Onyx Chrome is a black gel with a mirror buffed over it, so each nail turns into a dark pearl that reflects the room back in greys. It is chrome for people who find chrome too shiny: the black base takes the glare down and leaves the depth, and on a medium coffin it looks like polished stone rather than metal. Gunmetal by daylight, liquid by lamplight, and completely unbothered by a black outfit.
“Black gel base with mirror chrome powder buffed over for a dark gunmetal shine, glossy seal, medium coffin.”

How this look is done
- 01Shape to a medium coffin and apply a true black gel base in two thin coats, curing each.
- 02Apply a no-wipe top coat and cure briefly to create the tacky-free surface chrome needs.
- 03Buff silver or gunmetal chrome powder over the black until the surface turns to mirror, working right to the edges.
- 04Seal with a glossy gel top coat and cure so the reflection stays deep.
Who it suits
Every undertone — a black base is universally flattering — and it is spectacular on deep skin, where the mirror picks up warmth. Coffin, square and almond all work; longer shapes give the reflection more to do. It is an evening manicure that behaves in a conservative office.
How it wears
Two to three weeks in gel. Regrowth reads as a dark line rather than a bare gap, so black chrome ages better than pale mirrors. Keep the seal intact — a scratched top coat shows on a mirror far more than on a crème.
Softer or bolder
Softer: a charcoal base with a pearl chrome for a smoky, less reflective finish. Bolder: an oil-slick multichrome over the same black base, so the reflection shifts purple and green.
