3x6 Green Onyx Polished Subway Tiles

Product Overview

3" x 6" Green Onyx Polished Subway Tile showcases the remarkable color, translucency, and crystalline depth of genuine natural onyx. Its distinctive palette moves through emerald green, pistachio, olive, jade, cream, amber, and occasional rust-colored mineral accents.

The polished finish intensifies the stone’s natural banding and creates a luminous, jewel-like surface. Cut in a timeless 3" x 6" subway format, Green Onyx can be arranged in running bond, stacked, vertical, herringbone, or decorative border layouts. It is an expressive choice for backsplashes, bathroom walls, shower features, fireplace surrounds, bars, illuminated panels, and luxury commercial interiors.

Technical Specifications

Recommended Applications

• Kitchen Backsplashes: Creates a richly colored natural-stone focal point behind ranges, sinks, bars, and beverage stations.

• Bathroom and Vanity Walls: The polished surface reflects ambient light and gives compact bathrooms a luxurious appearance.

• Shower Walls and Niches: May be used over a complete waterproofing system with setting materials approved for moisture-sensitive onyx.

• Fireplace Surrounds: Adds natural color and movement around decorative fireplaces when installed within the fireplace manufacturer’s clearance requirements.

• Feature Walls: Suitable for reception areas, restaurants, boutiques, spas, private offices, and hospitality interiors.

• Decorative Borders: The 3" x 6" format works well as a framed accent, chair-height feature, or contrasting border.

• Backlit Installations: Green Onyx can transmit light beautifully, but successful backlighting requires a specialized translucent substrate, adhesive, and lighting system.

Installation and Handling Guidelines

⚠️ IMPORTANT: TRANSLUCENT AND MOISTURE-SENSITIVE ONYX

Green Onyx may darken, curl, shadow, stain, or discolor when installed with an unsuitable mortar. Test the complete installation system on spare material before beginning the project.

• Use White Setting Material: Never install light or translucent onyx with gray mortar. Use a premium white rapid-setting natural-stone mortar or epoxy adhesive approved for moisture-sensitive stone.

• Flatten Mortar Ridges: Trowel lines and inconsistent coverage may remain visible through translucent sections. Create a smooth, uniform setting bed before placing each tile.

• Dry-Lay Before Installation: Arrange tiles from several cartons to balance emerald, olive, cream, amber, and heavily banded pieces across the installation.

• White Backing: Any exposed or uneven backing color may affect the finished appearance. Backlighting and translucent installations require especially uniform preparation.

• Pre-Sealing: Apply a penetrating sealer approved for polished onyx before grouting. Test it on spare material to evaluate possible color changes.

• Grout Selection: Use unsanded grout or a fine-aggregate grout specifically approved for polished natural stone. Test before full installation to ensure it does not scratch or stain the surface.

• Grout Joint: A joint of approximately 1/16" to 1/8" may be appropriate, depending on tile calibration, layout, and installer recommendations.

• Wet-Area Preparation: Shower installations require complete waterproofing. Sealer protects the stone from staining but does not waterproof the wall assembly.

• Floor-Use Caution: Polished onyx is comparatively soft, scratch-sensitive, and slippery when wet. Limit floor use to approved low-traffic decorative areas and avoid shower floors.

• Cutting: Wet-cut with a sharp, continuous-rim diamond blade intended for delicate natural stone. Support the tile completely to reduce chipping.

• Order Allowance: Add approximately 10–15% for cuts, breakage, color blending, and future repairs. Herringbone and highly selective layouts may require additional material.

Backlighting Guidelines

• Standard mesh, gray mortar, trowel ridges, and opaque substrates can block transmitted light or create visible shadows.

• Use a uniformly illuminated translucent substrate and an adhesive approved for backlit onyx.

• Diffuse the lighting source to prevent bright spots, dark bands, and visible wiring.

• Build and approve a full-size mockup before completing the installation.

• Provide ventilation and future service access for the lighting components.

Care and Maintenance

• Clean with warm water and a neutral-pH cleaner formulated for onyx or delicate natural stone.

• Never use vinegar, lemon, acidic bathroom cleaners, bleach, or abrasive powders.

• Wipe spills promptly, especially oils, cosmetics, wine, coffee, citrus, and strongly pigmented liquids.

• Use microfiber cloths, soft sponges, or non-abrasive nylon brushes.

• Reapply a penetrating natural-stone sealer according to use, exposure, and the sealer manufacturer’s instructions.

• Protect the polished surface from sharp objects, heavy impacts, and abrasive cleaning tools.

Design Profile

• Aesthetic Inspiration: Art Deco glamour, biophilic luxury, Mediterranean interiors, jewel-box powder rooms, and boutique hospitality.

• Color Character: Emerald, jade, pistachio, olive, cream, honey, and occasional warm mineral accents.

• Visual Advantage: Natural translucency and polished crystalline movement give each tile unique depth.

• Layout Options: Running bond, stacked, vertically stacked, herringbone, basketweave-inspired arrangements, and decorative borders.

• Complementary Materials: Dark walnut, white oak, ivory limestone, Thassos marble, warm plaster, and smoked glass.

• Complementary Metals: Brushed brass, champagne bronze, antique gold, polished nickel, and matte black.

• Suggested Grout Colors: Warm ivory or pale beige creates a unified appearance, while soft gray provides stronger pattern definition.

Frequently Asked Questions

Is Green Onyx genuine natural stone?

Yes. It is genuine natural onyx with inherent differences in color, crystal structure, banding, and translucency.

Will every tile look the same?

No. Significant variation is expected. Some pieces may be predominantly green, while others contain cream, amber, olive, or darker mineral markings.

Does polished Green Onyx require sealing?

Yes. Apply a penetrating sealer approved for polished onyx before grouting and reseal periodically.

Can Green Onyx be installed on shower walls?

It may be installed on shower walls with a complete waterproofing system and setting materials approved for moisture-sensitive stone. A test installation is strongly recommended.

Can it be used on a shower floor?

Polished onyx is not recommended for shower floors because it is delicate and may become slippery when wet.

Can Green Onyx be backlit?

Yes, translucent areas can transmit light. However, an even result requires a purpose-built lighting system, translucent substrate, compatible adhesive, and approved mockup.

Why is white mortar required?

Gray or unevenly applied mortar may remain visible through translucent areas and can alter the stone’s finished color.
