Green Onyx | Bespoke Feature Stone Tiles (Custom Sizes & Formats)

Green Onyx is one of the most atmospheric and visually striking translucent stones available, defined by layered emerald, jade, mint and crystalline white mineral formations. Its calcite structure allows light to pass through the stone, creating a glowing, dimensional effect when backlit — a quality that sets it apart from opaque green marbles and quartzites.   
Each tile is crafted to order, allowing you to choose custom sizes, formats and finishes. Ideal for spa interiors, illuminated feature walls, bar fronts, boutique hotels and luxury residential spaces, Green Onyx transforms interiors with depth, movement and sculptural elegance.

Stone Characteristics 

• Layered emerald, jade, mint and white mineral bands with natural translucency

• Formed through mineral‑rich water deposition in cave systems over thousands of years (banded calcite/aragonite)

• Colour derived from copper compounds and chlorite minerals in groundwater

• Dramatic glow when backlit — illumination reveals internal movement and crystalline depth

• Soft stone with lower flexural strength; often resin‑reinforced or mesh‑backed for stability

• Responds dynamically to warm or cool lighting, shifting between jade, honey and emerald tones

Finishes Available

• Polished (maximum luminosity)

• Honed (soft matte, diffused glow)

• Boutique hotel lobbies and luxury commercial interiors

• Decorative accents, vanities and statement areas

Why Choose Green Onyx? 

Green Onyx behaves as an architectural lighting material, not just a decorative stone. Its translucent calcite layers transmit light internally, creating depth and glow impossible to achieve with opaque stones like Verde Alpi marble or green granite. Designers choose Green Onyx for its ability to soften contemporary interiors, introduce atmospheric warmth, and create dynamic visual movement that changes with lighting temperature and intensity.
