Real vs Fake Pixiu Bracelet: 5 Tests Anyone Can Do at Home
Most fake Pixiu bracelets do not announce themselves. Black glass, dyed resin and polymer-filled jade are designed to pass in photographs, and at arm's length they usually do. The checks that work are the ones aimed at properties a mould cannot copy: how the material behaves in light, what sits inside it, how it feels in the hand, how the carving was cut, and what the metal parts are made of.
These are five tests you can run at a kitchen table. They will not turn you into a gemmologist, and they cannot certify a stone, but they will catch the great majority of pieces sold as something they are not. The material notes and the buying advice come after the tests.
The tests below are easier to run against a known reference, so if you want something to compare with, the Pixiu jewelry page puts the bracelets, pendants and rings side by side.
The tests below work on any strand; if you want a reference piece to compare against, the Pixiu bracelet page shows bracelets with visible bead-to-bead variation.
The obsidian entry describes volcanic glass and its conchoidal fracture, which is the reason a chipped edge looks sharper than it feels.
Five tests you can run at home
1. Shine a light through the bead
Work in a dark room and press a phone torch flat against one side of a bead. Look at the other side, not at the glare on the surface. Natural black obsidian is effectively opaque; at most, the thinnest edge may show a faint brown or green glint. Black glass often glows evenly, and dyed glass can show colour where the dye pooled. A bead that lights up like a lamp is not obsidian.
The test reads differently on other materials. Jade is translucent, but the light should look diffuse and fibrous, like light through a thin slice of soap; glass imitations transmit cleanly. Tiger eye is opaque, with only the chatoyant band moving across the surface. A gold bead is metal, so any glow from inside means a coated core or plastic.
2. Look for bubbles, swirls and injected filler
Use a jeweller's loupe or a phone macro. Round, perfectly spherical bubbles are the signature of cast glass or resin; they do not form in volcanic glass. Swirl marks and flow lines also belong to moulded material. A seam around the widest point of a bead is a mould seam.
Jade has its own version of this problem. Polymer-impregnated jade, usually sold as Type B, is real stone that has been bleached and filled to hide cracks. It looks unnaturally even and glassy, and a UV torch may show blue-white fluorescence from the polymer. That is an indicator rather than proof, because some untreated stones also react, but a uniformly glowing strand at a low price deserves a second look. Never heat or scratch a bead to test it.
3. Weigh it and feel it
Plastic and resin are unmistakably light. A stone bracelet has heft, and a strand that feels hollow is not stone at all. Beyond that, weight is a coarse filter: obsidian and ordinary black glass sit at almost the same density, so a glass fake can feel exactly as solid as the real thing.
Relative weight is more useful across materials. Nephrite jade feels noticeably heavier than obsidian of the same bead size, and jadeite heavier still; tiger eye sits in between. Coolness is not a test, because glass and stone both feel cool and warm at similar rates. Compare every bead instead: real stone varies slightly in tone, size and surface, while moulded beads are identical twins.
4. Read the carving
A carved Pixiu should have crisp undercuts where the mane meets the neck, distinct teeth, defined nostrils and claws that separate from the body. Look for tool marks and small asymmetries; hand-finished work is rarely perfect. Moulded copies lose the deepest undercuts, have softly rounded edges and repeat the same painted shading in every recess.
Carving quality is not proof of material, but the two usually travel together. A maker who pays for real stone and hand work rarely mounts it on identical glass beads.
5. Inspect the metal and the plating
The Pixiu charm, spacers and clasp are where the cheapest substitutions hide. Hold a magnet against the charm; brass, copper, silver and stainless steel are not magnetic, so a charm that sticks contains iron. Look at the join where the loop meets the body: a plated piece often shows a different colour or a seam, while solid metal is one colour throughout.
Plating is not automatically a fake. Gold-plated, gold-filled and vermeil pieces are legitimate when the seller says so. The problem is a plated charm sold at a solid-metal price, or a gold bracelet whose plating wears through in a month. Read the words carefully: gold plated and gold are different claims. A green or grey mark on your wrist comes from the metal, not the stone.
The Mohs scale entry gives the hardness comparisons used below; a fingernail sits at about 2.5.
What changes by material
Black obsidian
Obsidian is volcanic glass, rated 5 to 5.5 on the Mohs scale. Natural pieces can contain mineral specks and tiny cristobalite patches, but not round air bubbles. A fingernail will not scratch it, though steel and quartz will. Gold sheen and silver sheen obsidian carry a natural directional flash from microscopic inclusions; that flash should move with the light rather than sit on the surface like paint. The common fake is uniform black glass with bubbles and identical beads. A black obsidian and tiger eye bracelet shows the natural bead-to-bead variation to look for.
Jade
Jade is either nephrite or jadeite, and both are often treated. Type A means untreated and waxed only; Type B is bleached and polymer-filled; Type C is dyed. Under a loupe, dye collects in cracks, while polymer filling creates an unnaturally glassy surface over what should be a waxy stone. Ask the seller to state natural Type A in writing and to provide a laboratory report with a checkable number. The carved Hetian jade Pixiu bracelet is a useful reference for the waxy luster of nephrite.
Tiger eye
Tiger eye is a fibrous quartz with a chatoyant band that must move as you tilt the bead. A painted stripe stays put, and a dyed stone shows colour concentrated in surface cracks. Under a loupe the fibres should look like fine parallel hairs. At 6.5 to 7 on the Mohs scale it is harder than obsidian or jade, and it will scratch ordinary glass, but so will quartz imitations, so treat that as supporting evidence.
Gold
Solid gold is dense for its size and carries a hallmark such as 18K, 14K or 999. Gold-filled and vermeil pieces have a thicker layer than plating, but they are still not solid. The quickest checks are the magnet, the colour at wear points, and the weight. Plating wears first at the high points of the carving, which is where a seller's close-up photograph should be sharpest. Prices help set expectations: in this collection a gold-plated red-string style is listed at $53.59, while a 999 gold and cinnabar bracelet is $492.59.
When the stone and metal checks are done, the next question is how the piece will be worn. Our guide to choosing a Pixiu bracelet by material compares all five options, and the care guide explains what each needs afterward.
Tests that do not settle anything
The cold-feel test, repeated in almost every guide, does not work. Obsidian and black glass have similar thermal behaviour, so a fake feels exactly as cold and warms at the same rate. A bead that warms unusually fast is plastic or thin-walled, which is worth knowing, but a cold bead tells you nothing.
Price is a filter, not a test. A very low price is a strong warning, and a high price is no guarantee; expensive dyed glass with a plated charm exists, and obsidian is cheap enough that a modest bracelet can be entirely genuine. A certificate is only as good as the laboratory that issued it and the number that can be checked; a generic card with no reference is packaging, not evidence.
Where to buy, and what evidence to ask for
Large marketplaces optimise for price, so glass and plated zinc dominate and natural claims go unenforced. Specialist jewellery shops and handmade marketplaces are better but uneven. The seller's willingness to be specific is the most useful signal: a listing that names the material, the treatment grade and the plating type, answers questions directly, and shows beads in daylight is more trustworthy than one that repeats the word natural.
Ask three things in writing before you pay. First, the exact material and treatment, for example natural Type A nephrite or black obsidian with no dye. Second, the metal: solid brass, 925 silver, gold-filled or gold-plated. Third, the return window in days, including whether a tested piece can still be returned. Check the piece on arrival before removing any tag, and test one bead rather than the whole strand. A seller who expects the piece to survive inspection will offer a return; that policy matters more than any claim in the description.
FAQ
Can real obsidian contain bubbles?
Not round trapped air bubbles. Mineral inclusions and cristobalite patches occur in nature, but the spherical bubbles left by casting do not. If you see them, the bead is glass or resin.
Is a heavier bead always real?
No. Weight separates stone from plastic and resin, but obsidian and black glass have nearly the same density. Combine weight with the torch test: heavy and opaque is reassuring, heavy and full of bubbles is still fake.
Is a gold-plated Pixiu bracelet fake?
Not if it is sold as gold-plated. It is a different product from solid gold, with a thin layer that wears at contact points. The problem is undisclosed plating or a plated piece priced as solid.
Can I tell treated jade at home?
Only by indicators. Dye in cracks, an unnaturally glassy surface and blue-white fluorescence under UV are warnings, not proof. For certainty, use a laboratory report.
A realistic standard
Two checks carry most of the weight: light reveals what a mould leaves inside, and a close look at the carving reveals whether a piece was cut or cast. Weight and hardness add useful negative evidence by catching plastic and resin, while the cold-feel test should be dropped altogether. Run the torch test first, compare beads second, and buy from someone who will take the piece back.
None of this requires expertise. It requires knowing which properties matter and refusing to rely on a single check.
