Product Overview
Green Onyx Penny Round Mosaic introduces luminous color, natural translucency, and classic geometric texture to interior walls and accent areas. Crafted from genuine green onyx natural stone, each sheet features 3/4-inch circular penny round chips displaying light to medium olive greens, pale mint, subtle rust-gold veining, and rich crystalline depth.
The smooth polished finish enhances the natural luster and light-reflective qualities of onyx, while the timeless penny round scale provides a soft, organic grid. Mounted on flexible mesh sheets, this tile simplifies installation across curved surfaces, feature walls, and decorative niches.

Installation and Handling Guidelines
-
Pre-Sealing Essential: Onyx is a porous, acid-sensitive natural stone. Test and apply a penetrating natural stone sealer on an uninstalled piece prior to grouting to prevent grout staining or haze.
-
White Mortar Required: Always use a premium white, polymer-modified thin-set mortar. Dark or gray mortars can show through translucent onyx chips and permanently discolor the stone.
-
Dry-Lay & Color Blending: Onyx exhibits significant natural variation in color intensity and veining. Dry-lay and blend sheets from multiple boxes before installation to achieve a balanced look.
-
Wet-Area Caution: Onyx can react to standing water and household chemicals. If installed in wet areas, ensure proper underlying waterproofing, appropriate slope, and a compatible stone sealer.
Care and Maintenance
-
Gentle Cleaning: Clean exclusively with warm water and a pH-neutral cleaner formulated for delicate natural stone. Never use vinegar, bleach, lemon juice, or abrasive scrubbing pads, which will etch and dull polished onyx.
-
Periodic Sealing: Reapply a quality penetrating stone sealer periodically based on surface exposure and usage.

Frequently Asked Questions
Is green onyx tile durable enough for heavy-traffic floor use?
Onyx is a softer, more delicate natural stone compared to granite or porcelain. It is primarily recommended for wall applications, accent backsplashes, and low-traffic decorative areas rather than high-traffic floors.
Does polished green onyx need to be sealed?
Yes. Sealing is strongly recommended to protect against moisture absorption and surface staining. Always test sealers on a spare tile first, as certain sealers may subtly alter the stone's color or clarity.
Why is white mortar necessary for installing onyx mosaic sheets?
Because onyx is naturally translucent, thinset color behind the tile impacts its final appearance. Gray mortar will make the green stone look dull and dark, whereas pure white mortar preserves its bright, luminous tones.
