Brass · Opal Glass Globe · Pebble Backplate
A wall sconce composed of two simple shapes — a pebble-form brass backplate and an opal glass globe set off-center against it. The asymmetry feels deliberate and quiet, like a stone resting against a wall with a moon balanced on top.
The opal glass diffuses the bulb into a soft, glare-free orb of light. Compact at just 14 × 20 cm — well-suited to bedside walls, beside mirrors, in hallways, or as a pair flanking a doorway.

FAQ
What bulb does it take? +
A single E26 (North America) or E27 (EU/UK/AU) bulb up to 25W. We recommend a warm white (3000K) LED in either G80 globe or standard A19 shape. Bulb is not included.
Can I mount it with the globe pointing down? +
Yes — the sconce can be installed in either orientation. Globe-up reads more like a rising-moon silhouette; globe-down reads more like a downlight. Both are correct installations.
Can I order it as a pair? +
Yes — this sconce is often installed in pairs flanking a mirror, doorway, or bed. Just order two units. For matched-batch finish consistency on larger orders, contact us first.
Is it dimmable? +
The fixture itself doesn't dim, but it becomes dimmable when paired with a dimmable LED bulb and a standard TRIAC wall dimmer (both sold separately).
Product features
Product features
- Hand-finished in natural materials — alabaster, marble, brass, and blown glass — so slight variation in veining, grain, or patina between pieces is normal and expected.
- Hardwired or plug-in per listing; check the individual product page for the exact wiring type and included cord length.
- Compatible with standard dimmer switches unless the listing notes otherwise.
- Bulb base type (e.g. E12, E26) is listed on each product page; bulbs are not included unless stated.
- Select pieces are made to order — see the product page for current lead time before ordering.
Materials and care
Materials and care
- Alabaster, marble & stone: dust with a soft, dry cloth. Avoid water and household cleaners — they can etch or stain natural stone.
- Brass & metal finishes: wipe with a dry microfiber cloth. Avoid abrasive cleaners, which will strip the patina.
- Fabric shades: spot clean only with a dry cloth.
- Glass: apply a mild glass cleaner to a soft cloth, not directly to the fixture.
- Always turn off and let the fixture cool before cleaning.
- Keep fixtures away from direct moisture unless the listing specifies it's rated for outdoor or wet locations.
Styling tips
Styling tips
- Wall sconces: mount at 60–66″ from the floor to the center of the fixture; space paired sconces 24–30″ apart.
- Pendants: hang 30–36″ above a table or counter surface, adjusting for ceiling height.
- Chandeliers: as a general sizing guide, allow roughly 2.5–3″ of fixture width for every foot of room width.
- Warmer bulb temperatures (2700K–3000K) bring out the tone in natural materials like alabaster and brass.
- Pairing with a dimmer switch gives you more control over ambiance in living and dining spaces.
