Testing
- Water Absorption:
- 0.23 By weight %
- Density:
- 2630 kg/m³
- Flexural Strength:
- 11.0 MPa
- Compressive Strength:
- 181.0 - 196.0 MPa
- Stone texture:
- medium- to coarse-grained and compact, composed of tightly interlocking crystalline minerals, classic Sardinian natural stone distinguished by its warm pink to rose-colored background, often blended with soft grey, beige, and occasional whitish tones, creating a balanced and inviting chromatic composition; the surface is animated by a dense distribution of black, dark brown, and grey mineral speckles, sometimes forming slightly porphyritic clusters that give the stone a gently mottled, cloud-like appearance rather than strong directional veining, resulting in a uniform yet lively aesthetic suitable for large applications.
Description
Rosa Limbara Granite is a natural stone from Sardinia, Italy, recognized for its medium to coarse grain and compact structure. The stone features a warm pink to rose-colored background mixed with soft shades of grey, beige, and occasional whitish tones. The surface boasts a dense array of black, dark brown, and grey speckles, sometimes forming slightly porphyritic clusters, creating a gently mottled, cloud-like appearance.

Chemical and Mineral Compositions (Approximate % by weight)
- Quartz: 20-30%
- Feldspar (mainly Orthoclase and Plagioclase): 60-75%
- Biotite: 5-10%
- Accessory Minerals (e.g., muscovite, hornblende): 2-5%
Usage
- Interior Applications: Countertops, flooring, wall cladding, and staircases
- Exterior Applications: Facades, paving, and monuments
- Decorative Elements: Column cladding, reception desks, and other interior décor
Maintenance
- Cleaning: Regular cleaning with a mild detergent and water; avoid acidic or abrasive cleaners
- Sealing: Recommended to enhance longevity and resistance to stains; typically once a year or as needed
- Polishing: Periodic polishing may be needed to maintain a glossy finish, depending on the traffic and usage
Available Common Surface Finish Options
- Polished: Offers a glossy and reflective finish, enhancing the stone's colors and patterns
