Grey Fossil Limestone Pavers are premium-grade natural stone quarried and hand-selected directly from the Middle East by Citadel Stone. Formed over hundreds of millions of years on ancient ocean floors, this exceptional limestone is defined by its distinctive cool blue-grey base tone and its extraordinary surface — alive with the preserved imprints of marine fossils: crinoids, ammonites, shell fragments, and ancient sea creatures embedded permanently into the stone during the fossilisation process.
Every single paver is a geological record — a one-of-a-kind artefact that no tile factory, porcelain manufacturer, or synthetic material can ever replicate. The fossil patterns are dense, varied, and visually arresting, giving Grey Fossil Limestone Pavers a natural drama and depth that instantly becomes the focal point of any space.
Available in many finishes that preserves the stone’s authentic quarried character — and in every other finish to suit your precise vision — these pavers perform beautifully across kitchens, bathrooms, living rooms, patios, driveways, pool surrounds, feature walls, and large-scale commercial projects.
It is a classic Grey Fossil Limestone. Key visual characteristics visible in the stone:
Fossil limestone is widely available, but quality varies enormously. At Citadel Stone, every block is hand-inspected at the quarry for fossil density, structural integrity, and colour consistency before a single cut is made. Only the finest stone — with rich, well-preserved fossils, consistent grey tones, and zero structural defects — reaches your order.
| Technical Parameter | Standard | Value | Performance Note |
| Density (g/cm³) | S.N.S 1393 | 2.90 | Exceptionally high density — one of the densest limestones available, delivering superior resistance to surface wear and structural stress. |
| Water Absorption (%) | S.N.S 1393 | 1.27 | Ultra-low absorption — outstanding resistance to moisture, staining, frost, and freeze-thaw cycling. Ideal for wet areas, pool surrounds, and outdoor paving in all climates. |
| Compressive Strength (N/mm²) | S.N.S 1396 | 63.64 | Exceptional structural strength — nearly double that of standard limestone. Handles heavy vehicular loads, commercial foot traffic, and demanding structural applications with ease. |
| Flexural Strength (N/mm²) | S.N.S 1394 | 8.01 | High resistance to bending forces — reduces cracking and fracture risk significantly in large-format paving and wall cladding installations. |
| Abrasion Resistance (mm) | S.N.S 1169 | 1.59 | Excellent surface hardness — fossil patterns and stone surface retain their appearance and integrity even under sustained high-traffic use. |
| Modulus of Rupture (N/mm²) | S.N.S 1395 | 7.96 | Strong structural integrity under concentrated loads — dependable in challenging commercial and outdoor environments. |
Grey Fossil Limestone’s compressive strength of 63.64 N/mm² places it among the strongest natural limestones available — nearly twice the strength of standard limestone varieties. It is suitable for the most demanding residential and commercial paving applications.
Grey Fossil Limestone Pavers are listed in a Polished Finish, which beautifully showcases the fossil detail in its most authentic form. All other finishes are available to order:
| Finish | Description | Best For |
| Natural / Sawn ★ | Raw, unprocessed surface that fully exposes the fossil detail in its most authentic and tactile form. Slightly textured, naturally anti-slip. | Exterior paving, feature walls, rustic interiors |
| Honed | Smooth, matte surface that softens the grey tones while retaining the fossil visibility — a refined, understated finish. | Living rooms, hallways, bathrooms, patios |
| Polished | High-gloss mirror finish that dramatically intensifies the fossil patterns and grey tones — the most visually striking option. | Hotel lobbies, statement floors, luxury interiors |
| Antique / Tumbled | Weathered, aged appearance with rounded edges and softened fossil relief — classic and characterful. | Mediterranean gardens, courtyard paving, period interiors |
| Bush-Hammered | Mechanically textured, deeply pitted surface — maximises anti-slip performance while preserving fossil character. | Driveways, pool decks, high-risk wet areas |
| Leathered | Soft, tactile texture with low reflectivity — sophisticated and durable, with subtle fossil detail visible throughout. | Contemporary kitchens, outdoor entertaining zones |
| Sandblasted | Uniform, matte anti-slip surface created by fine sand abrasion — highly durable under outdoor exposure. | Commercial walkways, steps, exterior paving |
| Brushed | Wire-brushed surface that reveals the fossil texture with a natural, slightly worn appearance — rustic yet refined. | Outdoor patios, garden paths, pool surrounds |
