Deep Sea Black Onyx

Deep Sea Black Onyx features a distinctive combination of muted greyish-green, sage and olive tones, creamy beige bands, and sharply contrasting reddish-brown, copper and dark amber veins. Despite its name, the stone is not uniformly black; its appearance is defined by layered oceanic depth and rich natural color variations. The interplay of earthy tones creates a dramatic yet elegant decorative surface. Its natural translucency allows light to pass through selected areas, enhancing the depth and character of the stone.

Texture & Structure

The stone displays prominent horizontal and undulating stratified layers with a fibrous, crystalline structure characteristic of decorative onyx. Wavy, ribbon-like contours run across the surface, creating flowing patterns and a sense of movement. Natural fissures, darker mineral-filled lines and localized crystalline clusters add further visual complexity. The surface can be polished to a smooth finish, although fine polishing marks and natural structural features may remain visible.

Pattern & Veining

• Pattern: Distinctive horizontal, wavy and layered formations.

• Veining: Irregular reddish-brown, copper and dark amber veins intersect the greyish-green and creamy beige bands.

• Texture: Fine-grained to crystalline, with fibrous and locally translucent areas.

• Variation: Each slab may display different band widths, color distribution, vein density and crystalline formations. Bookmatching can create striking symmetrical patterns.

Technical Characteristics

The following figures are indicative estimates for preliminary database reference only. They are not certified test results for this specific quarry material.

Chemical & Mineralogical Composition

Indicative composition by weight; actual mineral proportions and chemistry require laboratory analysis.

The stone is expected to be predominantly calcite-based, with possible aragonite and minor mineral impurities contributing to its coloration and crystalline features. The reddish-brown and amber tones may be associated with iron-bearing minerals.

Usage

Deep Sea Black Onyx is primarily suitable for decorative and interior architectural applications, including:

• Feature walls and decorative wall panels

• Backlit wall installations and illuminated partitions

• Luxury bathroom walls and vanity surrounds

• Reception desks and decorative furniture

• Fireplace surrounds in suitable low-heat applications

• Decorative tabletops and countertops with appropriate protection

• Bookmatched feature installations and bespoke interior designs

Maintenance

Deep Sea Black Onyx is relatively soft and sensitive to acids, scratching and impact. Use pH-neutral stone cleaners and a soft cloth for routine cleaning. Avoid vinegar, lemon juice, acidic detergents, abrasive pads and harsh chemicals. Apply a suitable penetrating sealer to reduce staining, following the manufacturer's recommendations. Because of its natural fissures and crystalline structure, careful handling, professional installation and appropriate reinforcement are recommended. For countertops and other frequently used surfaces, use protective coatings and avoid direct contact with hot cookware.
