• Compressive Strength: 80 - 100 MPa
• Hardness: Onyx generally falls around 3-4 on the Mohs scale.
• Porosity: It is typically low, contributing to its water resistance.
• Slip Resistance: Generally low in polished form but can be enhanced with specific finishes.

Chemical and Mineral Composition (approximate % by weight):

• Calcium Carbonate (CaCO₃): Major component as with most onyx stones.
• Silica (SiO₂): Present in smaller amounts.
• Iron Oxides (Fe₂O₃): Which contribute to its rusty brown and golden tones.
• Traces of other minerals: Provide additional coloration and banding effects.

Usage:

• Interior Cladding: Used for wall panels and feature walls due to its translucent quality, which can be backlit for stunning visual effects.

• Avoid Harsh Chemicals: As they can damage the stone's surface.

Cutting Sizes:

• Available in a variety of custom sizes, commonly cut to industry standards ranging from smaller tiles (30x30 cm or 12x12 inches) to larger slabs depending on the application.

Available Surface Finishes:

• Polished: Enhances its translucent properties and vibrant colors.
• Honed: Provides a softer, more matte appearance.
• Leathered: Adds texture while maintaining a matted look.
• Sandblasted: Creates a rougher surface for better slip resistance.

Desert Onyx’s unique aesthetic qualities and remarkable physical attributes make it a sought-after material for creating luxurious interior spaces. Its versatility in surface finishes and cutting sizes further enhances its appeal for various design requirements.
