Onyx panels, specified by the numbers

Onyx bonded to a translucent honeycomb core or to laminated glass, depending on what the assembly needs. Panel data, stone availability and attachment options — the things a specification actually turns on.

3–4

lbs/ft² honeycomb

5mm

stone thickness

8.5–9.5

lbs/ft² glass-backed

filled faults accepted

Two panel builds

Which one you specify depends on whether the panel needs a glass substrate. Both take the same stone.

FT-20 · translucent honeycomb

Honeycomb-backed

The core carries the load and diffuses the light, so a large face lights evenly with no source visible through the stone. The lighter of the two, and the usual choice for vertical feature work.

Buildup: 5mm stone + 20mm translucent fiberglass honeycomb
Weight: 3–4 lbs/ft²
Attachment: Mechanical
Reinforcement: None required behind the panel

DS-10 · laminated glass

Glass-backed

For assemblies that call for a glass substrate — structural glazing, tempered or blast-resistant applications. Heavier, and specified where the glass itself is doing a job.

Buildup: 5mm stone + 10mm laminated glass
Weight: 8.5–9.5 lbs/ft²
Attachment: Mechanical
Suited to: Backlit panels requiring a glass substrate

Stone availability

Onyx first, then the translucent quartzites and semi-precious materials. Availability is block-dependent, so treat this as a starting list rather than a catalogue.

Material	Character lit	Typical use
Honey onyx	Warm, holds colour at low output	Feature walls, bar fronts, reception
White onyx	Cool and even; veining reads as line work	Vanities, vitrines, ceilings
Green onyx	Deep, saturated; needs more output	Feature panels, casework
Oro onyx	Gold movement, high contrast	Statement walls, hospitality
Vein-cut onyx	Horizontal banding rather than cloud	Long runs, banding, architectural
Agate	Cellular, high variation piece to piece	Small panels, displays, vitrines
Translucent quartzite	Crystalline; brightest of the group	Counters, islands, feature walls
Semi-precious	Composed rather than slabbed	Displays, tops, small features

Selected at the block

Onyx does not reveal its character until a block is opened. Selecting at that stage — rather than buying finished slabs — is what makes a consistent run possible across a wall, and it is the only point at which faults can be avoided rather than disguised.

It matters more for onyx than for any other stone, because everything is going to be lit. A repair invisible in a yard becomes the most visible thing on the wall.

Fissure-free cutting where the piece requires it, rather than fissures filled and finished over.
No discoloured epoxy. Standard practice in the slab market; unacceptable in material that will be lit.
Pantone range matching for budgeted work, so specified colour is delivered colour.
Exact matching sourced where a brand or an existing interior sets the target.
