How to Tell if Cashmere is Real: 5 Tests You Can Do at Home
You’ve just purchased what you thought was a luxurious cashmere sweater, only to wonder: Is this actually real cashmere? You’re not alone. With nearly $1.4 billion of cashmere garments exported globally and cheaper versions flooding the market, distinguishing authentic cashmere from imposters has become increasingly challenging.
As a Nepal-based cashmere manufacturer that works directly with Himalayan goat herders and artisans, we at Diamond Knitland see this confusion daily. The cashmere market is filled with mislabeled products, synthetic blends marketed as “cashmere,” and even outright fakes. Whether you’re investing in your first cashmere piece or protecting yourself from counterfeit products, knowing how to verify authenticity is essential.
In this comprehensive guide, you’ll learn five reliable tests to determine if your cashmere is genuine—all from the comfort of your home. These are the same quality checks our artisans use in Nepal to ensure every Diamond Knitland piece meets authentic Himalayan cashmere standards. Let’s dive in.
Why Authentic Cashmere Matters
Before we explore the tests, let’s understand what makes real cashmere special and why counterfeits are so prevalent.
What is Real Cashmere?
According to the Cashmere and Camel Hair Institute, fabric is considered cashmere if it comes from the undercoat of a Capra hircus laniger (Cashmere goat), with fibers measuring no more than 19 microns in diameter. The finest cashmere, particularly Pashmina from the Himalayas, measures 15 microns or less.
Real cashmere comes from specific goat breeds found in high-altitude regions of Mongolia, China, Kashmir, and Nepal. These goats develop an incredibly soft undercoat to protect themselves from harsh winter conditions. Each goat produces only about 150 grams of usable fiber per year, which is why authentic cashmere commands premium prices.
At Diamond Knitland, we work directly with herders in Nepal’s Himalayan region who hand-comb Chyangra and Changthangi goats during the spring molting season. This traditional method—passed down through generations—ensures the finest fibers are collected without harming the animals, maintaining both quality and ethical standards.
The Counterfeit Problem
The proliferation of cheap cashmere has diluted the fabric’s luxe reputation, with lower-quality blends and occasional outright fraud becoming common. Some products labeled “cashmere” contain as little as 5% actual cashmere, with the rest being polyester, nylon, acrylic, or even cheaper animal fibers.
The stakes are high: You deserve to get what you pay for, and these tests will help ensure you do.
Test #1: The Touch Test (Fiber Fineness)
The touch test is your first line of defense and the most immediate way to assess cashmere authenticity.
How to Perform the Touch Test
Step 1: Feel the Fabric Hold the garment and gently rub it between your fingers. Authentic cashmere should feel smooth and soft without any roughness or itchiness.
Step 2: Check Against Your Skin Run the fabric over your chin or cheek, the most sensitive areas. Real cashmere should feel:
- Cloud-like and buttery smooth
- Warm to the touch, even at room temperature
- Soft without being slippery (over-processed cashmere feels slippery)
- Free of any scratchy or gritty sensation
Pro Tip from Diamond Knitland’s Quality Team: Our artisans in Nepal perform this exact test on every finished piece. If it doesn’t pass the “cheek test,” it doesn’t leave our workshop. The Himalayan cashmere fiber’s natural fineness (typically 14-16 microns in our pieces) creates that signature cloud-like softness.
Step 3: Compare Warmth Hold the fabric in your palm for 30 seconds. Real cashmere should feel warm and slightly heavy due to the density of the fibers, even when stored in a cool place.
What Fake Cashmere Feels Like
Red Flags:
- Scratchy or itchy texture – Indicates synthetic fibers or low-quality wool
- Overly slippery feel – Suggests over-processing or synthetic blending
- Gritty sensation – Means insufficient de-hairing; short, rough fibers remain
- No warmth transfer – Synthetic materials don’t conduct body heat like natural fibers
Why This Works: Real cashmere fibers are exceptionally fine (less than 18.5 microns in diameter) and bumpy, causing them to stick to themselves rather than sticking out, which creates that signature softness.
Test #2: The Burn Test (Most Definitive)
The burn test is the most scientifically reliable method to distinguish natural cashmere from synthetic fibers. However, it requires sacrificing a small piece of fabric.
How to Perform the Burn Test
What You’ll Need:
- A small thread or fringe from the garment (preferably from an inconspicuous seam)
- A lighter or match
- Tweezers or pliers (for safety)
- A fireproof surface (ceramic plate or metal dish)
Step-by-Step Instructions:
- Extract a Thread: Pull a single thread or small fringe from an inside seam or tag
- Hold with Tweezers: Grip the thread securely, keeping your fingers away from the flame
- Light It Up: Carefully bring the flame to the thread and observe what happens
- Note the Reaction: Watch how it burns, smells, and what remains
What Real Cashmere Does When Burned
If the thread shrinks from the flame, burns slowly, and smells like burnt hair, then it is cashmere. Here’s what to expect:
Burning Behavior:
- Shrinks or curls away from flame before igniting
- Burns slowly and may self-extinguish when flame is removed
- Smells like burnt hair or singed feathers (keratin protein)
- Leaves fine, powdery ash that crumbles easily and wipes away cleanly
- Creates small, dark, crushable residue
What Fake Cashmere Does When Burned
If it burns quickly, generates black smoke, continues to burn after the flame is removed, or smells like melting plastic, then it is most likely acrylic.
Synthetic Fiber Reactions:
Acrylic (most common fake):
- Burns rapidly with a bright flame
- Continues burning after removal from flame
- Produces black smoke
- Smells like burning plastic or chemicals
- Leaves hard, gritty beads or balls of residue
Polyester:
- Melts rather than burns
- Creates sticky, hard residue
- Sweet or chemical smell
- Black smoke production
Nylon:
- Melts and drips
- Hard bead formation
- Celery-like or chemical odor
Safety Warnings
⚠️ Important Safety Notes:
- Never burn fabric while wearing it
- Perform test in well-ventilated area
- Keep fire extinguisher or water nearby
- Use fireproof surface
- Dispose of burned material safely
- Avoid inhaling fumes from synthetic materials
Test #3: The Pilling Behavior Check
Pilling—those little balls of fiber that form on fabric—can actually tell you a lot about cashmere quality and authenticity.
Understanding Cashmere Pilling
First, let’s clear up a common misconception: Pilling can be a sign of quality cashmere, though it can also indicate lower-quality processing. Some pilling is normal and expected with genuine cashmere, especially during the first few wears.
What We Tell Our Diamond Knitland Customers: When you receive one of our Himalayan cashmere pieces, you might notice minimal pilling after the first 2-3 wears. This is actually a good sign—it means we haven’t over-processed the fiber with harsh chemicals. After washing once or twice, those loose short fibers wash away, and the pilling dramatically decreases. This is how authentic, minimally-processed cashmere behaves.
How to Perform the Pilling Test
Step 1: The Rub Test Rub the palm of your hand over the fabric surface. What happens?
Authentic Cashmere:
- May show slight pilling after extended wear and friction
- Should NOT pill instantly from hand rubbing
- Pills that do form should be minimal and easy to remove
- Quality improves after initial washing (excess short fibers wash out)
Low-Quality or Fake Cashmere:
- Lower quality cashmere will see fibers begin to roll up or pill immediately if you rub the palm of your hand over the fabric
- Excessive pilling right out of the box
- Pills are larger than normal
- Continuous pilling that worsens over time
Step 2: Check the Garment’s History If you already own the piece:
- Has it been worn 5-10 times?
- Have you washed it according to care instructions?
- Does it continue to pill excessively?
Why Pilling Happens
Pilling occurs with wear and friction, and while all natural fibers can pill to some extent, high-quality cashmere should not pill excessively.
Causes of Excessive Pilling:
- Shorter fiber lengths (cheaper material)
- Poor de-hairing process (mixed fiber lengths)
- Blending with synthetic materials
- Loose weave or knit construction
- Over-processing of fibers
The Bottom Line: Some pilling is natural, especially initially. But if a brand-new garment pills from a simple rub test, or if pilling is excessive and persistent, you’re likely dealing with inferior cashmere or a synthetic blend.
Test #4: The Weight-to-Warmth Ratio
One of cashmere’s most remarkable properties is its exceptional warmth relative to its light weight. This characteristic is nearly impossible for synthetics to replicate accurately.
How to Perform the Weight-to-Warmth Test
Step 1: The Lift Test Pick up your cashmere garment. Real cashmere feels light, but it keeps you warm. It should feel:
- Surprisingly lightweight for its size
- Substantial but not heavy
- Noticeably lighter than sheep’s wool
- Airy yet dense
Step 2: The Wearing Test Put on the garment for 10-15 minutes in a cool room.
Authentic Cashmere Will:
- Warm you quickly (within minutes)
- Regulate temperature (won’t overheat you indoors)
- Breathe naturally (prevents sweating)
- Maintain consistent warmth
- Feel like it’s insulating without suffocating
Synthetic or Low-Quality Will:
- Feel warm at first but not breathe well, causing overheating indoors
- Create clammy sensation from trapped moisture
- Feel heavier relative to warmth provided
- Take longer to warm your body
- Feel either too hot or not warm enough
The Science Behind It
Real cashmere’s superior warmth-to-weight ratio comes from:
- Hollow or semi-hollow fiber structure that traps air for insulation
- Fine diameter (14-19 microns) creates more fibers per inch
- Natural crimp in fibers creates tiny air pockets
- Moisture-wicking properties keep you dry and warm
Synthetic fibers typically cannot replicate this combination of lightweight construction and superior insulation.
Diamond Knitland Experience: Our customers in colder climates (from Canadian winters to Scandinavian regions) consistently report that our two-ply Himalayan cashmere sweaters keep them warmer than heavier wool coats while weighing half as much. This is the hallmark of authentic high-altitude cashmere—the goats themselves survive -40°F winters in these fibers.
Test #5: The Price Reality Check
While not a physical test, price is one of the most reliable indicators of cashmere authenticity. If the price seems too good to be true, it probably is.
Understanding Cashmere Pricing
Genuine cashmere garments typically range from $100 to $500 or more, depending on quality tier and brand positioning.
2024-2025 Price Guidelines
Budget Cashmere: $50-$150
- Likely contains shorter fibers
- May be thinner (single-ply)
- Could be cashmere blend (70-80% cashmere)
- Suitable for fashion pieces with shorter lifespan
- Brands: Uniqlo, H&M, Everlane (lower tier)
Mid-Range Cashmere: $150-$400
- Quality from brands like Cuyana, manufactured in Scotland and Italy
- Two-ply construction common
- Good fiber length and softness
- Expected lifespan: 5-10 years with care
- Direct-from-manufacturer pricing: Companies like Diamond Knitland offer this quality tier at $150-$250 because there’s no retail markup—you’re buying directly from the artisans who make it
- Brands: Naadam, Everlane, J.Crew, Jenni Kayne
Premium Cashmere: $400-$1,000+
- Longest, finest fibers (14-16 microns)
- Three-ply or specialty construction

Red Flag Prices
Be Suspicious Of:
- “100% cashmere” sweaters under $40
- Scarves under $30 marketed as cashmere
- Blankets under $100 claiming pure cashmere
- Drastically discounted luxury items from unknown sellers
Why Cheap “Cashmere” Exists:
- Some garments contain as little as 5% cashmere, with the rest polyester or nylon, yet are still marketed as “cashmere-blend”
- Synthetic materials (acrylic, rabbit fur) labeled as cashmere
- Counterfeit products from unauthorized manufacturers
- Low-grade, heavily processed cashmere
Calculate Cost Per Wear
Rather than just looking at upfront price, calculate value:
Formula: Purchase Price ÷ Number of Expected Wears = Cost Per Wear
Example:
- $200 quality cashmere sweater ÷ 100 wears = $2.00 per wear
- $40 fake cashmere sweater ÷ 10 wears = $4.00 per wear
Quality cashmere is an investment that pays off over time.
Common Fake Cashmere Materials (What to Avoid)
Understanding what materials are commonly passed off as cashmere helps you ask better questions and read labels more critically.
Synthetic Imposters
1. Acrylic (Most Common)
- Most faux fur and fake cashmere uses an 80/20 blend of acrylic and polyester fibers
- Made from petroleum-based chemicals
- Can feel initially soft but doesn’t breathe
- Fails burn test immediately (plastic smell, melts)
- Much cheaper to produce
2. Polyester
- Often blended with small amounts of real cashmere
- Doesn’t regulate temperature
- Pills excessively
- Melts when burned
- Creates static electricity
3. Viscose/Rayon
- Semi-synthetic fiber from wood pulp
- Can mimic softness temporarily
- Loses shape when washed
- Less durable than cashmere
- Often used in “cashmere blend” products
Animal Fiber Substitutes
4. Rabbit Fur/Angora
- Bunny faux fur is typically made from polyester or acrylic fibers processed to mimic rabbit fur’s soft texture
- Sometimes real rabbit fur is mislabeled as cashmere
- Softer than cashmere but less durable
- Much cheaper to produce
- Different fiber structure under microscope
5. Regular Sheep’s Wool
- Coarser fibers (25-40 microns vs. cashmere’s 14-19)
- Can be softened through chemical processing
- Itchier than genuine cashmere
- Heavier and less insulating
- Lower price point
6. Alpaca
- Legitimate luxury fiber (not a fake)
- Sometimes mislabeled as cashmere for markup
- Warmer but less soft than cashmere
- Different fiber properties
- Should be accurately labeled
How to Read Labels Carefully
Label Red Flags:
- “Cashmere-like” or “Cashmere feel”
- “Cashmere blend” without percentage specified
- No fiber content listed at all
- Products with percentages below 70% cashmere often contain mostly synthetic materials
What to Look For:
- “100% Cashmere” clearly stated
- Country of origin (Mongolia, China, Scotland, Nepal, Italy)
- Certification marks (GI tags, Good Cashmere Standard)
- Specific goat breed mentioned (Changthangi, Zalaa Jinst)
- Care instructions appropriate for natural fibers
Additional Verification Methods
Beyond the five main tests, here are supplementary checks for thorough authentication.
The Stretch Test
Authentic cashmere has natural elasticity allowing it to stretch slightly and return to its original shape with ease.
How to Test:
- Gently pull the fabric in both directions
- Hold for 5 seconds
- Release and observe
Real Cashmere: Springs back immediately, maintains shape Fake/Low-Quality: Remains stretched, loses shape, doesn’t recover
The Water Absorption Test
Real cashmere, being a natural fiber, has excellent absorbency and will absorb water almost instantly.
How to Test:
- Place a few drops of water on an inconspicuous area
- Observe absorption speed
- Check for color bleeding
Real Cashmere:
- Absorbs water quickly
- No color bleeding
- Dries naturally without water marks
Synthetic:
- Water beads up or repels
- Slow absorption
- May show water marks
The Weave Inspection
Genuine cashmere has a consistent, fine weave that contributes to its smooth texture.
How to Inspect:
- Hold fabric up to bright light
- Examine the weave pattern closely
Real Cashmere:
- Even, tight weave with no gaps
- Consistent density throughout
- No visible irregularities
- May show subtle diamond pattern in traditional pieces
Low-Quality:
- Loose weave
- Gaps between fibers
- Inconsistent density
- Thin spots
The Label Investigation
Check for:
- Manufacturing location (Scotland, Italy, Nepal, Mongolia)
- Specific fiber certifications
- Care instruction appropriateness
- Brand authentication features (holograms, serial numbers for luxury brands)

Caring for Your Authentic Cashmere
Once you’ve verified your cashmere is real, proper care ensures it lasts decades.
Washing Guidelines
Hand Washing (Recommended):
- Fill basin with cool water (60-70°F)
- Add wool-specific detergent
- Gently swish for 2-3 minutes (never rub)
- Rinse thoroughly until water runs clear
- Press (never wring) to remove water
- Lay flat on towel to dry
Machine Washing (If Necessary):
- Use delicate cycle
- Cold water only
- Wool-safe detergent
- Place in mesh bag
- Remove immediately when done
Frequency: Wash every 5-6 wears, or spot clean as needed
Storage Tips
- Fold, never hang (prevents stretching)
- Use breathable cotton bags
- Add cedar blocks or lavender sachets (moth repellent)
- Store in cool, dry place
- Clean before storing for season
Pilling Management
- Use cashmere comb (not razor)
- Gently remove pills after wearing
- Some pilling is normal initially
- Never use tape or scissors
Final Thoughts: Invest in Authenticity
Learning how to tell if cashmere is real protects both your wallet and your wardrobe. These five tests—touch, burn, pilling, weight-to-warmth, and price reality—give you the tools to verify authenticity before and after purchase.
Key Takeaways:
✅ Touch Test: Real cashmere feels soft, warm, and never scratchy
✅ Burn Test: Should smell like burnt hair, not plastic
✅ Pilling Test: Some pilling is normal; excessive is a red flag
✅ Weight-to-Warmth: Lightweight yet incredibly warm and breathable
✅ Price Check: Genuine cashmere starts around $100-150 for quality pieces
Remember, authentic cashmere is an investment that can last 10-20 years or more with proper care. A $200 quality sweater that lasts a decade costs far less per wear than a $40 fake that falls apart in one season.
When you buy authentic cashmere—especially from ethical sources like Nepal’s artisan communities—you’re investing in:
- Superior comfort and warmth
- Sustainable, natural fibers
- Fair wages for skilled artisans
- Timeless style that never goes out of fashion
- A garment that becomes softer with age
