Black Banded Onyx

Black Banded Onyx from Pakistan

Black Banded Onyx is a layered calcite mineral formed by the slow, rhythmic deposition of mineral-rich water in underground cavities over geological time. Each band represents a separate phase of mineral precipitation, with alternating layers of black (carbon and manganese-rich calcite) and white to cream (pure calcite) building up to create the stone’s signature striped appearance. The banding direction, thickness, and contrast vary naturally across the block, making each slab a unique natural pattern. Pakistan’s onyx deposits are world-renowned for producing banded varieties with exceptional clarity, contrast, and translucency.

Available Forms

• Raw Blocks: quarry-extracted, for processing at the importer’s facility

• Slabs: cut to standard or custom dimensions, 15-20 mm for backlighting, 20-30 mm for standard use

• Tiles: 30x30, 60x60, 120x60 cm and custom formats

• Backlit panels: slabs cut to 10-15 mm for maximum light transmission, with mesh backing

• Custom shapes: circular, oval, curved, and bookmatched pairs

Surface Finishes

Polished, Honed, Brushed. Polished finish intensifies the black-and-white contrast and maximizes translucency.

Industrial Uses

• Backlit feature walls: Black Banded Onyx panels over LED light boxes create a dramatic glowing effect where the white bands transmit light and the black bands remain opaque, producing a striking light-and-shadow pattern. This is one of the most visually impactful backlit stone applications available

• Luxury feature walls (non-backlit): Large-format polished slabs as statement walls in hotel lobbies, penthouse interiors, corporate boardrooms, and high-end retail spaces

• Bar and reception counters: Backlit or standard-lit Black Banded Onyx countertops and fascia panels for five-star hotels, premium bars, and corporate reception desks

• Bathroom and spa interiors: Full-height wall cladding, shower enclosures, vanity surfaces, and bathtub surrounds in luxury bathrooms. The black and white banding complements both modern monochrome and classic interior schemes

• Elevator and lift interiors: Backlit or polished panels for elevator cabs in luxury towers and hotels

• Flooring: Polished tiles in low-traffic luxury areas such as master suites, private lounges, and VIP rooms

• Furniture and decorative objects: Tabletops, console surfaces, lamp bases, bowls, bookends, and decorative accessories. Black Banded Onyx is particularly popular for luxury home accessories

• Architectural accents: Column cladding, fireplace surrounds, staircase handrail panels, and window sill capping
