Walk into any of the big high-street department stores and the "100% cashmere" shelf will be heaving. Most of what sits on it is not what the label claims. Industry surveys consistently estimate that around 30–40% of items labelled "100% cashmere" globally are either blended with rabbit hair, sheep wool, viscose, or are sold below the cost of genuine fibre — which is a strong signal of something off.
You do not need a laboratory to spot most fakes. Six tests, done in under a minute each, will keep you out of trouble.
1. The stretch test
Take a small section of the shawl or scarf between your thumb and forefinger of both hands. Gently stretch it.
Real cashmere stretches a little, then returns to its original shape immediately. The recovery is springy and complete.
Cashmere blended with wool stretches more and recovers slowly. You will see a slight deformation.
Cashmere blended with acrylic or polyester either stretches very little (acrylic is stiff) or stretches a lot and does not recover (cheap blends sag permanently).
2. The pull test
Gently rub the surface in a small circular motion with the pad of your finger. Then look closely.
Real cashmere will form a tiny amount of fluff — this is called the halo. A small halo is normal and even desirable; it shows the fibres are short, fine, and lightly twisted (all marks of quality). No halo at all usually means a tightly spun synthetic. Excessive halo or actual pilling under just one rub means short, low-grade fibres that will pill badly within weeks.
Grade AAA cashmere produces a barely perceptible halo. Grade A produces a more visible one — neither is bad, but they tell you what tier you are buying.
3. The temperature test
Lay the shawl flat against the back of your hand for ten to fifteen seconds.
Real cashmere warms to your skin almost immediately, because the fine, hollow-cored fibres trap air. Synthetic blends feel warm initially but quickly plateau; you can sense the slight plastic-y stillness of the air trapped against your skin.
If after twenty seconds the fabric feels distinctly warm and breathable, you are probably holding real cashmere or a high-percentage cashmere blend. If it feels merely insulating — almost stuffy — be suspicious.
4. The burn test (one fibre, at home)
If you have one loose fibre — a thread that has worked free from a hem — you can burn it. Do not burn the garment itself; this is purely for inspection of a single shed thread.
Real cashmere (animal protein) smells of burnt hair, leaves a soft black ash that crumbles to powder, and self-extinguishes the moment you remove the flame.
Synthetics (polyester, acrylic) smell of melting plastic, leave a hard black bead, and continue to flame or melt after the source is removed.
Cellulosic fibres (viscose, rayon, modal) smell of burnt paper and leave a soft grey ash. These are common adulterants in cheap "pashmina" shawls.
5. The price-per-gram check
Mid-grade cashmere fibre costs around $70–$110 per kilogram on the wholesale market. Top-grade (15–16 micron) fibre costs $130–$180 per kilogram. A typical men's cashmere scarf weighs around 150–180 grams.
This means the fibre cost of a real, mid-grade cashmere scarf is around £10–£14. Add weaving (≈ £8 in India, ≈ £40 in Italy), finishing, dyeing, labels, packaging, shipping, retailer margin, and marketing — and the rock-bottom honest retail price is somewhere around £80 for a basic scarf, £150 for a quality shawl, £400+ for a luxury blanket.
Anything under £25 labelled "100% cashmere" is essentially mathematically impossible as honest goods. The shawl is either blended, deeply discounted from old stock, or mislabelled outright. Use the £25/£80/£150 floor as a basic sanity check.
6. The label and provenance test
Real cashmere brands tell you:
- The fibre composition in percentages (not just "100% cashmere")
- The origin of the fibre (Inner Mongolia, Ladakh, Iran)
- The grade (A, AA, AAA — or the micron count, e.g. "14 micron")
- The place of manufacture (woven where; finished where)
- The care instructions (handwash cool, dry flat — anything else suggests blend)
Brands that hide all this behind "100% cashmere · made in Italy" are not necessarily fake, but they are choosing not to give you the information you would need to compare on equal terms.
What to do if you suspect you've been sold a fake
UK and EU consumer law treats fibre mislabelling as a serious misdescription. You are entitled to a full refund within the standard return window for any item whose labelled fibre content is materially incorrect. A textile fibre laboratory will issue a written test report for around £40–£60 — useful evidence if you intend to escalate.
For online purchases, retain the listing screenshot. Marketplaces (Amazon, eBay, Etsy) have specific category violations for textile mislabelling that lead to seller action.
A final word: it is fine to buy blends
None of this is an argument against blends. A 70% wool / 30% cashmere blanket is a wonderful object, often more durable than pure cashmere, and frequently better value. The problem is not blending — it is calling a blend "100% cashmere" and charging the customer for a fibre they are not receiving.
