Star Calacatta Honed Marble Mosaic Tile 13.75 x 12

Product Overview

Elysium Star Calacatta Honed 13.75" x 12" Marble Mosaic Tile combines the distinctive veining of Calacatta Gold with the crystalline purity of Greek Thassos White marble. Precision-cut stone pieces form an elegant interlocking star pattern that brings architectural rhythm and refined contrast to floors, backsplashes, shower walls, niches, and decorative features.

The soft honed finish gives the marble a smooth, low-sheen appearance while allowing its natural gray and warm-gold veining to remain visible. Crisp Thassos White elements brighten the pattern, while naturally varied Calacatta Gold pieces ensure that every sheet has its own character.

Part of Elysium’s Precious Stone Collection, this decorative mosaic works beautifully in classic, Mediterranean, Art Deco, transitional, and contemporary interiors.

Installation and Handling Guidelines

Important: White-Marble Installation Protocol

This mosaic contains light-colored natural marble. White setting materials, careful sealing, proper mortar coverage, and pre-installation blending are essential.

• Inspect and dry-lay all sheets before installation.

• Blend material from several cartons to distribute natural veining and tonal differences.

• Rotate and reposition sheets to prevent visible sheet outlines or repeated pattern sections.

• Use a premium white polymer-modified mortar approved for natural marble.

• Never use gray mortar, which may shadow through or discolor light-colored stone.

• Use a small-notched trowel appropriate for the mosaic thickness.

• Flatten prominent mortar ridges before placing the sheets.

• Use a grout float or padded beating block to embed each sheet evenly.

• Adjust individual pieces along sheet edges when necessary to maintain consistent pattern spacing.

• Achieve at least 95% mortar coverage in showers and other wet-area installations.

• Apply a penetrating natural-stone sealer before grouting.

• Use unsanded grout or a fine-aggregate grout specifically approved for honed marble.

• Test the grout and sealer on a spare sheet before applying them to the complete installation.

• Install shower applications over a complete waterproofing system. Sealer does not replace waterproofing.

• Include perimeter and movement joints according to TCNA EJ171 and applicable construction requirements.

• Wet-cut with a clean, continuous-rim diamond blade intended for marble.

• Order approximately 10–15% additional material for cuts, pattern matching, natural variation, and future repairs.

Grout Recommendations

• Bright White: Creates crisp contrast and emphasizes the star geometry.

• Warm White: Softens the pattern while complementing Calacatta Gold veining.

• Pale Gray: Adds stronger definition between individual marble pieces.

Dark or highly pigmented grout can stain light-colored marble. Always prepare and approve a grout test before installation.

Care and Maintenance

• Clean with warm water and a neutral-pH cleaner formulated for natural marble.

• Avoid vinegar, lemon, acidic bathroom cleaners, bleach, and abrasive powders.

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

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

• Do not use aggressive scrubbers that could scratch or dull the honed finish.

• Reseal periodically according to use, exposure, and the sealer manufacturer’s instructions.

• Use mats or protective pads in floor applications exposed to abrasive grit.

Frequently Asked Questions

Is this mosaic made entirely from Calacatta marble?

No. Elysium identifies the mosaic as a combination of Calacatta Gold marble and Greek Thassos White marble.

Is this genuine natural marble?

Yes. Both Calacatta Gold and Thassos White are genuine natural marble materials, so variations in color, veining, and mineral markings should be expected.

Does it require sealing?

Yes. Apply a penetrating natural-stone sealer before grouting and reseal periodically according to the installation environment.

Can it be installed on shower walls?

Yes. Install it over an approved waterproofing system using white mortar suitable for natural marble.

Can it be used on a shower floor?

The small mosaic pieces and numerous grout joints may provide additional traction, but no published DCOF value is available. Confirm suitability with the installer and applicable local requirements.

Will every sheet match exactly?

No. Calacatta Gold is naturally varied, and differences in veining, tone, and mineral markings are inherent characteristics of genuine marble.

What grout should be used?

Use unsanded grout or a fine-aggregate grout approved for honed marble. Always test the grout on a spare sheet before installation.
