STONE GUIDE 

Stone Types

Natural Stone

Natural stone represents millions of years of geological formation, offering unique patterns and characteristics that make each slab distinctive. These materials provide unmatched beauty and durability for both residential and commercial applications.

Key Characteristics:

  • Unique veining and color variations
  • Exceptional durability and longevity
  • Heat and scratch resistance
  • Increases property value
  • Requires periodic sealing for optimal performance

Sintered Stone

Sintered stone represents the latest advancement in stone technology, created through extreme heat and pressure processes that simulate natural stone formation. This innovative material offers exceptional performance characteristics.

Key Characteristics:

  • Ultra-compact surface
  • Extreme heat resistance (up to 1200°C)
  • UV stable and fade resistant
  • Hygienic and easy to clean

Suitable for indoor and outdoor applications

Engineered Stone

Engineered stone combines natural quartz crystals with polymer resins and pigments, creating a consistent and non-porous surface. This manufacturing process results in superior stain resistance and reduced maintenance requirements.

Key Characteristics:

  • Consistent color and pattern
  • Non-porous surface
  • Superior stain and scratch resistance
  • No sealing required
  • Available in wide range of colors and finishes
