Onyx composition is very similar to that of agate as both of these semi-precious stones are varieties of quartz. The difference lies in the pattern: onyx lines undulate in parallel across the slabs, whereas agate lines are circular. When the Greeks noticed that white onyx stripes resembled nails, they gave the stone its name, which in Greek means exactly that – nail.

The gemstone onyx is too expensive and is therefore used scarcely in interiors. Most often the walls and stairs are made of marble onyx which is softer than precious onyx and much more readily available. It is neither marble nor onyx, but resembles them both. Onyx marbles come in a variety of patterns and in soft, creamy colors. The most common onyx shades are green, yellow, pink and white.

One of the most attractive aesthetic properties of onyx is its ability to transmit light. Because of translucency, soft colours and bold patterns, onyx walls and counters acquire mysterious look when backlit. Artificial light sources are often installed to strengthen the effect. When combined with hidden strips of LED lights, this stone will make furniture and other elements glow.

Transparency is often the main reason why designers choose onyx over other stones for decoration. Onyx can be creatively used to make walls, partitions, bathroom vanities, window sills, stairs. Onyx looks original in luxury nightclubs and restaurants – you’ve probably seen onyx bars, decorative walls and washbasins lit up from the inside. Relatively thin and light, onyx panels are suitable for many interior design ideas.

The transparency of onyx slabs depends on their thickness and composition. Onyx sheets of 2-4 cm thick look great as furniture tops and worktops.
