Anari Grain Granite: Technical Overview and Applications
Anari Grain Granite is a distinctive natural stone quarried in the Birjand and Darmian region of South Khorasan Province, Iran. This Iranian granite is recognized by its dark olive-green to deep green background, interspersed with small burgundy-to-black crystalline grains that resemble pomegranate seeds, giving the stone its characteristic name.
Key Technical Characteristics
The stone exhibits a medium to coarse-grained igneous structure with high density and extremely low, near-zero open porosity characteristic of dense igneous granites. Technical data indicates water absorption of approximately 0.02% to 0.4% (very low), making it highly resistant to moisture penetration and suitable for wet environments. The compressive strength is reported at approximately 2,250 kg/cm², providing reliable performance under heavy loads and high-traffic conditions.
In terms of finish options, Anari Grain Granite is commonly processed into polished, leathered, honed, and flamed surfaces. Polished finishes enhance the depth of the green groundmass and the contrast of the red grains, while leathered and flamed finishes provide a more tactile, matte surface suited to exterior applications where slip resistance is a consideration. Processing is typically carried out as cut, calibrated, and polished work, and the stone is supplied in 2 cm and 3 cm thicknesses, with available dimensional formats including tile, slab, longitudinal cut-to-size, stair treads, facade pieces, and flagstone patterns.
Architectural Applications
Due to its dense structure and low water absorption, Anari Grain Granite is used across a wide range of interior and exterior applications. Common uses include flooring in lobbies, commercial spaces, parking areas, and other high-traffic areas, as well as wall cladding, stair treads, kitchen countertops, and bathroom surfaces. For exterior applications, the flamed and leathered finishes offer enhanced slip resistance and weather durability, making the stone suitable for facades, paving, and landscape elements.

Which One Should We Choose?
- If high compressive strength and very low water absorption for heavy-traffic outdoor flooring or parking lots are important, Anari Grain Granite is more suitable, though natural variations in red and green hues and mineral streaks require careful batch inspection prior to loading.
- If an indoor decorative statement piece with a dramatic veined texture is required, Infinity Gold Granite is more suitable, keeping in mind that its higher water absorption and porosity limit its use to indoor spaces away from constant moisture.
- If a high-end imported granite with diverse black, gold, and silver tones for luxury interior and exterior applications is important, Titanium Granite Brazil is more suitable, while acknowledging that import logistics and material costs are higher.
- If a local green-spectrum granite with book-match capability and up to 4 cm thickness options is needed, Delicate Granite Stone is more suitable, though its slightly wider porosity range requires checking specific finish types for exterior exposure.
- If maximum versatility across classical and modern facades, columns, and heavy-traffic flooring with diverse color choices is important, Birjand Granite Stone is more suitable, noting that mechanical properties vary across different subspecies within the region.
Selection and Installation Considerations
When specifying Anari Grain Granite, attention should be paid to batch consistency, as the density and distribution of red grains can vary between extraction lots. Due to its high specific weight, the stone requires precise substrate preparation and appropriate adhesive systems during installation. In ventilated facade systems, proper anchoring and detailing are essential to ensure long-term stability. Polished surfaces in wet areas may benefit from anti-slip treatments to maintain safety without compromising appearance.
For routine care, periodic application of a penetrating sealer is generally recommended for honed and leathered surfaces, which are more open-textured than polished ones, and cleaning with a neutral, non-acidic detergent helps preserve the natural finish.
Anari Grain Granite represents a technically sound and visually distinctive option within the Iranian granite family, suitable for projects that require a combination of durability, low maintenance, and a unique natural character grounded in the mineral heritage of South Khorasan.
