Nero Portoro is quarried at Portovenere in Liguria and has been celebrated since Roman times as one of Italy's most prestigious black marbles. Its deep black surface is threaded with gold and white veining, and no two slabs are alike, which makes every piece in this collection a genuinely one-of-a-kind object.
The stone that has to be read before it is cut
Portoro has always been treated as a precious material rather than a building one, and the reason is in the veining. The gold runs in defined bands, so a block has to be read and cut along the direction of those bands rather than simply sliced. Get it wrong and the pattern breaks across a face. It is the slowest marble we work and the least forgiving, which is why it sits at the top of the Diamond collection.
The system inside
Boveda packs supply the moisture, releasing it when the interior dries and reabsorbing it when the level climbs, and a dynamic dual-fan system circulates that humidity through the cabinet so the far end holds the same level as the packs themselves. There is no distilled water and no sponge: the packs are replaced when they begin to stiffen, typically every two to four months. Internal ambient LED lighting makes the gold veining read properly, which in a stone this dark it otherwise would not. The humidor opens on a solid oak drawer with a Blumotion soft-close mechanism rather than a lid, so opening it does not release the conditioned air in a single movement.
Capacity and care
The 120-cigar capacity is measured on a standard Toro, around 135 Robusto, and varies with ring gauge. Keep the humidor below roughly 21 °C and out of direct sun. Above about 24 °C tobacco beetle eggs can hatch inside a cigar. Clean the marble with a soft, barely damp cloth only: acidic and limescale products etch polished stone permanently, and on Portoro the damage shows most on the gold.

Nero Portoro: A Rare and Difficult Beauty
Nero Portoro is one of the rarest black marbles in the world, quarried at a single, limited site near Portovenere, on the Ligurian coast of Italy. Its deep black background, threaded with veins of gold and white, has made it one of the most coveted stones since Roman times, reserved historically for the most prestigious architecture and the finest craftsmanship.
That same veining, the very source of its beauty, is also what makes Nero Portoro notoriously difficult to work with. The marble tends to fracture precisely along its veins, turning every cut, polish, and finish into a delicate operation that leaves little room for error and results in a very low yield from each block extracted.
For this reason, every surface of this humidor is polished entirely by hand, and every component is hand-assembled, piece by piece, inside our own Italian laboratories. Nothing is outsourced. The result is a genuinely one-of-a-kind object: rare, delicate, and refined in a way that only a fully handmade process can achieve.
Silence, by Design: Our Patented Humidification System
Preserving a fine cigar collection has always meant vigilance: checking humidity levels, refilling water, guessing when to intervene. We engineered a system that removes all of it. Our patented humidification technology works in near-total silence, quietly circulating air through the humidor without ever asking for your attention.
At its core is a set of silent fans that activate automatically, drawing on the Boveda system to distribute humidity evenly across every corner of the interior: no dry pockets, no manual adjustment, no guesswork. Everything happens on its own, exactly when it's needed.
No batteries to replace. No distilled water to pour. No maintenance routine to remember. It is, quite simply, a climate system that disappears into the background, so the only thing you ever have to think about is your cigars.
- Fully automatic activation: no switches, no timers to set
- Boveda-powered, for consistent, even humidity throughout
- No batteries required
- No distilled water refills: zero maintenance
- Engineered and patented exclusively for the Diamond Collection
