 10-15% . Provides the darker mineral speckles and flecks.

  • Other Trace Minerals: Varies . Including minor amounts of iron oxide, which may influence color variations.

Usage and Applications

  • Countertops . Due to its durability and aesthetic appeal.

  • Flooring . Suitable for high-traffic areas thanks to its wear resistance.

  • Wall Cladding . Offers a striking visual impact in interior and exterior settings.

  • Monuments and Memorials . Durability and color retention suit commemorative applications.

Maintenance Guidelines

  • Cleaning: Regular cleaning with mild detergent and water.
  • Sealing: Periodic sealing to maintain low porosity and enhance stain resistance.
  • Avoid Harsh Chemicals: Use non-abrasive products to prevent surface damage.

Common Surface Finish Options

  • Polished: Offers a glossy, reflective surface that highlights the stone's colors and patterns.

  • Sawn: A more natural finish, retains the stone's granular texture.

  • Sandblasted: Provides a textured finish that improves slip resistance.

  • Tumbled: Creates an aged look with softer edges and a more rustic appeal.

  • Rockfaced: Maintains a rugged, natural appearance, suitable for exterior applications.

Rosa Nule Granite's unique aesthetic and robust properties make it a versatile and enduring choice for a wide range of architectural and design projects.
