Galaxy Black Marble

Galaxy Black Marble features a deep charcoal-black to almost black background with subtle dark green and grey undertones. Its sophisticated appearance is enhanced by flowing linear patterns, lighter greyish-brown and muted green streaks, and occasional tiny reflective mineral specks that create a starry-night effect. The overall appearance is dramatic, elegant, and distinctive, making it suitable for contemporary and luxury architectural designs.

Texture & Structure

Medium to fine-grained crystalline texture with prominent elongated mineral streaks and naturally layered structures. The surface displays parallel to slightly diagonal striations, irregular flowing bands, and occasional lighter mineral veins. Small reflective mineral inclusions contribute to its subtle shimmering effect. The stone generally has a compact, dense structure with natural variations in grain distribution and pattern continuity.

Usage

Suitable for interior flooring, wall cladding, decorative wall panels, bathroom vanities, countertops, reception desks, fireplace surrounds, staircases, columns, furniture tops, and ornamental architectural applications. Its dark background and distinctive linear patterns make it particularly attractive for feature walls, bookmatched installations, and high-end interior decoration.

Exterior applications may be considered depending on verified physical properties, local climate, installation conditions, and surface treatment.

Maintenance

Regular cleaning with a soft cloth, clean water, and a pH-neutral stone cleaner is recommended. Avoid acidic cleaners, vinegar, abrasive chemicals, and harsh cleaning products. Apply a suitable penetrating stone sealer to help reduce staining and moisture penetration. Periodic resealing may be necessary depending on usage and exposure. Clean spills promptly, particularly oils and acidic substances, to prevent staining or surface damage.
