Turquoise Green Granite

Turquoise Green Granite is a natural stone quarried in the Khorasan region near Mashhad, Iran. This granite is prized for its striking blue-green background, accented by golden-rusty veins and white quartz lines. It combines high durability with a distinctive aesthetic that suits both contemporary and classic architectural projects.

Key Features of Turquoise Green Granite

Turquoise Green Granite offers excellent technical performance. Its water absorption is very low, between 0.2 and 0.35 percent by weight, which provides strong resistance to water penetration and freeze-thaw cycles. The compressive strength ranges from 160 to 180 MPa, and flexural strength is 12 to 15 MPa. With a Mohs hardness of 6 to 7 and low porosity, this granite is highly resistant to abrasion and wear. The mineral composition includes quartz (25-30%), feldspar (55-60%), mica (5-8%), and iron oxides (2-4%). The turquoise color is mainly due to microcrystalline feldspars and copper-bearing minerals.

• Low water absorption: 0.2 to 0.35 percent
• High compressive strength: 160 to 180 MPa
• Flexural strength: 12 to 15 MPa
• Density: 2650 to 2750 kg/m3
• Mohs hardness: 6 to 7
• Low porosity and high abrasion resistance
• Crystalline texture, medium to coarse grain

Architectural Applications

Turquoise Green Granite is suitable for a wide range of interior and exterior applications. Indoors, it is used for kitchen countertops, washbasin surfaces, wall cladding, staircases, fireplace surrounds, and feature walls. It also works well for elevator cladding and reception desks. Outdoors, it is applied in building facades, paving, landscape elements, and sculptures. Its low water absorption and high strength make it reliable in diverse climatic conditions.

• Kitchen countertops and islands
• Interior and exterior wall cladding
• Stairs and steps
• Fireplace surrounds
• Building facades
• Paving and landscape elements
• Elevator cladding and feature walls

Comparison with Birjand Green Granite

When compared with Birjand Green Granite, also known as Forest Green Granite, Turquoise Green Granite shows clear visual and technical differences. Birjand Green typically has a darker green background with yellow and white veins, giving it a warmer, more earthy character. Turquoise Green Granite, by contrast, features a blue-green background with golden-rusty veins, creating a cooler, more vibrant appearance. Both stones have very low water absorption and high compressive strength, making them suitable for interior and exterior use. However, Turquoise Green Granite is rarer and offers a more distinctive color palette. Birjand Green Granite is available in several uniform sorts, which can be advantageous for large projects requiring consistent patterning. The choice between them depends on the design intent, desired visual effect, and specific project conditions.

Selection and Installation Considerations

When selecting Turquoise Green Granite, it is important to choose uniform batches to maintain visual consistency, as natural variations in veining and color can occur. The stone is available in several finishes, including polished, honed, leathered, flamed, and sandblasted. Polished and honed finishes are often preferred for interior applications, while flamed or sandblasted surfaces provide better slip resistance for exterior paving. During installation, precise joint alignment is essential for large surfaces. Regular maintenance with pH-neutral stone cleaners is recommended, and acidic products should be avoided to preserve the surface luster. Periodic sealing helps protect the stone from staining, especially in areas exposed to oils or colored liquids.

Turquoise Green Granite stands out as a durable and visually unique natural stone. Its low water absorption, high strength, and distinctive blue-green color make it a strong choice for luxury interiors, exterior facades, and export projects. With proper selection and care, it delivers lasting performance and architectural character.
