Onyx Slab Overview
Onyx is a banded variety of chalcedony prized for its natural translucency and rich internal colour layers. When backlit, an onyx slab reveals depth, movement and glow that transforms any space into a living work of art. At Lumahstone we select only premium onyx block with consistent banding, minimal inclusions and excellent light transmission.
Natural Formation and Unique Translucent Properties
Onyx forms in low-temperature hydrothermal veins where silica-rich waters deposit layer after layer of microcrystalline quartz. The resulting stone is dense yet semi-translucent, allowing light to pass through in ways that make colours appear to float within the material. This optical quality sets onyx apart from marble or granite and makes it the material of choice when architects and designers want to create mood, drama and a sense of depth.
Backlit Onyx Wall Detail for Luxury Interiors
A properly engineered backlit onyx wall becomes the focal point of any interior. We recommend 15–20 mm thickness for most backlit applications, paired with high-CRI LED systems placed 80–120 mm behind the slab. Our slabs are pre-selected for uniform light diffusion so that veining reads beautifully whether the light is on or off.

Onyx Slab Calculator Guide
To estimate your requirement:
- Measure the total surface area in square metres.
- Add 15–20% for cutting waste (higher for intricate patterns).
- Choose thickness (20 mm is standard for backlit walls).
- Factor in finish and any bookmatching requirement.
Example: A 6 m × 3 m backlit wall = 18 sqm. With 18% waste = 21.24 sqm required. At AED 1,300/sqm = approximately AED 27,600 for material only.

Comparison with Marble and Other Natural Stones
Marble offers beauty but lacks translucency. Granite is stronger but opaque. Onyx uniquely combines luminosity, colour richness and workability. When properly supported and sealed, onyx performs reliably in both residential and commercial environments.
Maintenance, Sealing, and Long-Term Performance
Onyx is non-porous when correctly sealed. We recommend a high-quality penetrating sealer applied every 12–18 months in wet areas. Avoid abrasive cleaners and acidic substances. With proper care, an onyx installation will retain its colour and translucency for decades.
