Portoro marble
Marble · Italy
Black fragments wrapped in a web of gold and white veins: that is Portoro, an Italian marble of high contrast. It shines in pieces you look at head on: a bathroom wall, a dining table or the front of a bar.

What Portoro marble looks like
The background is black, crossed by a dense web of gold and white veins that leaves the background's own fragments separated from each other: the pattern is brecciated and high contrast. Dark brown also appears within the web. The photo shows it polished: that shine gives the gold all the attention. The variation of this slab is moderate: the gold and white web carries the whole pattern.

- TablesDining rooms and centerpieces; wine always on coasters
- KitchenThe kitchen suits it if you accept its wear marks over the years
- OutdoorsLittle: the weather takes down the shine; better with a matte finish

When the project has several pieces, ask for a photo of each slab: each one lays out the web in its own way.
Portoro Marble Finishes
The photo shows a polished finish; the other finishes lower the gloss and change what you see against the black.
-
Polished
The gloss in the photo: it deepens the black and brightens the gold of the web. Wet, it slips on a bathroom or shower floor.
-
Honed
No mirror gloss. Wet, it slips less than polished: it suits bathroom floors and showers.
-
Brushed
It shares the bathroom and shower spot with honed: both replace polished where the floor gets wet.

Questions about Portoro marble
How is Portoro different from Nero Marquina?
Two blacks with different characters. Nero Marquina keeps a deep black with almost no veins: the few it has are white, thin and straight; Portoro, instead, spreads a gold and white web across the whole slab. One complements; the other fills the wall.
Does Portoro work in a kitchen used every day?
It works under one agreement: the years will leave a patina of use. Lemon or vinegar opens a matte patch in the shine; it is a chemical reaction, not a stain. Those patches also recover with a pass of polishing. If you want a countertop that keeps its look over the years, granite stands up better to acids.
How do you care for Portoro?
On such a dark background, water marks and dust give themselves away sooner than on a light marble: when you clean it, finish with a dry cloth. Water with neutral soap is enough. If an acidic liquid spills, dry it as soon as it lands. You repeat the sealer depending on what the stone absorbs; check it with a drop of water.
Portoro or Grand Antique: how do I tell them apart?
Both carry fragments, but spread differently. In Grand Antique, the zone of broken white fragments takes one side of the slab and the rest stays intense black; in Portoro, the gold and white web wraps the fragments across the whole surface. Ask for a full photo of each slab before you decide.
Can I receive Portoro in my country?
Before you buy, we send you photos of the slabs available for your order. We ship to any country, with the stone's documents of origin and its CE certification. On the shipping page we explain how it reaches each region.
