Testing

Water Absorption:
0.20 %
Density:
2620 kg/m³
Flexural Strength:
12.5 MPa
Compressive Strength:
152.0 MPa
Stone texture:
an elegant grey natural Bearing monzogranite biotite characterized by a medium to dark grey background, interspersed with lighter grey and white mineral flecks that create a subtle, evenly distributed speckled pattern across the surface. The stone’s overall appearance is refined and balanced, offering a neutral yet sophisticated aesthetic suitable for both contemporary and traditional architectural applications. In terms of texture and structure, Gris Zarza Granite is a dense, compact igneous rock composed primarily of quartz, feldspar, and mica, forming a fine- to medium-grained crystalline matrix. This structure provides excellent durability, low porosity, and high mechanical strength, making it suitable for heavy-use areas. When polished, the stone develops a smooth reflective surface that enhances its grey tones and mineral contrasts, while alternative finishes such as honed, flamed, sandblasted, or bush-hammered highlight its natural granular texture and structural solidity, making it ideal for flooring, countertops, wall cladding, exterior paving, and decorative architectural elements.
