Onyx by Emil

Collection Summary

Onyx by Emil is a porcelain stoneware collection from Emilceramica, marketed by the manufacturer as Tele di Marmo Onyx. It reproduces onyx by layering the stone’s shade variations and transparencies beneath the surface, which gives the tile visual depth and an inner glow.

Tile X Design offers five colors: Ivory, Pink, Green, Blue and Black. Formats range from a 47×109 (120×278 cm) slab to 1×1 and 2×2 mosaics and an Intrecci decor. SilkTech versions add slip resistance while keeping a silky feel.

Design & Aesthetic

Each Onyx colorway has a distinct character, according to Emilceramica’s catalog:

• Ivory moves through subtle shifts between white and ivory.
• Pink ranges from white to blush, with deeper coral layers showing through.
• Green sets lighter shading against a green ground, with large mineral inserts whose crystals run from ice grey to rust.
• Blue spreads around a pale blue center, with light and dark tones suggesting stratified layers.
• Black reads as near-absolute black, with pearl, ivory and rust veining surfacing through it.

The catalog frequently pairs Black with lighter tones, and Green with Ivory. This supports two-tone schemes as well as single-color rooms.

Design Applications

Emilceramica shows Onyx on floors and walls in bathrooms, kitchens, living rooms, bedrooms, boutiques and offices. Its intended-use ratings are heavy commercial, plus light commercial for Full Lappato. Useful scenarios include:

• Statement surfaces: full-height 47×109 slabs in hospitality or retail settings.
• Mixed-finish floors: Silk-finish 24×47 or 12×24 where slip resistance is needed, coordinated with Glossy walls in the same color.
• Detail areas: 1×1 and 2×2 mosaics and Intrecci that extend the palette into smaller zones.

Specifying Onyx

• Thickness varies. The 47×109 and 47×47 slabs are 6.5 mm. The manufacturer lists 36×36, 24×47 and 12×24 at 9.5 mm.
• Finish by format. The 47×109, 47×47 and 36×36 are Glossy only on TXD. The 24×47, 12×24, Intrecci and mosaics come in Glossy or Silk (SilkTech).
• Mosaic sizes are nominal. The 1×1 corresponds to Emilceramica’s 3×3 cm mosaic and the 2×2 to its 5×5 cm mosaic.
• Plan slab layouts. The 47×109 is produced in 6 faces per color, and the 12×24 runs 52–56 faces. Review faces when planning large walls.
• Joints and variation. A 2 mm grout joint is recommended, and shade variation is rated V3 (High).
• Newer colors. Emilceramica has added Stormy Day and Stormy Night, which are not currently listed at Tile X Design.

Frequently Asked Questions

Should Glossy or Silk be specified for Onyx floors?

Silk (SilkTech) is Emilgroup’s slip-resistant surface, designed to keep its slip performance without a surface treatment. Glossy is a polished finish. Where floor slip resistance matters, specify Silk and confirm values against project requirements.

Can different Onyx colors be combined?

Yes. Emilceramica’s catalog repeatedly pairs colors, such as Black with Ivory or Pink, and Green with Ivory. Pairing a dark and a light tone is a common way to use the collection.

What should be considered when using Onyx slabs on a feature wall?

The 47×109 slab is 6.5 mm thick and comes in 6 faces per color. Review faces or a dry layout in advance, and confirm substrate and handling requirements for thin large-format material.

What is the difference between the Onyx mosaic options?

The 1×1 and 2×2 mosaics use different chip sizes in the same palette. Intrecci is a woven-pattern decor. All three are offered in Glossy and Silk.
