Onyx marble is one of the rarest and most striking natural stones you can bring into a space. Formed slowly from mineral-rich water in caves, it carries flowing bands of colour and a natural translucency that no other marble matches. Because it can be lit from behind, onyx is the go-to stone for feature walls, reception desks, bar fronts and luxury interiors where the goal is to make a statement.
Onyx marble starts from βΉ150 per sq ft and goes up to βΉ900 per sq ft depending on colour, origin, slab quality and finish. Share your requirement for an exact quote.
Onyx is often grouped with marble, but geologically it is a banded variety of calcite formed in mineral springs and caves. Two qualities set it apart. First, its translucency β thin slabs let light pass through, which is why designers backlight it. Second, its dramatic veining β each slab is unique, and because onyx is book-matched (two slabs mirrored side by side), the patterns can be arranged into large symmetrical panels. It is a softer, more delicate stone than granite, so it rewards the right placement and the right care, both of which we cover below.
Onyx comes in a wide range of colours, each suited to different projects. Here is how our most requested varieties are typically used:
The most versatile option. Its pale base with gold and grey veining suits both classic and contemporary interiors, and it is the top choice for backlit walls because light spreads evenly through it. Commonly used for feature walls, vanity tops and reception cladding.
A rarer, higher-value stone with cool blue tones and river-like veining. Best reserved for statement pieces β a single backlit panel or a bar front β where its pattern can be shown off rather than repeated across a large area.
Warm, honey-toned and easy to work, which makes it popular for curved and custom shapes. It glows beautifully when lit and is widely used in hotel lobbies and restaurants to create a warm ambience.
Also called Lady Onyx, this variety shows pink and green veins over a soft white base. Designers use it where a gentle, decorative accent is wanted β powder rooms, dressing areas and boutique retail.
Rich green tones with a smooth, luxurious appearance. It has comparatively low water absorption, so it holds up better than most onyx in semi-outdoor and high-humidity settings when properly sealed.
Dramatic and exclusive, black onyx suits high-end, low-light spaces. It is commonly specified for bar tops, cladding and sink surrounds where a bold, moody finish is the aim.
The single most requested use of onyx is the backlit wall or counter, and it is where quality really matters. For an even glow, slabs are cut thin (around 10β20 mm), reinforced with a fibreglass backing, and lit with a diffused LED panel β not point lights, which create hot spots. We supply onyx selected specifically for translucency so the veining reads clearly when lit. If you are planning a backlit feature, tell us at the enquiry stage so we can pick blocks that transmit light well; not every slab is suited to it.
Being honest matters here: onyx is softer and more porous than granite, so it needs a little more attention. With the right care it lasts for decades.
Choose onyx when you want a translucent, backlit, one-of-a-kind feature and are happy to maintain a more delicate stone. Choose marble (or granite) when you need a harder, more forgiving surface for everyday floors and kitchen worktops. Many of our clients combine both β onyx for a hero feature wall and marble or granite for the surrounding practical surfaces. If you are unsure which fits your project and budget, our team can advise based on the exact space and traffic.

A few practical checks before you buy:
As a leading supplier, exporter and manufacturer of Indian marble, granite and onyx from Rajasthan, we hand-select every block and guide clients from slab selection through to installation advice. That end-to-end involvement is why architects and interior designers return to us project after project.
Onyx is available in several shades including white, yellow, green, pink, blue and black. White and yellow are the most requested because they light up beautifully when backlit.
Onyx is softer and more porous than granite, so it needs sealing and a little more care. Placed and maintained correctly β as a feature wall or low-traffic counter β it lasts for decades.
It can, with sealing and careful use, but it is best suited to low-traffic or accent counters rather than heavy-duty kitchen worktops. For busy kitchens we often recommend pairing an onyx feature with a granite work surface.
Onyx is rare, forms slowly, and yields fewer usable slabs per block than common marble. Premium imported onyx from Iran and Turkey commands the highest prices due to its colour and clarity; we help you find the best quality within your budget.
Yes β this is its signature use. It requires thin, translucent, fibreglass-backed slabs and diffused LED lighting for an even glow. Tell us at enquiry if you are planning a backlit feature so we select suitable slabs.
Unmatched visual impact, natural translucency for lighting effects, book-matched patterns, and genuine one-of-a-kind character that raises the perceived value of a space.
