Natural Marble · Travertine · Glass Diffuser

The Ostro Small Sconce pairs a solid stone body — marble or travertine, cut and polished from natural block — with a soft white glass diffuser. The silhouette is quiet and architectural: a rounded stone arc holding a single orb of light. Each piece carries its own natural veining, so no two sconces are ever quite the same — a small, honest luxury for hallways, bedsides, and powder rooms.

Styled view


Stone Colors — Choose at Checkout


Green

Deep green marble with pale mineral veining — moody and botanical.


Beige

Warm travertine with soft banding — the most versatile neutral.


Purple Red

Wine-toned marble with dramatic veining — a rich statement accent.


Purple

Cool lavender-grey stone — unexpected, subtle, quietly modern.

Natural stone varies. Each Ostro body is cut from natural marble or travertine — veining, banding, and tonal depth are unique to every piece. This variation is the character of the material, not a defect.

FAQ

Why does my sconce look different from the photos? +

The Ostro body is cut from natural marble or travertine, and no two blocks of stone are alike. Veining, banding, and tonal depth vary from piece to piece — this variation is the defining character of natural stone and makes each sconce one of a kind.

Which bulb do you recommend? +

A warm white (2700K) G9 LED bulb gives the most flattering glow through the white glass shade. Avoid cool-white or daylight bulbs, which produce a harsher tone against the stone.

Is the Ostro sconce dimmable? +

Yes — the sconce supports dimming when fitted with a dimmable G9 LED bulb and connected to a compatible dimmer switch. Standard (non-dimmable) G9 LEDs will work at full brightness only.

Where does this sconce work best? +

Its compact scale suits bedside walls, hallways, powder rooms, vanity surrounds, and reading nooks. It pairs beautifully in mirrored sets flanking a bed or a mirror — order two in the same stone color for a coordinated look.

How do I care for the stone body? +

Dust with a soft dry cloth. Avoid abrasive pads, acidic cleaners, and prolonged moisture, all of which can etch or dull the polished stone surface over time.

The Marble Series

Sculptural fixtures hewn from natural stone — each one carrying the signature of geology, time, and the human hand.

Born of Time

Pressure, heat, and one hundred million years — nature's slowest brushwork. Each lamp wears a pattern that exists once, and never again.

The Material

From Stone to Illumination

Marble is not a finish. It is a material with a memory.

A metamorphic rock, marble is born of recrystallized carbonate minerals — limestone subjected to heat and pressure deep within the earth's crust over geological time. Its distinctive veining, the subtle gradient of its color, the cool weight of its surface — all are records of the forces that shaped it across millions of years.

"Where a manufactured material repeats itself, marble can only be itself. Each piece is the only piece — the sole physical expression of a particular vein, formed once and quarried once."

Signatures of Stone

Three Marks of Authenticity

Three qualities you will only find in genuine, quarried marble — and never in anything cast, printed, or manufactured to imitate it.

i. Distinctive marble veining — every pattern unique
Vena

Distinctive Veining

Each vein traces the path of mineral seepage millions of years ago. Nature's own brushwork — a pattern that exists once, on this lamp, and nowhere else on earth.

ii. Subtle natural marble color variations — cream, ivory, pearl grey
Tono

Subtle Tonality

Cream, ivory and pearl grey deepen in soft gradients, occasionally crossed by veins of warm caramel. Quiet, natural tones that grace every interior style.

iii. The cool, smooth tactile quality of polished natural marble
Tatto

Cool, Tactile Hand

A density and coolness only ancient stone can offer. Marble holds the air around it — substantial, calming, real. A weight you feel before you see.

From Quarry to Hearth

Five Stages of Slow Craft

From the raw block extracted at the quarry, to the moment the lamp is wired and tested in our atelier — every fixture passes through five hand-guided stages.

N° 01 / Cava
Quarrying — solid blocks extracted from natural marble quarry

Quarrying

Solid blocks are extracted from the foothills, where geological forces left their finest seams. Only stones with sound structure and clean veining are selected.

N° 02 / Lastra
Slab cutting — diamond blade revealing marble veining

Slab Cutting

Diamond-tipped blades part the block into precise slabs — each cut is a first reveal of the unique veining hidden inside the stone for millennia.

N° 03 / Scolpire
Shaping and carving — skilled hand work on marble

Shaping & Carving

Each form is cut by skilled hands — a patient negotiation between the designer's intent and the grain of the stone itself.

N° 04 / Lucidare
Hollowing and polishing — interior bored, exterior honed

Hollow & Polish

The interior is bored to delicate walls so warm light may pass through. The exterior is honed and hand-polished to its final, luminous finish.

N° 05 / Montaggio
Assembly and wiring — final integration in the atelier

Assembly

Wiring, sockets and fittings are integrated by our atelier team. Each fixture is bench-tested and inspected before it leaves the workshop.

Measuring for Pendant Lighting

When installing pendants and chandeliers, it’s important to consider how you want your fixtures to hang in relation to the other furnishings in your space. Read on for our recommendations on how to hang the perfect light.

Kitchen

Aim for 30–36″ from the bottom of your fixture’s shade to the top of your island or countertop. Space multiple pendants 26–30″ apart. For a sense of proportion and balance, allow 12″ from the outermost fixture to the edge of your counter.

Dining Room

For optimal lighting and visibility, the bottom of your pendant should sit 30″ from the surface of your dining table. To scale your fixture, take the length and width of the room in feet, then convert that to inches. For a 10′ by 14′ room, the chandelier should be about 24″ wide.

Bedroom

If you’re hanging a pendant above a nightstand, allow for at least 30″ between the bottom of the shade and your nightstand’s surface. To keep the look balanced, center your pendant over your nightstand.
