If you have ever paid forty dollars for a "moonstone" bracelet and felt a small nag that something was off, you are not paranoid. The market is full of dyed howlite, pressed glass, and polymer beads sold as stone. Some sellers know. Most do not. Here is how to tell what you are holding before you spend another dollar.
A note on wellness: Crystals are part of a long tradition of symbolism and personal ritual. They are not medicine. Nothing here is medical advice, and no stone treats, cures, or replaces care from a qualified health professional. If you are struggling, please talk to a doctor or therapist.
The short version
- Turquoise is the most counterfeited stone in the bracelet market, and dyed howlite is usually what you are holding instead.
- Real stone is cool, dense, and slightly uneven, so identical saturated beads and round internal bubbles point straight at glass or resin.
- A ten dollar loupe plus a temperature check and an acetone swab will catch most common fakes at your kitchen table.
- Treated is not the same as fake, and a seller who names the treatment is doing the honest thing.
- If a listing will not name a country of origin, walk away and buy from a shop that will.

$9.95Why this matters, and why you should not panic
Counterfeit stones are not new. Egyptians faked lapis lazuli with blue faience four thousand years ago because the real thing was harder to come by than gold. Romans melted glass into "emeralds."
The good news: most stones sold by real shops are genuine. The trouble sits at the cheap end, in drop-shipped beads from anonymous suppliers and vague marketplace listings. Buy from a seller who names sources and posts close-up photos and you are usually fine. Buy a "raw moldavite pendant" for nine dollars with free shipping and you are buying bottle glass.
A fake can still be a real mineral. Most "imitation turquoise" is dyed howlite, and howlite is a genuine stone. It is just not turquoise.
Seven warning signs you are looking at a fake
Before you order a loupe or memorize the Mohs scale, run this list. Most fakes give themselves away long before any testing.
None of these alone proves a fake. Two or three stacked together usually does. Real crystals are messy: inclusions, color variation, small clouds, natural flaws.
Tilt both under a lamp and the difference shows in about two seconds: the shimmer on the left slides across the stone, the glow on the right sits still.
The crystals faked most often, and what they really are
Some stones get copied more than others, either because they are expensive or because they went viral.
Turquoise. The most counterfeited stone on the planet. Cheap "turquoise" is nearly always dyed howlite or magnesite, white minerals with gray veining that take blue dye beautifully. Real turquoise is uncommon and not cheap.
Lapis lazuli. Real lapis runs deep cobalt with brassy pyrite flecks and sometimes white calcite veining. Fakes are dyed howlite again, dyed jasper, or crushed lapis bound in resin. Pyrite should look like metal, not yellow paint.
Citrine. Roughly nine in ten "citrine" clusters are heated amethyst. Natural citrine is a pale, almost smoky champagne yellow. The bright reddish-orange cathedrals on Instagram are baked amethyst with a markup.
Malachite. Genuine malachite has concentric green banding no two stones share. The fake is poured polymer with the bands painted on, often too geometric.
Moldavite. Real moldavite is a tektite from a meteor impact fifteen million years ago, found only in the Czech Republic, and supply tightened sharply after 2021. Nearly every "moldavite" pendant under twenty dollars is bottle glass. The real thing has a wavy, wormlike surface and stretched bubbles, not tidy spheres.

Five tests you can run at home
You do not need a gem lab. A jeweler's loupe costs about ten dollars and the rest is already in your house. No single test is conclusive, so run two or three together.
Total cost of this setup is under twenty dollars, and the loupe does most of the work.
| 1 | The 10x loupe test. Hold the loupe close to your eye and bring the stone up to it under bright light. Look for air bubbles, swirl patterns, or color sitting on the surface instead of running through the stone. Bubbles mean glass. Surface-only color means dye. |
| 2 | The temperature test. Stone stays cold even after sitting on a desk. Glass and plastic warm almost instantly. Press the bead to your inner wrist. If it matches your skin in under five seconds, it is probably not stone. |
| 3 | The acetone swab test. Dip a cotton swab in nail polish remover and rub an inconspicuous spot. Color on the swab means dye. This catches fake lapis, fake turquoise, and dyed purple quartz sold as amethyst. |
| 4 | The weight check. Hold a stone you trust against one you do not, at roughly the same size. Stone is denser than glass and far denser than plastic. A piece that feels too light is suspect. |
| 5 | The scratch test, carefully. On the Mohs scale quartz is 7, glass sits near 5.5, plastic under 3. Try to scratch the back of a steel knife with the stone. Quartz will mark the steel. Glass will not. Only do this on a piece you can risk marking. |
One honest caveat. None of this catches lab-grown material, because lab-grown crystals are chemically identical to natural ones. Whether that bothers you is a separate question from dyed howlite pretending to be lapis.
The moonstone problem, and why opalite is not a stone
A large share of the "moonstone" jewelry online is opalite, some of it sold by people who do not know the difference.
Opalite is man-made glass, produced from the 1980s onward by mixing glass with metal additives for that milky glow. It also sells as "sea opal." It is pretty, it is about six dollars a strand wholesale, and it has no geological history at all.
Real moonstone is a feldspar. Its shimmer, called adularescence, comes from light bouncing between thin internal layers, so it travels across the stone as you tilt it. Hold real moonstone to a window and turn it: the blue moves. Turn opalite and the orange-purple glow stays put.

When "treated" is not the same as "fake"
Plenty of crystals on the market are real but altered.
|
90% Of citrine sold today is heat-treated amethyst. The change is permanent and the stone is still real quartz. It is simply not natural citrine. |
Most colored gemstones in commerce get treated somehow. Heat shifts color. Irradiation deepens blues. Stabilization fills cracks with resin so a soft stone can take a polish. Oiling brightens turquoise. Dyeing is the most aggressive of the bunch and the first to fade.
So the question is not whether a stone was treated. It is whether the seller says so. A good shop writes "heat-treated citrine" or "stabilized turquoise" in the listing. The ones who hide it are the ones to leave.
Four mistakes that make you an easy mark
MISTAKE 01
Buying from sellers with no source story.
Real shops can tell you where a stone came from. Afghanistan, Brazil, Madagascar, Arizona, the Czech Republic. A seller who will not name the country has told you something.
MISTAKE 02
Falling for the photo instead of the listing.
Marketplace images are color-boosted, smoothed, and sometimes generated outright. The bead that arrives will not look like the promo shot. Read the description and the reviews.
MISTAKE 03
Trusting a "certificate of authenticity."
A printed card with a seal the seller designed proves nothing. Real gem reports come from independent labs like the GIA, and they are used for fine gems, not bracelet beads.
MISTAKE 04
Never asking the seller a direct question.
Message them: is this dyed, heated, or stabilized, and where was it mined? An honest seller answers specifically. A reseller of mystery beads dodges or goes quiet. The reaction is the test.
What to do if you already bought a fake
Do not throw it out. If the stone was misrepresented you may have a refund coming, so save the listing, the receipt, and your test results, then contact the seller in writing. Most platforms side with a buyer who brings evidence.
Do not be embarrassed either. The first lapis bracelet I owned was probably dyed jasper, and it taught me more than the real one did. If the piece turns out to be genuine but mislabeled, howlite sold as turquoise or opalite sold as moonstone, keep wearing it for what it actually is. Howlite carries its own symbolism in crystal tradition, and plenty of people wear opalite simply because they like it.
For the next purchase, stick with shops that name sources and answer questions plainly. Our crystal bracelet collection lists origin and treatment on every piece, and the guide on how to choose the right crystal bracelet covers what to look for in a listing.
Frequently asked questions
What is the most commonly faked crystal?
Turquoise, by a long margin. Most "turquoise" sold under twenty dollars is dyed howlite or dyed magnesite. Lapis lazuli, moonstone, citrine, and moldavite are the other heavily counterfeited stones in the consumer market.
How can I tell if a moonstone is real?
Tilt it under a light. Real moonstone shows a soft blue or white adularescence that moves as the stone turns, over a cloudy translucent body. Opalite has a flat orange-purple glow that looks the same from every angle. Opalite is man-made glass, not moonstone.
Does heated or treated mean fake?
No. Heat-treated citrine is still real quartz, and stabilized turquoise is still turquoise, just resin-filled so it can be cut and polished. Treatment is normal in the trade. The problem is a seller who hides it.
Is lab-grown the same as fake?
No, and the difference matters. Lab-grown amethyst is chemically and structurally identical to natural amethyst, so it is real amethyst grown in a controlled environment. Dyed howlite called turquoise is not turquoise at all. Mislabeling is the actual problem, not synthesis.
