Gelso Onyx White Sconce

The piece

Natural Onyx · Glass Globe · One-of-a-Kind Veining

A wall sconce shaped from real natural onyx — every piece carries its own veining, tonal gradient, and quiet character. The curved onyx backplate cradles a soft glass globe, casting light that pools and layers across the stone's surface. Each Orli is genuinely one-of-a-kind: when you order, we hand-pick from currently available stones and confirm with you before shipping.

Product overview

How It Works — Universal SKU Stone Selection

Why a Universal SKU? Because each piece of natural onyx is unique, listing every individual stone would mean constant "out of stock" notices. Instead, your order reserves a fixture — and we email you with the actual stones currently available so you can choose your favourite before we ship.

Step 01

Place Your Order

Order the Universal SKU at checkout. Add a note if you have a preference — lighter / darker / more veining / less veining.

Step 02

We Email You

Within 1 business day, you'll receive photos of currently available onyx stones to choose from.

Step 03

You Confirm

Reply with your preferred stone. No rush — we'll wait for your selection before preparing the order.

Step 04

We Ship

Once confirmed, we begin final preparation and ship the exact piece you selected.

FAQ

Why don't I receive my order immediately? +

Because every piece of onyx is genuinely unique, we want you to see and choose the exact stone before we ship. Within 1 business day of your order, you'll receive an email with photos of currently available onyx pieces. Once you confirm your favourite, we begin final preparation and ship — usually within 2–3 business days of your confirmation.

What if I don't like any of the stones you send me? +

Let us know — we'll show you the next available batch as new stones come in, or process a full refund if you prefer. Your order is not finalised until you confirm your stone choice, so there's no risk in placing a Universal SKU order.

Can I request specific veining or colour? +

Yes. Add a note at checkout describing your preference: "more veining", "as little veining as possible", "lighter tone", "darker tone", or "more translucent". We'll do our best to match your preference from current stock when we send the photo selection.

Is this real onyx or a stone-look composite? +

It is real natural white onyx — quarried, hand-cut, and finished from genuine stone. The veining, slight translucency when lit, and tonal subtlety cannot be reproduced by composite or printed materials. The cut and finishing is done by hand, which is why each piece is one-of-a-kind.

Which bulb do you recommend? +

A G9 LED bulb in warm white (2700K), at 3–4W. The warm light brings out the natural translucency of the onyx and softens the glass globe's diffusion. Avoid cool-white or daylight bulbs — they fight the natural warmth of the stone.

Is the lamp dimmable? +

Yes — paired with a dimmable G9 LED bulb and a TRIAC-compatible wall dimmer (e.g. Lutron Skylark, Leviton Decora), the Orli dims smoothly. Dimmed light is particularly atmospheric — the warm glow accentuates the stone's veining as it transitions from bright to soft.

Can I see other Gelso wall lamps in this series? +

Yes — the Gelso series includes additional sconce shapes and configurations using the same natural-stone aesthetic. Browse the full series here →

How do I clean natural onyx? +

Switch off the wall power and let the bulb cool. Dust with a soft dry cloth. For deeper cleaning, wipe with a soft cloth lightly dampened with water and a drop of pH-neutral mild soap. Avoid acidic cleaners (vinegar, lemon, citrus-based products) which can etch natural stone. Do not use abrasive sponges or polishing compounds.

What if the onyx arrives chipped or cracked? +

Natural stone is carefully packaged but can occasionally be damaged in transit. If your sconce arrives chipped or cracked, please contact us within 48 hours of delivery with photos — we will arrange a replacement promptly. Do not install a damaged piece.

Care & delivery

Looking after it

Dust with a soft dry cloth. Stone, plated and painted finishes dislike solvents and abrasives, so keep both away from them; glass takes a lint-free cloth and a little glass cleaner. Solid brass is left unlacquered on most pieces and will warm and darken with handling, which is the material behaving as it should rather than a fault. Switch a fixture off and let it cool before cleaning it.

Who makes it

This piece is manufactured for Elio Marchetti by Radilum, our production partner for the collection.

We are a lighting house rather than a factory. We select the pieces, specify the finishes and the stone, and hold the relationship with the maker, and we would rather tell you that plainly than leave it unsaid. Questions about the manufacture of a specific fixture are welcome and we will answer them.

Delivery

Allow 28 to 43 business days from order to arrival, roughly six to nine weeks. Most of the collection is made to order, so that time covers the piece being built in the finish and size you chose, checked, packed and shipped. The same window applies wherever you are.

Shipping is free to Canada, the United States, the United Kingdom and Australia, with no minimum order.

Returns

You have ten days from receiving a piece to have it on its way back to us, under way inside those ten days rather than simply flagged with us on the tenth. Return postage on a change of mind is yours, there is no restocking fee, and the outcome is a refund to your original payment method rather than store credit. Made to order pieces return on the same terms as stock. Contact us before sending anything back.

Damaged or faulty on arrival

Separate from an ordinary return, and a longer window: twenty days from receipt to report it. Tell us before you send anything, keep the packaging until we have answered, and photographs of both the fault and the box help. Where a piece is faulty, damaged in transit or not what you ordered, we cover the return postage.

Installation

Any hardwired fixture should go in with a licensed electrician. Where a piece has particular requirements, a sloped ceiling, a chain that can be shortened, a specific socket, they are listed further up this page.
