The Cashmere Quality Guide
Authentication tests, grade comparisons, price benchmarks, and 12 myths debunked — everything you need to buy cashmere with confidence.
5 Authentication Tests You Can Do In-Store
No laboratory required. These five sensory and visual tests can separate genuine cashmere from imitations in under two minutes.
The Touch Test
Rub the fabric gently against your inner wrist or cheek — the most sensitive skin areas. Genuine Grade A cashmere (≤15.5 µm) causes zero irritation and feels like a warm breath of air. Any scratching or prickling indicates low-grade cashmere (Grade C), a heavy blend, or outright synthetic. Note: even genuine cashmere may feel slightly rough when brand new due to finishing; it softens after the first wash.
The Pilling Rub Test
Fold the fabric and rub two sections together briskly for 10–15 seconds. Genuine high-quality cashmere (long staple, well-constructed) will show minimal or no pilling in this test. Cheap cashmere (short staple, low ply) or synthetic blends will produce visible pills immediately. Some initial pilling in the first few wears is normal even for good cashmere — excessive instant pilling is a warning sign.
The Stretch & Recovery Test
Gently stretch a section of the fabric to about 150% of its length, hold for five seconds, then release. Genuine cashmere has natural elasticity from its crimped fibre structure and will spring back to near its original shape within a second or two. Poor-quality cashmere and synthetic blends lose their shape quickly and may show visible distortion in the stretched area. This test is particularly revealing for knitted garments.
The Light Test
Hold the garment up to a strong light source (daylight or a spotlight). Genuine tightly-woven or knitted cashmere should have an even, consistent density with no thin patches or uneven areas. You should see a warm, slightly translucent glow from the fibre itself. Synthetic fibres appear flat and plastic; cheap wool blends show uneven density. This test works best on knitted garments and woven accessories.
Read the Label (Carefully)
Under EU, US, and Indian textile labelling laws, any garment must accurately state fibre composition. Look for "100% Cashmere" — not "cashmere-blend," "cashmere-like," or just "wool." Country of origin should also be stated. Red flags: no composition label at all; "cashmere touch" or similar vague language; labels in only one language on an imported product. Legitimate high-end cashmere will often specify grade, micron count, and certifications.
The Price Sanity Check
This is not a tactile test, but it may be the most reliable indicator of all. Given that raw cashmere costs $80–$200 per kilogram, that a sweater uses 200–300g of fibre (plus dyeing, knitting, finishing, retail margin), genuine cashmere cannot be profitably sold at under £80–$100. If a "cashmere" sweater is priced below this threshold, the "cashmere" is either blended, mislabelled, or of very poor quality.
What Should Cashmere Cost?
Price is not the only indicator of quality — but it is the most immediate red flag for fraud.
Per sweater, depending on grade, ply, brand and origin
- • 100% composition label
- • Grade/micron often stated
- • Named country of fibre origin
- • GCS, OCS, or GI certification
- • Minimal initial pilling
May be genuine Grade C cashmere, a blend, or short-staple low-grade product
- • Likely Grade C (17–19 µm)
- • May be cashmere/wool blend
- • Apply tactile tests carefully
- • Expect more pilling over time
- • Shorter lifespan likely
Below the raw material cost threshold for genuine product
- • Acrylic or synthetic blend
- • Viscose/rayon "cashmere touch"
- • Mislabelled product
- • Will pill, stretch, lose shape quickly
- • Environmental and ethical concerns
