Real vs. Fake Marble Lamps: How to Spot Genuine Natural Stone

Last month a customer sent us a photo of a lamp she'd bought somewhere else and asked, "Is this actually marble?" 

It's a fair question, and we get it a lot. Lamps sold as "marble" range from solid carved stone to plastic with a printed pattern, and online photos make them look nearly the same.

We've worked with natural stone since 2005, first at BSTSTONE and now through Marmor. So here's how we'd check a marble lamp before buying one.

Start with the veining

Real marble is messy. Veins wander off in odd directions, fade out, thicken, split in two. Nothing about it looks planned.

Fake marble tends to look too nice. The swirls are evenly spread, and sometimes you'll spot the same pattern on "different" lamps in the product photos. If you see that, it's a print.

Turn it over

This is the check I like best, because it's hard to fake. Look at the base and the edges. In real stone, the pattern goes all the way through, so you'll see veining on the underside and on any cut edge too.

If the pattern stops at the surface and the inside looks plain, hollow or painted, you've got a coating.

Pick it up

Marble is cool to the touch and heavier than you'd expect. When you first lift it, it should feel cold in your hand for a bit. Resin and plastic warm up almost instantly and feel light for their size.

If a "solid marble" lamp weighs about as much as a mug, I'd ask the seller some questions.

Switch it on in the dark

Here real stone shows itself. Light moves through marble unevenly, brighter where the stone is thin or pale and darker around dense veins. The glow follows the stone.

A fake often glows in one flat colour, or the pattern looks stuck on top of the light like a sticker.

I should be honest here, though. Real marble varies a lot in how much light gets through. Some pieces glow beautifully, others are dim. So a lamp that's softer than you hoped isn't necessarily fake. It might just be a denser piece of stone.

Read the listing like a skeptic

Watch the wording. "Marble-look," "marble-effect," "faux marble" and "marble pattern" all mean it's not marble. A seller using real stone will usually say "natural marble" outright and mention that every piece is different.

Also check whether there's an actual business behind it. Can you find an about page, an email address, a return policy? Someone who answers questions plainly is a good sign.

Please don't pour lemon juice on it

You'll see the "acid test" suggested online: drop a little vinegar or lemon on the marble and watch it react. It does work, since marble reacts with acid. But it can also leave a dull, etched spot on a polished surface, and then you've damaged the lamp you just bought. The checks above are enough.

What real marble is like to live with

Natural stone has quirks, and I'd rather you hear them from us.

Your lamp won't match the photo exactly. Colour and veining change from piece to piece. You might also see tiny pores or small marks, which are part of the stone. It needs gentle cleaning, because marble can stain and acids can etch it. And the glow varies, as I said above.

For most people that's the appeal. [Add one line in your own words about why you love working with natural stone.]

Where our Moon Lamp fits in

We built our Natural Marble Moon Ambient Lamp from real marble, so the veining belongs to the stone and no two lamps are the same. You can read more about us on the About Us page.

It's cordless, charges over Type-C, and runs up to 40 hours. A touch on top cycles through yellow, white and warm white, and holding it dims the light. There's a one-year warranty for defects, and 30-day returns on unused items in their original packaging.

And I'll say it plainly, as we do on the product page: it's a mood light. Because marble lets through different amounts of light, it isn't bright enough to read by. Think bedside glow, not desk lamp.

Looking after it

Wipe it with a soft cloth, dry or slightly damp, and skip acidic cleaners. Keep it away from heat and damp rooms. Charge it before the battery runs fully flat, and don't leave it lit for hours while it's plugged in.

Quick questions

Will my lamp look exactly like the photos?
 Close, but not identical. Natural stone varies, so yours will have its own veining.

Does real marble always feel cold?
 Usually, especially when you first touch it. Plastic and resin don't.

Is a marble-effect lamp a bad buy?
 Not if it's honestly described and priced for what it is. The problem is when it's sold as real stone.

Why is my marble lamp dimmer than I expected?
 Translucency differs from stone to stone. Marble lamps suit soft evening light better than bright light.
